Have you tried to put in the server's lib directory?
$JBOSS_HOME/server/default/lib if you're using the default server.
You can also declare your lib with a java module inside application.xml
Yes, jaxen-full.jar in in the:
directory.....still no luck, any other suggestions?
If you deploy the .jar file in the lib directory and still don't have luck, then I bet either the .jar is corrupted (which can happen if it's been in CVS or FTPd), permissions issue, or you're not running the default deployment.
Try to run a test program using the .jar file in the lib directory. Also, when you are assembling the .jar file with the EJB, use this sort of ANT jar command:
the .jar would contain lib/comm.jar, for example...
I found the answer at the post below. I was missing saxpath.jar from the classpath and this resulted in the error. Thanks to all for taking the time to look into this.
