I have created a program to convert text to xml by using ReverseXSL API.
This program is to be executed by an application by calling static method (static int transformXSL).
I am able to execute and produce output with running from Eclipse. However, When I ran program (jar) by using application it stuck somewhere and I couldnt find anything.
Then, I debugged by "Debug as...-> Remote Java Application" in Eclipse from Application and found "InvocationTargetException" at ClassLoaders.callStaticFunction.
Below Static method is called by application.
public class MyTest4 {
public MyTest4()

I have a jLabel that is supposed to output the computer name based on an active directory search. The computer name gets assigned to the variable "CN" no problem, but it won't show up on the jLabel unless I run the gui again. How can I get the jLabel text to appear in real time within the same instance of the gui? The CN variable appears towards the bottom of the code posted.

I'm writing simple client - server application but I have stupid problem with this (it simplify example (everything is ok when i don't use java serialization)):
ServerSocket serversocket=null;
Socket socket=null;
String slowo=null;
try {
serversocket=new ServerSocket(8877);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
socket=serversocket.accept();
} catch (IOException e) {

e.printStackTrace();
}
try {
ObjectInputStream ois = new ObjectInputStream(socket.getInputStream());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
ObjectOutputStream oos=new ObjectOutputStream(socket.getOutputStream());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
slowo=(String)ois.readObject();
My compiler shows:
Serwer.java:51: cannot find symbol
symbol : variable ois

slowo=(String)ois.readObject();

1 error
Can anyone help?

It's out of scope by the time you get to line 51 because you declare it in the previous try.
Move the declaration outside of both, or write the code differently.
I consider this style to be cluttered and hard to read. I'd write it like this:
ServerSocket serversocket=null;
String slowo="";
try {
serversocket=new ServerSocket(8877);
Socket socket = serversocket.accept();
ObjectInputStream ois = new ObjectInputStream(socket.getInputStream());
ObjectOutputStream oos=new ObjectOutputStream(socket.getOutputStream());
slowo=(String)ois.readObject();
} catch (Exception e) {
e.printStackTrace();
} finally {
close(serversocket);
}
Don't let a bad IDE write bad code for you.
You should close your socket in a finally block.
I'm trying to save a url as a string so that I can use it in another part of my app but its not working properly. Here's what I have.
Saving
String FILENAME = "usertimetable";
String string = mWebView.getOriginalUrl();
FileOutputStream fos = null;
try {
fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
fos.write(string.getBytes());
fos.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Opening
FileInputStream fis = null;
try {
fis = openFileInput("usertimetable");
url = fis.toString();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Try using the read() method, rather than toString().

I asked a question earlier about extracting RAR archives in Java and someone pointed me to JUnrar. The official site is down but it seems to be quite widely used as I found a lot of discussions about it online.
Could someone show me how to use JUnrar to extract all the files in an archive? I found a little snippet online but it doesn't seem to work. It shows each item in the archive to be a directory even if it is a file.
Archive rar = new Archive(new File("C://Weather_Icons.rar"));
FileHeader fh = rar.nextFileHeader();
while(fh != null){
if (fh.isDirectory()) {
logger.severe("directory: " + fh.getFileNameString() );
}
//File out = new File(fh.getFileNameString());
//FileOutputStream os = new FileOutputStream(out);
//rar.extractFile(fh, os);
//os.close();
fh=rar.nextFileHeader();
}
Thanks.
May be you should also check this snippet code. A copy of which can be found below.

e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if (a != null) {
a.getMainHeader().print();
FileHeader fh = a.nextFileHeader();
while (fh != null) {
try {
File out = new File("/home/rogiel/fs/test/"
+ fh.getFileNameString().trim());
System.out.println(out.getAbsolutePath());
FileOutputStream os = new FileOutputStream(out);
a.extractFile(fh, os);
os.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (RarException e) {
// TODO Auto-generated catch block
