Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/swt/widgets/Display [message #465546] Thu, 15 December 2005 01:56 Go to next message

Hello,

I have a problem with starting my SWT application from a jar file
under Windows XP. In Eclipse everything works fine. But when I
run the jar file I get this error:

Exception in thread "main" java.lang.NoClassDefFoundError:
org/eclipse/swt/widgets/Display

I have copied swt.jar and swt-win32-3064.dll to the jars
directory. And I have added the swt.jar to the manifest file.

I tried this when I started with my project and it worked. Now I
get the above error.

Thanks,

Nick

Did you point to the directory where you moved the dll in your
java.library.path command line option?

Yes, I started with

java -Djava.lirary.path="D:\path_to_dll_and_jars" -jar myjar.jar

but I get the same error as before.

I think it should even work without the java.library.path option
because the dll and all the jars are in the same directory.

Any more ideas?

Hope this is just a cut & paste error but you spelled -Djava.lirary not
-Djava.library

Yes, it is just a cut&paste error. It was on two lines. Sorry.

Have you tried starting your application using jar in the classpath and
specifiing the startup class manually? Do you get the same result?

Regards
Stefan

Thank you, I have found the error. The manifest file was wrong.
I separated the jars with a ',' and not with a space.

With "Class-Path: swt.jar, jdom.jar" only jdom.jar was used. With
"Class-Path: swt.jar jdom.jar" everything works fine.

Thanks again,
Nick
