I am using this example to read from configuration file (data such as host name, password, etc) . But they did not include the Configurations class itself.
So I am not really sure how that should be implemented.
Here is how I am trying to read the properties from Main class:
Configurations configs = new Configurations(); // Error: cannot find symbol symbol: class Configurations location: class Main
try {
Configuration config = configs.properties(new File("database.properties"));
String dbHost = config.getString("database.host");
int dbPort = config.getInt("database.port");
String dbUser = config.getString("database.user");
String dbPassword = config.getString("database.password", "secret"); // provide a default
long dbTimeout = config.getLong("database.timeout");
} catch (ConfigurationException cex) {
cex.printStackTrace();
}
And this is how my database.properties file looks:
database.host = "dbname";
datatabase.port = 5005;
datatabase.user = "root";
datatabase.password = "";
database.timeout = 60000
P.S. Sorry for my stupidity, I am very new to Java.
You can use the properties class in java, which has a load method that specifies an inputstream.
Then, you can read your properties file via FileInputStream.
example：
public class Test {
public static void main(String[] args) throws Exception {
Properties properties = new Properties();
InputStream inputStream =
new FileInputStream("D:\\work_space\\java_workspace\\test-mq\\src\\main\\resources\\database.properties");
properties.load(inputStream);
String host = properties.getProperty("database.host");
// get more properties......
System.out.println(host);
}
}
Many in-house solutions come to mind. Like having the properties in a database and poll it every N secs. Then also check the timestamp modification for a .properties file and reload it.
But I was looking in Java EE standards and spring boot docs and I can't seem to find some best way of doing it.
I need my application to read a properties file(or env. variables or DB parameters), then be able to re-read them. What is the best practice being used in production?
A correct answer will at least solve one scenario (Spring Boot or Java EE) and provide a conceptual clue on how to make it work on the other
After further research, reloading properties must be carefully considered. In Spring, for example, we can reload the 'current' values of properties without much problem. But. Special care must be taken when resources were initialized at the context initialization time based on the values that were present in the application.properties file (e.g. Datasources, connection pools, queues, etc.).
NOTE:
The abstract classes used for Spring and Java EE are not the best example of clean code. But it is easy to use and it does address this basic initial requirements:
No usage of external libraries other than Java 8 Classes.
Only one file to solve the problem (~160 lines for the Java EE version).
Usage of standard Java Properties UTF-8 encoded file available in the File System.
Support encrypted properties.
For Spring Boot
This code helps with hot-reloading application.properties file without the usage of a Spring Cloud Config server (which may be overkill for some use cases)
This abstract class you may just copy & paste (SO goodies :D ) It's a code derived from this SO answer
// imports from java/spring/lombok
public abstract class ReloadableProperties {
#Autowired
protected StandardEnvironment environment;
private long lastModTime = 0L;
private Path configPath = null;
private PropertySource<?> appConfigPropertySource = null;
#PostConstruct
private void stopIfProblemsCreatingContext() {
System.out.println("reloading");
MutablePropertySources propertySources = environment.getPropertySources();
Optional<PropertySource<?>> appConfigPsOp =
StreamSupport.stream(propertySources.spliterator(), false)
.filter(ps -> ps.getName().matches("^.*applicationConfig.*file:.*$"))
.findFirst();
if (!appConfigPsOp.isPresent()) {
// this will stop context initialization
// (i.e. kill the spring boot program before it initializes)
throw new RuntimeException("Unable to find property Source as file");
}
appConfigPropertySource = appConfigPsOp.get();
String filename = appConfigPropertySource.getName();
filename = filename
.replace("applicationConfig: [file:", "")
.replaceAll("\\]$", "");
configPath = Paths.get(filename);
}
#Scheduled(fixedRate=2000)
private void reload() throws IOException {
System.out.println("reloading...");
long currentModTs = Files.getLastModifiedTime(configPath).toMillis();
if (currentModTs > lastModTime) {
lastModTime = currentModTs;
Properties properties = new Properties();
#Cleanup InputStream inputStream = Files.newInputStream(configPath);
properties.load(inputStream);
environment.getPropertySources()
.replace(
appConfigPropertySource.getName(),
new PropertiesPropertySource(
appConfigPropertySource.getName(),
properties
)
);
System.out.println("Reloaded.");
propertiesReloaded();
}
}
protected abstract void propertiesReloaded();
}
Then you make a bean class that allows retrieval of property values from applicatoin.properties that uses the abstract class
#Component
public class AppProperties extends ReloadableProperties {
public String dynamicProperty() {
return environment.getProperty("dynamic.prop");
}
public String anotherDynamicProperty() {
return environment.getProperty("another.dynamic.prop");
}
#Override
protected void propertiesReloaded() {
// do something after a change in property values was done
}
}
Make sure to add #EnableScheduling to your #SpringBootApplication
#SpringBootApplication
#EnableScheduling
public class MainApp {
public static void main(String[] args) {
SpringApplication.run(MainApp.class, args);
}
}
Now you can auto-wire the AppProperties Bean wherever you need it. Just make sure to always call the methods in it instead of saving it's value in a variable. And make sure to re-configure any resource or bean that was initialized with potentially different property values.
