In an android app, having:
public class Pars extends Activity{
public Document docout(){
InputStream is = getResources().openRawResource(R.raw.talechap01);
Document docout = null;
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
try {
builder = domFactory.newDocumentBuilder();
docout = builder.parse(is);
} catch (ParserConfigurationException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (SAXException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return docout;
}
and
public class Manager {
public static String getStory(String spage, Document docs) {
XPathExpression expr;
XPath xpath = XPathFactory.newInstance().newXPath();
Object result = null;
String num = spage;
String par = null;
try {
expr = xpath.compile("//decision"+num+"/p//text()");
result = expr.evaluate(docs, XPathConstants.NODESET);
}
catch (XPathExpressionException e) {
e.printStackTrace();
}
NodeList nodes = (NodeList) result;
for (int i = 0; i < nodes.getLength(); i++) {
par = nodes.item(i).getNodeValue();
System.out.println(par);
}
return par;
}
}
Now I want to test the code.
public class Test {
public static void main(String[] args) {
try {Pars p = new Pars();
Document doc = p.docout();
System.out.println(Manager.getStory("000", doc));
}catch (Exception e){
e.printStackTrace();
}
}
}
I run "Test" as a java application and I get:

I tried to find how to fix it but cannot achieve it.
I have this answer from another question but I'm kind of noob yet and can't figure it out how to fix it.
You have defined your Pars class as extending the class Activity. The
error you are seeing is telling you that the class
android.app.Activity is not available on the classpath. Maybe you need
to check which libraries you import. – adamretter Mar 5 at 10:01
Thanks all.
The error is that you're trying to run a program that references Android classes (android.app.Activity) as a regular Java program that doesn't have Android runtime libraries in its classpath.
You should run Android apps as Android apps (on an emulator or a device) and regular Java programs as regular Java programs and not mix the two. Activity is Android; main() method is regular Java.
To learn Android app development, you can start with the developer.android.com getting started documentation.
The error message says it all. You are writing Android now. Trying to write a main method doesn't make any more sense in Android than it would if you were writing a webapp that runs in Tomcat. You are going to need to step back and read up on how Android works.

I want to parse a website with jsoup, and it succeeded to get the detail what I want, but I still get many many exceptions and not in catch
public static void main(String[] argv)

Element body = doc.body();
}catch (Exception e) {
System.out.println("------------google------------");
System.out.println("getGoogle:" + e.getMessage());

when I use debug mode found it was because doc = Jsoup.connect(url).get(); this line, but it looks ok after I search much info, below is exceptions I got

Also, this has been raised in SO as well, this (https://stackoverflow.com/a/47109099/6039974) answer might help you.
Im trying to write scripting system for a Minecraft Spigot plugin and im not quite sure on how to give my scripts the information from my main jar file.
With this current code it will compile the script fine but give me an error on line "3" of the Compass.java file (The class declaration). From what I see the program doesnt know what "com.deft.core.scripts.DeftScript" is and im not quite sure on how to tell it this information.
I got my compiling code from this thread if its relevant
Compiling the Script:
DiagnosticCollector<JavaFileObject> diagnostics = new DiagnosticCollector<JavaFileObject>();
JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
StandardJavaFileManager fileManager = compiler.getStandardFileManager(diagnostics, null, null);
List<String> optionList = new ArrayList<String>();
optionList.add("-classpath");
optionList.add(System.getProperty("java.class.path") + ";dist/Deft-Core.jar");
Iterable<? extends JavaFileObject> compilationUnit = fileManager.getJavaFileObjectsFromFiles(Arrays.asList(script));
JavaCompiler.CompilationTask task = compiler.getTask(null, fileManager, diagnostics, optionList, null, compilationUnit);
if (task.call()) {
Object obj = null;
try {
URLClassLoader classLoader = new URLClassLoader(new URL[]{new File("./plugins/Deft-Core/").toURI().toURL()});
Class<?> loadedClass;
loadedClass = classLoader.loadClass("scripts.Compass");
obj = loadedClass.newInstance();
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (MalformedURLException e) {
e.printStackTrace();
}
if (obj instanceof DeftScript) {
DeftScript deftScript = (DeftScript)obj;
deftScript.onEnable(this);
}
} else {
for (Diagnostic<? extends JavaFileObject> diagnostic : diagnostics.getDiagnostics()) {
System.out.format("Error on line %d in %s%n", diagnostic.getLineNumber(), diagnostic.getSource().toUri());
}
}
Compass.java
package scripts;
public class Compass extends com.deft.core.scripts.DeftScript {
#Override
public void onEnabled() {
}
}
DeftScript.java
package com.deft.core.scripts;
public abstract class DeftScript {
public abstract void onEnable();
}
With com.deft.core.scripts.DeftScript being the source im trying to extend from the main jarfile.
Im pretty sure my problem lies from somewhere within here:
List<String> optionList = new ArrayList<String>();
optionList.add("-classpath");
optionList.add(System.getProperty("java.class.path") + ";dist/Deft-Core.jar");
EDIT:
Fixed my problem with setting up the class path. My jar file in question was location in another location from what I specified.
I switch out the optionList.add calls with one
optionList.addAll(Arrays.asList("-classpath", System.getProperty("java.class.path") + ";./plugins/Deft-Core.jar"));
All tho this fixed my initial question now it as started causing a new error.
Apon trying to run my newly compiled class file it is giving me an error

