Problem with Class Path in Eclipse

I'm using the esclipe IDE and I added a jarfile to my program by going to properites-->build path> libraries and added it there. But when I compile it, I get this error saying

Exception in thread"main" java.lang.NoClassDefFoundError: org/apache/avalon/framework/configuration/ConfigurationException

Can anyone help me with this problem?

Does the library appear in the package explorer? p.s. this is possibly a pure eclipse problem and people might tell you to go to their forums

Yea it appears in the explorer and I am able to import classes from the jar file.

Is the jar you imported the only one you need? See if it has a dependency on any others, you'll need them, too. This doesn't look like an Eclipse problem, just a classpath omission

Yea, is the only jar that come in the binary files I downloaded. Its an Apache FOP, like HSSF(if ur familiar with that).

That's not what I asked! A lot of libraries will require that you download other libraries as well (Apache projects are particularly notorious for this), check the download page for it. What jar was it? Either you've forgotten a library, or you've misconfigured something, but I'd check for missing libraries first

Yea, it is the only required library. None of the other were mentioned on the site and the class that I'm looking for is inside the jar file.

Wait, I take th back, there is another jar called avalon so I downloaded it and added to the class paths in esclipe but is saying its still not there.

Does the new jar file you downloaded actually include the class that's named in that error message?

Thnx, i got it working. It wasn't the jar, it was that I needed 10 other jars to go along with it.Pain the *ss.