For now, I have only tested this with an external-and-default-found ./config/application.properties file.
For Java EE
I made a common Java SE abstract class to do the job.
You may copy & paste this:
// imports from java.* and javax.crypto.*
public abstract class ReloadableProperties {
private volatile Properties properties = null;
private volatile String propertiesPassword = null;
private volatile long lastModTimeOfFile = 0L;
private volatile long lastTimeChecked = 0L;

abstract protected void propertiesUpdated();
public class DynProp {
private final String propertyName;
public DynProp(String propertyName) {
this.propertyName = propertyName;
}
public String val() {
try {
return ReloadableProperties.this.getString(propertyName);
} catch (Exception e) {
e.printStackTrace();
throw new RuntimeException(e);
}
}
}
protected void init(Path path) {
this.propertyFileAddress = path;
initOrReloadIfNeeded();
}
private synchronized void initOrReloadIfNeeded() {
boolean firstTime = lastModTimeOfFile == 0L;
long currentTs = System.currentTimeMillis();
if ((lastTimeChecked + 3000) > currentTs)
return;
try {
File fa = propertyFileAddress.toFile();
long currModTime = fa.lastModified();
if (currModTime > lastModTimeOfFile) {
lastModTimeOfFile = currModTime;
InputStreamReader isr = new InputStreamReader(new FileInputStream(fa), StandardCharsets.UTF_8);
Properties prop = new Properties();
prop.load(isr);
properties = prop;
isr.close();
File passwordFiles = new File(fa.getAbsolutePath() + ".key");
if (passwordFiles.exists()) {
byte[] bytes = Files.readAllBytes(passwordFiles.toPath());
propertiesPassword = new String(bytes,StandardCharsets.US_ASCII);
propertiesPassword = propertiesPassword.trim();
propertiesPassword = propertiesPassword.replaceAll("(\\r|\\n)", "");
}
}
updateProperties();
if (!firstTime)
propertiesUpdated();
} catch (Exception e) {
e.printStackTrace();
}
}
private void updateProperties() {
List<DynProp> dynProps = Arrays.asList(this.getClass().getDeclaredFields())
.stream()
.filter(f -> f.getType().isAssignableFrom(DynProp.class))
.map(f-> fromField(f))
.collect(Collectors.toList());
for (DynProp dp :dynProps) {
if (!properties.containsKey(dp.propertyName)) {
System.out.println("propertyName: "+ dp.propertyName + " does not exist in property file");
}
}
for (Object key : properties.keySet()) {
if (!dynProps.stream().anyMatch(dp->dp.propertyName.equals(key.toString()))) {
System.out.println("property in file is not used in application: "+ key);
}
}
}
private DynProp fromField(Field f) {
try {
return (DynProp) f.get(this);
} catch (IllegalAccessException e) {
e.printStackTrace();
}
return null;
}
protected String getString(String param) throws Exception {
initOrReloadIfNeeded();
String value = properties.getProperty(param);
if (value.startsWith("ENC(")) {
String cipheredText = value
.replace("ENC(", "")
.replaceAll("\\)$", "");
value = decrypt(cipheredText, propertiesPassword);
}
return value;
}
public static String encrypt(String plainText, String key)
throws NoSuchPaddingException, NoSuchAlgorithmException, InvalidAlgorithmParameterException, InvalidKeyException, BadPaddingException, IllegalBlockSizeException, InvalidKeySpecException {
SecureRandom secureRandom = new SecureRandom();
byte[] keyBytes = key.getBytes(StandardCharsets.US_ASCII);
SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA256");
KeySpec spec = new PBEKeySpec(key.toCharArray(), new byte[]{0,1,2,3,4,5,6,7}, 65536, 128);
SecretKey tmp = factory.generateSecret(spec);
SecretKey secretKey = new SecretKeySpec(tmp.getEncoded(), "AES");
byte[] iv = new byte[12];
secureRandom.nextBytes(iv);
final Cipher cipher = Cipher.getInstance("AES/GCM/NoPadding");
GCMParameterSpec parameterSpec = new GCMParameterSpec(128, iv); //128 bit auth tag length
cipher.init(Cipher.ENCRYPT_MODE, secretKey, parameterSpec);
byte[] cipherText = cipher.doFinal(plainText.getBytes(StandardCharsets.UTF_8));
