Maybe you should write 'Phone Number' in one word like PhoneNumber.
Or write Phone Number with backticks around the words in the insert statement - in the create statement you used backticks around the field names.
You have an error in your SQL syntax; check the manual that corresponds to
your MySQL server version for the right syntax to use near 'Number)
values('sdsdsd','Male',23,'sdsdsd','232323')'
'Number is probably the second part of 'Phone Number'.

You have Phone Number in your SQL query.
In your code, you open and close the connection every time the method is used
You can move the connection and the close-in separate methods
For example :
public Connection connect() throws SQLException {
Connection connection = null;
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
connection = DriverManager.getConnection(URL,USER,PASSWORD);
return connection;
}
public void disconnect(Connection connection) throws SQLException {
connection.close();
}

Maybe you can try instead of:
String url = "jdbc:mysql://localhost:3306/studentmanagement?&useSSL=false"
Try:
String url = "jdbc:mysql://localhost:3306/studentmanagement?autoReconnet=true&useSSL=false"

Connecting JAVA with MySql using JDBC

This is the code that i have tried. But everytime it shows the Error:Could not create connection to database server.What is the error in the code?Is the url syntax correct?
import java.sql.*;
public class Second {
public static void main(String[] args) {
Connection con = null;
try {
String url = "jdbc:mysql://localhost:3306/sakila";
String user = "root";
String password = "1234";
Class.forName("com.mysql.jdbc.Driver");
con = DriverManager.getConnection(url, user, password);
System.out.println("Connection is established.");
con.close();
}
catch(Exception e) {
e.printStackTrace();
}
}
}
I've posted the StackTrace here.What is the Null pointer Exception I am getting?

MAC OS com.mysql.cj.exceptions.CJCommunicationsException: Communications link failure

I am trying to figure out why my app has trouble connecting to my database, only on mac OS so I'm using a small program to run on terminal on OS to see what was causing that.
It seems the hostname is causing the issue, but my service provider cannot give me an ip address to try if it fixes my issue. Does anyone have a fix for this or an idea on what I could try? Thanks a lot for your time.
here is the connection program. the database user can select only, the hostname is correct and password as well. This issue only happens on MAC OS and not all the time. My database accepts conneciton from all ip, I used a wildcard. Any idea on what to try next is appreciated.
import java.sql.Connection;
import java.sql.DriverManager;

public static void main(String[] args) {
System.out.println("\nMySQL JDBC Connection To G4THER DBase Tester");
Connection conn = null;

String userName = "app";
String password = "password";
String url = "jdbc:mysql://hostname:3306/dbase";
conn = DriverManager.getConnection(url, userName, password);
System.out.println("\nDatabase Connection Established...");
Thread.sleep(1500L);
}
catch (Exception ex) {
System.err.println("Cannot connect to database server");
ex.printStackTrace();

Thread.sleep(1500L);
conn.close();

thanks

I was able to fix the issue using an IP address instead of the hostname. I used a site to find the IP with the hostname and changed my code. So far so good.

How can I enable RSA15 transport algorithm in WSS4J 2.2.3?

I'm upgrading a SOAP web service client to JDK 11 and WSS4J 2.2.3 (w/o CXF/Spring). The java code uses the 'stand-alone' approach to handle encryption and fails to decrypt the incoming response because it is encrypted using RSA15. The algorithm was disabled by default as of release 2.0.0 but the migration guide suggests that it is possible to enable the algorithm by setting the WSHandlerConstants.ALLOW_RSA15_KEY_TRANSPORT_ALGORITHM property to "true". How can I do this??
I've looked at the WSS4J code and can see that the RequestData object is instantiated from WSSecurityEngine class in the WSS4J framework and I don't see a hook that would allow me to set the allowRSA15KeyTransportAlgorithm property to 'true'. I've been able to put a break-point in eclipse and change the value to ensure it works as expected and it does. I've searched the web and the closest thing I found was a similar question with no apparent answer here Allow the RSA v1.5 Key Transport Algorithm for WildFly / JBossWS / CXF / WSS4J stack. I've tried to revert WSS4J back to version 1.6 which allows the algorithm but then it failed with a different error "WRONG_DOCUMENT_ERR: A node is used in a different document than the one that created it". This seems to occur when using WSS4J 1.6 with any version of jaxws (external to JDK). The only way I can think to solve this is by hacking into the WSS4J 2.2.3 dependency and setting the property default to "true" in the RequestData class but I really don't want to do that.

