SWT app to .jar problems

Question

hi everybody,
I'm totally new in the java world and i've written my first java app last day:)
I was very proud but when i want to compile the program i ran in to some problems!
The system consists out of two separate layers.
In the main class i've made the interface (SWT) and there are some other classes that are doing the real work.
I've compiled the whole program with the SWT interface but it won't work!
But when i compile the classes that are doing the real work and write a small class that calls the other classes it works!
So the problem is the SWT but I can't solve it!
Some errors i've got :
java -classpath .;swt.jar -Djava.library.path=swt-win32-3346.dll -jar comp
ile.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/swt/widge
ts/Composite
and the succeeded built :
java -jar test.jar