ByteBuffer byteBuffer = ByteBuffer.allocate(4 + iv.length + cipherText.length);
byteBuffer.putInt(iv.length);
byteBuffer.put(iv);
byteBuffer.put(cipherText);
byte[] cipherMessage = byteBuffer.array();
String cyphertext = Base64.getEncoder().encodeToString(cipherMessage);
return cyphertext;
}
public static String decrypt(String cypherText, String key)
throws NoSuchPaddingException, NoSuchAlgorithmException, InvalidAlgorithmParameterException, InvalidKeyException, BadPaddingException, IllegalBlockSizeException, InvalidKeySpecException {
byte[] cipherMessage = Base64.getDecoder().decode(cypherText);
ByteBuffer byteBuffer = ByteBuffer.wrap(cipherMessage);
int ivLength = byteBuffer.getInt();
if(ivLength < 12 || ivLength >= 16) { // check input parameter
throw new IllegalArgumentException("invalid iv length");
}
byte[] iv = new byte[ivLength];
byteBuffer.get(iv);
byte[] cipherText = new byte[byteBuffer.remaining()];
byteBuffer.get(cipherText);
byte[] keyBytes = key.getBytes(StandardCharsets.US_ASCII);
final Cipher cipher = Cipher.getInstance("AES/GCM/NoPadding");
SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA256");
KeySpec spec = new PBEKeySpec(key.toCharArray(), new byte[]{0,1,2,3,4,5,6,7}, 65536, 128);
SecretKey tmp = factory.generateSecret(spec);
SecretKey secretKey = new SecretKeySpec(tmp.getEncoded(), "AES");
cipher.init(Cipher.DECRYPT_MODE, secretKey, new GCMParameterSpec(128, iv));
byte[] plainText= cipher.doFinal(cipherText);
String plain = new String(plainText, StandardCharsets.UTF_8);
return plain;
}
}
Then you can use it this way:
public class AppProperties extends ReloadableProperties {
public static final AppProperties INSTANCE; static {
INSTANCE = new AppProperties();
INSTANCE.init(Paths.get("application.properties"));
}
#Override
protected void propertiesUpdated() {
// run code every time a property is updated
}
public final DynProp wsUrl = new DynProp("ws.url");
public final DynProp hiddenText = new DynProp("hidden.text");
}
In case you want to use encoded properties you may enclose it's value inside ENC() and a password for decryption will be searched for in the same path and name of the property file with an added .key extension. In this example it will look for the password in the application.properties.key file.
application.properties ->
ws.url=http://some webside
hidden.text=ENC(AAAADCzaasd9g61MI4l5sbCXrFNaQfQrgkxygNmFa3UuB9Y+YzRuBGYj+A==)
aplication.properties.key ->
password aca
For the encryption of property values for the Java EE solution I consulted Patrick Favre-Bulle excellent article on Symmetric Encryption with AES in Java and Android. Then checked the Cipher, block mode and padding in this SO question about AES/GCM/NoPadding. And finally I made the AES bits be derived from a password from #erickson excellent answer in SO about AES Password Based Encryption. Regarding encryption of value properties in Spring I think they are integrated with Java Simplified Encryption
Wether this qualify as a best practice or not may be out of scope. This answer shows how to have reloadable properties in Spring Boot and Java EE.
This functionality can be achieved by using a Spring Cloud Config Server and a refresh scope client.
Server
Server (Spring Boot app) serves the configuration stored, for example, in a Git repository:
#SpringBootApplication
#EnableConfigServer
public class ConfigServer {
public static void main(String[] args) {
SpringApplication.run(ConfigServer.class, args);
}
}
application.yml:
spring:
cloud:
config:
server:
git:
uri: git-repository-url-which-stores-configuration.git
configuration file configuration-client.properties (in a Git repository):
configuration.value=Old
Client
Client (Spring Boot app) reads configuration from the configuration server by using #RefreshScope annotation:
#Component
#RefreshScope
public class Foo {
#Value("${configuration.value}")
private String value;
....