I know there are similar questions out there but none of those solutions work for my case.
I tried to execute a Java file using Windows PowerShell.
This is what I have for Java file:
public class Demo1 {
public static void main (String arg[]){
System.out.println("DEMO1 START RUNNING");

} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
System.out.println("Unable to process");
}
System.out.println("DEMO1 JAVA COMPLETED.");
}
}
For easy compilation, I have copies of Demo1.java, Demo1.jar, and Demo1.class in the desktop directory.
for powershell command, I have tried:
1st attempt:
C:..\Desktop> java Demo1.java
2nd attempt:
C:..\Desktop> java -class Demo1.class
3rd attempt:
C:..\Desktop> java -jar Demo1.jar
All the above attempt return this error:

Since I am new to Java, I am really not getting what I am doing wrong here. This is my code (I do not think this is the issue, since the plugin fails to load ... :
String TWITTER_CONSUMER_KEY = "XXXXXXXX";
String TWITTER_SECRET_KEY = "XXXXXX";
String TWITTER_ACCESS_TOKEN = "XXXXXXXXXX";
String TWITTER_ACCESS_TOKEN_SECRET = "XXXXXX";
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true).setOAuthConsumerKey(TWITTER_CONSUMER_KEY).setOAuthConsumerSecret(TWITTER_SECRET_KEY).setOAuthAccessToken(TWITTER_ACCESS_TOKEN).setOAuthAccessTokenSecret(TWITTER_ACCESS_TOKEN_SECRET);
TwitterFactory tf = new TwitterFactory(cb.build());
Twitter twitter = tf.getInstance();
try {
Query query = new Query(Username);
QueryResult result;
do {
result = twitter.search(query);
List<Status> tweets = result.getTweets();
for (Status tweet : tweets)
{
String rawJSON = DataObjectFactory.getRawJSON(tweet);
try
{
BufferedWriter out = new BufferedWriter(new FileWriter((getDataFolder() + File.separator + "TwitterData.txt")));
out.write(rawJSON);
out.close();
}
catch (IOException ioe)
{
ioe.printStackTrace();
System.out.println("Failed to store tweets: " + ioe.getMessage());
}
}
}
while ((query = result.nextQuery()) != null);
System.exit(0);
}
catch (TwitterException te)
{
te.printStackTrace();
System.out.println("Failed to search tweets: " + te.getMessage());
System.exit(-1);
}
Why is Twitter4j not loading properly? Thanks!
EDIT: Also, the twitter4j-core-3.03.jar is in another directory on my computer. Is that a issue?
All jars needed by your Java program need to be on the classpath on the server. This includes Twitter4J in your case.
I'm trying to execute this code from the HTMLUnit tutorial:
final WebClient webClient = new WebClient();
final HtmlPage page = webClient.getPage("http://htmlunit.sourceforge.net");
but I get the MalformedURLException in the second line when saving it in Eclipse (if I compile and run the code, I get it too). What's the problem? TIA

I tried this in Eclipse 3.5 and it is working correctly, and the test is passing. I assume that you have included the necessary HTMLUnit JARs into your project? I took all the JARs from the HTMLUnit lib directory and added them to the build path of my project.
Also, can you catch the exception and post the stack trace here?
try {
final WebClient webClient = new WebClient();
final HtmlPage page = webClient.getPage("http://htmlunit.sourceforge.net");
assertEquals("HtmlUnit - Welcome to HtmlUnit", page.getTitleText());
}
catch (Exception e) {
e.printStackTrace();
}
package com.project.test;
import java.io.IOException;

public class Practice1 {
public static void main(String[] args) {
final WebClient webClient = new WebClient();
HtmlPage page;
try {
page = (HtmlPage) webClient.getPage("http://htmlunit.sourceforge.net");
System.out.println("Title="+ page.getTitleText());
} catch (FailingHttpStatusCodeException e) {

e.printStackTrace();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
Since in your stacktrace you have
Caused by: java.lang.ClassNotFoundException: org.apache.commons.httpclient.auth.CredentialsProvider
this isn't a malformed URL exception.
As confirmed by JARFinder, org.apache.commons.httpclient.auth.CredentialsProvider class should come from commons-httpclient-3.*.jar. Thus the cause of the problem must be that you don't have Commons HTTPClient 3.x JARs in your classpath.
