Compiling Error

Hi,
I am trying to compile a SimpleApplet file on mac osx. But I am getting the following error.

Can't open input server /Library/InputManagers/QuicKeysIM
Exception in thread "main" java.lang.NoSuchMethodError: main
Please tell me what is this QuicKeysIM and where I am doing wrong?

Are you sure that's a compile-time error? Or are you seeing that error when you try to run something?

That error is telling you that the file you're trying to run (seemingly QuickKeysIM) does not include a main(String[] args) method and is therefore not runnable.