}
bootstrap.yml:
spring:
application:
name: configuration-client
cloud:
config:
uri: configuration-server-url
When there is a configuration change in the Git repository:
configuration.value=New
reload the configuration variable by sending a POST request to the /refresh endpoint:
$ curl -X POST http://client-url/actuator/refresh
Now you have the new value New.
Additionally Foo class can serve the value to the rest of application via RESTful API if its changed to RestController and has a corresponding endpont.
I used #David Hofmann concept and made some changes because of not all was good.
First of all, in my case I no need auto-reload, I just call the REST controller for updating properties.
The second case #David Hofmann's approach not workable for me with outside files.
Now, this code can work with application.properties file from resources(inside the app) and from an outside place. The outside file I put near jar, and I use this --spring.config.location=app.properties argument when the application starts.
#Component
public class PropertyReloader {
private final Logger logger = LoggerFactory.getLogger(getClass());
#Autowired
private StandardEnvironment environment;
private long lastModTime = 0L;
private PropertySource<?> appConfigPropertySource = null;
private Path configPath;
private static final String PROPERTY_NAME = "app.properties";
#PostConstruct
private void createContext() {
MutablePropertySources propertySources = environment.getPropertySources();
// first of all we check if application started with external file
String property = "applicationConfig: [file:" + PROPERTY_NAME + "]";
PropertySource<?> appConfigPsOp = propertySources.get(property);
configPath = Paths.get(PROPERTY_NAME).toAbsolutePath();
if (appConfigPsOp == null) {
// if not we check properties file from resources folder
property = "class path resource [" + PROPERTY_NAME + "]";
configPath = Paths.get("src/main/resources/" + PROPERTY_NAME).toAbsolutePath();
}
appConfigPsOp = propertySources.get(property);
appConfigPropertySource = appConfigPsOp;
}
// this method I call into REST cintroller for reloading all properties after change
// app.properties file
public void reload() {
try {
long currentModTs = Files.getLastModifiedTime(configPath).toMillis();
if (currentModTs > lastModTime) {
lastModTime = currentModTs;
Properties properties = new Properties();
#Cleanup InputStream inputStream = Files.newInputStream(configPath);
properties.load(inputStream);
String property = appConfigPropertySource.getName();
PropertiesPropertySource updatedProperty = new PropertiesPropertySource(property, properties);
environment.getPropertySources().replace(property, updatedProperty);
logger.info("Configs {} were reloaded", property);
}
} catch (Exception e) {
logger.error("Can't reload config file " + e);
}
}
}
I hope that my approach will help somebody
As mentioned by #Boris, Spring Cloud Config is the way to go to avoid patchy solution. To keep the setup minimum, I will suggest the Embedding the Config Server Approach with native type (file type).
To support automatic config refresh without calling the actuator endpoint manually, I have created a directory listener to detect file changes and to dispatch refresh scope event.
Proof Of Concept repo (git)
For spring boot, there's a really good article on this topic here, but for multiple property files it doesn't work perfectly.
In my case I had 2 property files, one non sensitive and one containing the passwords. I proceeded with the following:
<dependency>
<groupId>commons-configuration</groupId>
<artifactId>commons-configuration</artifactId>
<version>1.10</version>
</dependency>
Extend the spring's PropertySource so that you can add the reloadable version to the environment.