After a good bit of tracing.. I managed to find it for ya.
Long story short, you should instead create a RequestData object for yourself, like this:
private void inboundWSSConfig(SOAPMessageContext context, Crypto crypto) throws WSSecurityException{
log.info("Inbound Message...");
KeystoreCallbackHandler keystoreCallbackHandler = new KeystoreCallbackHandler();
keystoreCallbackHandler.addUsers((String)cryptoProperties.get("org.apache.ws.security.crypto.merlin.keystore.alias"),
(String)cryptoProperties.get("org.apache.ws.security.crypto.merlin.keystore.password"));
WSSecurityEngine newEngine = new WSSecurityEngine();
WSSConfig config = WSSConfig.getNewInstance();
config.setValidator(WSConstants.SIGNATURE, new SignatureTrustValidator());
newEngine.setWssConfig(config);
RequestData data = new RequestData();
data.setWssConfig(config); // probably
data.setDecCrypto(crypto);
data.setSigVerCrypto(crypto);
data.setCallbackHandler(keystoreCallbackHandler);
data.setAllowRSA15KeyTransportAlgorithm(true);
newEngine.processSecurityHeader(context.getMessage().getSOAPPart(), data);
}
Here's how I discovered this solution by working backward through the stack trace and looking at the source:
Starting where the exception is thrown
at org.apache.wss4j.dom.processor.EncryptedKeyProcessor.handleToken(EncryptedKeyProcessor.java:131)
public List<WSSecurityEngineResult> handleToken(Element elem, RequestData data, AlgorithmSuite algorithmSuite) {
// ...
if (WSConstants.KEYTRANSPORT_RSA15.equals(encryptedKeyTransportMethod)
&& !data.isAllowRSA15KeyTransportAlgorithm() // <=== because this is false, etc.
&& (algorithmSuite == null
|| !algorithmSuite.getKeyWrapAlgorithms().contains(WSConstants.KEYTRANSPORT_RSA15))) {
LOG.debug(
"The Key transport method does not match the requirement"
);
throw new WSSecurityException(WSSecurityException.ErrorCode.INVALID_SECURITY); // <=== this is where you die
}
// ...
}
It dies because the requestData does not have allowRSA15KeyTransportAlgorithm set to true.
But why is it not set to true? where is request data coming from?
at org.apache.wss4j.dom.processor.EncryptedKeyProcessor.handleToken(EncryptedKeyProcessor.java:90)
at org.apache.wss4j.dom.engine.WSSecurityEngine.processSecurityHeader(WSSecurityEngine.java:340)
at org.apache.wss4j.dom.engine.WSSecurityEngine.processSecurityHeader(WSSecurityEngine.java:221)
All just pass along the requestData created in this method:
// line 208
public WSHandlerResult processSecurityHeader(
Element securityHeader,
String actor,
CallbackHandler cb,
Crypto sigVerCrypto,
Crypto decCrypto
) throws WSSecurityException {
RequestData data = new RequestData(); // creates RequestData but doesn't set `allowRSA15KeyTransportAlgorithm`
data.setActor(actor);
data.setWssConfig(getWssConfig());
data.setDecCrypto(decCrypto);
data.setSigVerCrypto(sigVerCrypto);
data.setCallbackHandler(cb);
return processSecurityHeader(securityHeader, data); // line 221
}
which is called by:
public WSHandlerResult processSecurityHeader(
Document doc,
String actor,
CallbackHandler cb,
Crypto crypto
) throws WSSecurityException {
return processSecurityHeader(doc, actor, cb, crypto, crypto);
}
which you call in your inboundWSSConfig method.
So because you are calling processSecurityHeader(Document doc, String actor, CallbackHandler cb, Crypto crypto) it's initializing a new RequestData and setting the Crypto and CallbackHandler on it but never setting allowRSA15KeyTransportAlgorithm.

Creating JDBC Connection Pool in Java [duplicate]

This question already has answers here:
Java JDBC Access denied for user [closed]
(4 answers)
Closed 5 years ago.
I am newbie with java and i need help with how to create connection pool for JDBC in my java application project.
I have been able to connect to my database but the performance of my application is slow since i call on the connection on every frame as i saw on a lots of video tutorials on youtube.
This is how i connect to the database. I call on the connection in every frame like DBConnection.getConnectDB() in most of my frame.
How can i create a JDBC connection pool for java in netbeans. Thank you
DBConnect
public class DBConnection {
public static Connection ConnectDB(){
try{
Class.forName("com.mysql.jdbc.Driver");
Connection conn = DriverManager.getConnection("jdbc:mysql://server/db_name","user","pass");
System.out.println("Connected");
return conn;
}
catch(Exception ex){
JOptionPane.showMessageDialog(null, ex);
return null;
}}
}
update
public static Connection ConnectDB(){
HikariConfig config = new HikariConfig();
config.setJdbcUrl("jdbc:mysql://localhost:3306/simpsons");
config.setUsername("username");
config.setPassword("pass");
config.addDataSourceProperty("cachePrepStmts", "true");
config.addDataSourceProperty("prepStmtCacheSize", "250");
config.addDataSourceProperty("prepStmtCacheSqlLimit", "2048");
HikariDataSource ds = new HikariDataSource(config);
return (Connection) new HikariDataSource(config);
}
}

If you are using maven or gradle (you should be) you can use a pool like HikariCP and create a jdbc connection pool like this.
HikariConfig config = new HikariConfig();
config.setJdbcUrl("jdbc:mysql://localhost:3306/simpsons");
config.setUsername("bart");
config.setPassword("51mp50n");
config.addDataSourceProperty("cachePrepStmts", "true");
config.addDataSourceProperty("prepStmtCacheSize", "250");
config.addDataSourceProperty("prepStmtCacheSqlLimit", "2048");
HikariDataSource ds = new HikariDataSource(config);
Here is a more detailed example configuring multiple hikaricp pools
