Greetings, ravit!

Looks like are having IDE problems... are you using an IDE other than Eclipe to run your app...

You can download a free version of Eclipse to try the code.

You can also post the whole code for easy access, in case someone see something else that could be problematic.

In a bit!

Great! An unknown error and no code to work with! I'm absolutely sure, your error is in line #104, the 4th character...

OK, seriously now. We can't help you, if we don't know your code. Generally, I'd try commenting out some sections of the code and check if the error still occurs - that way you can limit the area the error may be. But if you want any further help, we'll need to see some code.

Greetings,
Nepomuk

@Dököll
It is not an IDE problem; it has to do with SWT and by coincidence Eclipse also is bundled with those libraries (which it uses itself) and is made available to the user as well, Stop pointing to those IDEs all the time; they're innocent.

kind regards,

Jos