public class ReloadablePropertySource extends PropertySource {
private final PropertiesConfiguration propertiesConfiguration;
public ReloadablePropertySource(String name, String path, ConfigurationListener listener) {
super(StringUtils.hasText(name) ? name : path);
try {
this.propertiesConfiguration = getConfiguration(path, listener);
} catch (Exception e) {
throw new MissingRequiredPropertiesException();
}
}
#Override
public Object getProperty(String s) {
return propertiesConfiguration.getProperty(s);
}
private PropertiesConfiguration getConfiguration(String path, ConfigurationListener listener) throws ConfigurationException {
PropertiesConfiguration configuration = new PropertiesConfiguration(path);
FileChangedReloadingStrategy reloadingStrategy = new FileChangedReloadingStrategy();
reloadingStrategy.setRefreshDelay(5000);
configuration.setReloadingStrategy(reloadingStrategy);
configuration.addConfigurationListener(listener);
return configuration;
}
}
Now add all of your properties files (now reloadable) inside the spring's env
#Configuration
public class ReloadablePropertySourceConfig {
private final ConfigurableEnvironment env;
#Value("${spring.config.location}")
private String appConfigPath;
#Value("${spring.config.additional-location}")
private String vaultConfigPath;
public ReloadablePropertySourceConfig(ConfigurableEnvironment env) {
this.env = env;
}
#Bean
#ConditionalOnProperty(name = "spring.config.location")
public ReloadablePropertySource getAppConfigReloadablePropertySource(){
ReloadablePropertySource rps = new ReloadablePropertySource("dynamicNonSensitive", appConfigPath, new PropertiesChangeListener());
MutablePropertySources sources = env.getPropertySources();
sources.addFirst(rps);
return rps;
}
#Bean
#ConditionalOnProperty(name = "spring.config.additional-location")
public ReloadablePropertySource getVaultReloadablePropertySource(){
ReloadablePropertySource rps = new ReloadablePropertySource("dynamicVault", vaultConfigPath, new PropertiesChangeListener());
MutablePropertySources sources = env.getPropertySources();
sources.addFirst(rps);
return rps;
}
private static class PropertiesChangeListener implements ConfigurationListener{
#Override
public void configurationChanged(ConfigurationEvent event) {
if (!event.isBeforeUpdate()){
System.out.println("config refreshed!");
}
}
}
}
From the article
We've added the new property source as the first item because we want it to override any existing property with the same key
In our case, we have 2 "reloadable" property sources and both will be looked up first.
Finally create one more class from which we can access the env's properties
#Component
public class ConfigProperties {
private final Environment environment;
public ConfigProperties(Environment environment) {
this.environment = environment;
}
public String getProperty(String name){
return environment.getProperty(name);
}
}
Now you can autowire ConfigProperties and always get the latest property in the files without requiring to restart the application.
#RestController
#Slf4j
public class TestController {
#Autowired
private ConfigProperties env;
#GetMapping("/refresh")
public String test2() {
log.info("hit");
String updatedProperty = env.getProperty("test.property");
String password = env.getProperty("db.password");
return updatedProperty + "\n" + password;
}
}
where test.property is coming from 1st file and db.password is coming from another.
If you want to change the properties at realtime and don't want to restart the server then follow the below steps:
1). Application.properties
app.name= xyz
management.endpoints.web.exposure.include=*
2). Add below dependencies in pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-rest</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-context</artifactId>
<version>2.1.1.RELEASE</version>
</dependency>
3).Place application.properties in /target/config folder. Create the jar in /target folder
4).add a classas below ApplcationProperties.java
#Component
#RefreshScope
#ConfigurationProperties(prefix = "app")
public class ApplicationProperties {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
5). Write Controller.java and inject ApplcationProperties
#RestController
public class TestController {
#Autowired
private ApplicationProperties applcationProperties;
#GetMapping("/test")
public String getString() {
return applcationProperties.getName();
}
}
6).Run the spring boot application
Call localhost:XXXX/test from your browser
Output : xyz
7). Change the value in application.properties from xyz to abc
8). Using postman send a POST request to localhost:XXXX/actuator/refresh
response: ["app.name"]
9). Call localhost:XXXX/find from your browser
Output : abc
Im trying to open a page using java and selenium on port 8080. Ive tried using the page and :8080 but the page continually keeps opening on a different port. Im basically trying to use zap and it configured to use firefox on port 8080. ANy help appreciated. Ive added my test and my class thats added to the test below, i think somewhere int he driver part it must call a different port but i cant see how this is happening
