java.lang.NoClassDefFoundError error!

Hi all,

I'm trying to run my own .jar file, it refers classes collected in another jar file. Both of this ".jar" files are in same directory. When all of this classes were under developing everything was ok, but now, when I separated this classes in different jars, there is something wrong! I really don't know what is it!!!!!!!!!!!!!
I'm trying with this line : "java -jar my.jar someparameters"
My classpath also seems ok, I added "." at the begining of my classpath as well, but I'm still getting this error : Exception in thread "main" java.lang.NoClassDefFoundError: sss/com/DocListener.
Any suggestions?
Thanks in advance!

Add a Class-Path attribute to your manifest to reference the other jar

eg.

Class-Path: A.jar

Then run it with:

java -jar B.jar

It also does not works! I tried it as well, but I forgot to mention this in my question. When all of this classes are in same jar they work fine, but now they don't work. It seems like problem of class loader or something else?!?!
I don't know!

Does you jar have the file DocListener?

What happens if you do (assumin *nix):

jar -tfv <your jar> | grep DocListener

ValeriAuthor Commented:
The DocListener class is in jar A. Yes, the jar A contains DocListener class, I checked this...

Can you tell me where *exactly* the A.jar file is, the B.jar file is, what is your current working directory and the command you are using to run them?

Giant2Commented:
If you open the A.jar do you find DocListener.class in sss/com/ directory?

ValeriAuthor Commented:
Yes, my class exists in A.jar.
I'm using this command :  "java -classpath A.jar -jar B.jar someparameters" . The class with main method is in B.jar and java is looking for the class in A.jar. The error that I'm getting is : Exception in thread "main" java.lang.NoClassDefFoundError: sss/com/DocListener. Both of the jar files are in the project directory!

Ok, but if you open the A.jar do you find DocListener.class in the directory

sss/com/

?
