NoClassDefFoundError and DeploymentException

karanmg Nov 21, 2005 9:35 PM

My EJB skills are not really the best, and I am trying to deploy this application written by someone else on JBoss AS 4.0.3SP1.
The system is running Windows XP with JDK 1.5_05. If someone could help me out with getting this setup, it would be really great, as I have already spent a considerable time trying to solve the problem. I'm positive its going to be something simple. I am facing the following errors:

I know people have faced this problem before and its probably something very simple. I looked into jbossweb-tomcat55.sar and in META-INF/jboss-service.xml is this:

<attribute name="Java2ClassLoadingCompliance">false</attribute>
<attribute name="UseJBossWebLoader">false</attribute>

Please let me know if you need more info.
Thanks.

Is there no one out there with a solution or at least a hint of a solution to this problem????

My guess is that JBoss can't find this exception class during EJB deployment even though it is in your WAR file. (btw: jars are deployed before wars)

Solution: pull out your Exception class and all other classes which are used in both war and jar into a separate jar file which you include in your ear and adjust the CLASSPATH in your Manifest files to refer to this "shared jar".