Test:
public class ZapScanTest {
static Logger log = Logger.getLogger(ZapScanTest.class.getName());
private final static String ZAP_PROXYHOST = "127.0.0.1";
private final static int ZAP_PROXYPORT = 8080;
private final static String ZAP_APIKEY = null;
// Change this to the appropriate driver for the OS, alternatives in the
drivers directory
private final static String FIREFOX_DRIVER_PATH =
"drivers/geckodriver.exe";
private final static String MEDIUM = "MEDIUM";
private final static String HIGH = "HIGH";
private ScanningProxy zapScanner;
private Spider zapSpider;
private WebDriver driver;
private Dec myApp;
private final static String[] policyNames = {"directory-browsing","cross-
site-scripting","sql-injection","path-traversal","remote-file-
inclusion","server-side-include",
"script-active-scan-rules","server-side-code-injection","external-
redirect","crlf-injection"};
int currentScanID;
#Before
public void setup() {
zapScanner = new
ZAProxyScanner(ZAP_PROXYHOST,ZAP_PROXYPORT,ZAP_APIKEY);
zapScanner.clear(); //Start a new session
zapSpider = (Spider)zapScanner;
log.info("Created client to ZAP API");
driver = DriverFactory. createProxyDriver("firefox",createZapProxyConfigurationForWebDriver(), FIREFOX_DRIVER_PATH);
myApp = new Dec(driver);
//myApp.registerUser(); //Doesn't matter if user already exists, bodgeit just throws an error
}
#After
public void after() {
driver.quit();
}
#Test
public void testSecurityVulnerabilitiesBeforeLogin()throws Exception {
myApp.login();
log.info("Spidering...");
spiderWithZap();
log.info("Spider done.");
setAlertAndAttackStrength();
zapScanner.setEnablePassiveScan(true);
scanWithZap();
List<Alert> alerts = filterAlerts(zapScanner.getAlerts());
logAlerts(alerts);
assertThat(alerts.size(), equalTo(0));
}
Dec class:
public class Sportdec {
WebDriver driver;
final static String BASE_URL = "https://web-game-stage.dec.com/games:8080";
final static String USERNAME = "dec2009#hotmail.com";
final static String PASSWORD = "tables";
public Dec(WebDriver driver) {
this.driver = driver;
this.driver.manage().timeouts().pageLoadTimeout(5, TimeUnit.SECONDS);
this.driver.manage().timeouts().implicitlyWait(5,TimeUnit.SECONDS);
}
public void login()throws Exception {
driver.get(BASE_URL);
Header header = new Header();
header.guest_select_login();
Pages.Login login = new Pages.Login();
login.login_with_empty_fields();
login.login_with_invalid_email();
login.email_or_password_incorrect();
login.login_open_and_close();
}
By any chance have you tried using this
final static String BASE_URL = "https://web-game-stage.dec.com:8080/games";
instead of this
final static String BASE_URL = "https://web-game-stage.dec.com/games:8080";
You are adding port number to the games directory instead of the host
I wrote below program to download SharePoint lists. But I am getting errors while using sharepointclient and listsoapstub. Does they have any dependency on other API's or jar files ? If so, what will be those ?

this.password = password.toCharArray();
}
#Override

}
I'm guessing that you got the code that you "wrote" from here:
http://blog.ashwani.co.in/blog/2013-07-28/connect-and-access-sharepoint-webservice-from-java/
(Your code looks strikingly similar to that code!)
I think the answer to your question is covered in these described in that blog posting:
Step 1. Download the wsdl files from the sharepoint.
Step 2. Generate Java Stubs for these wsdls
Step 3. Place the WSDLs in your resources
Once you have done that, you should be able to add imports for the relevant classes to the classes that you wrote.
From what I have read the correct connection string for a jTDS is:
jdbc:jtds:<server_type>://<server>[:<port>][/<database>]
I believe the issue is the server name. The server name is formatted like this
servername\adhoc
An SQLException gets thrown anytime I try to connect saying "unknown server host name"
Is that my issue, or is there something else I need to look into as well...?
import java.sql.*;
public class Main {
// The JDBC Connector Class.
private static final String MSdbClassName = "net.sourceforge.jtds.jdbc.Driver";
private static final String MSHOST = "servername\\adhoc"; //cascrmeufosqlp1\adhoc
private static final String MSDATABASE = "tier2";
private static final String MSUSER = "feed_****2";
private static final String MSPASSWORD = "*******0";
public static void main(String[] args) throws ClassNotFoundException,SQLException
{
Class.forName(MSdbClassName);
String url2 = "jdbc:jtds:sqlserver://" + MSHOST + ":1433/" + MSDATABASE;
Connection c2 = java.sql.DriverManager.getConnection( url2, MSUSER, MSPASSWORD );
System.out.println("MS SQL works...");
c2.close();
}
}
It looks like you are trying to connect to a "named instance" of sql server. You will need to use the "instance" property in the url. Something like this might work:
jdbc:jtds:sqlserver://servername:1433/dbName;appName=MyAPP;instance=instanceName
See the jTDS faq for more information found here: http://jtds.sourceforge.net/faq.html
