Hi Jana,

the thing is:

The gwt-compiler needs the java-code of all classes you want to need
in your
client-side (gwt) code. The compiler needs the code, because it parses
java to javascript.
So if you want to use external jars, than you must be sure, that the
source-code is available.
If you are using Eclipse, you can attach source to the jars in the
build path.
If you don´t have the source-code of the jar, you can´t use this
library in the client.

If you need the library for services, just use the jar only on the
server-side, there, you don´t
need to know the source-code of used jars. Be sure that you have a
copy of the jar in the war/WEB-INF/lib/ folder,
or it throws: classBotFound-Exception.
