jboss gives NoClassDefError for jdom/Text when accessed thro

md81077 Mar 1, 2006 12:48 AM

I have developed a application for our organisation which works fine when accessed through a browser. We also have provided an API (called HTTP API) which is used by java clients to access the system.
I am getting the error NoClassDefError for JDOM/ Text.

I am using JBoss 4.0.2.
Same code is working fine on Jboss 4.0.0.

Please Help
Thanks in advance.

did you add jdom.jar to your war/ear which you deploy on jboss?

In jboss 4.0.2 jaxen.jar is part of the bootstrap libraries. This has been changed for version 4.0.3 http://jira.jboss.com/jira/browse/JBAS-1970

Putting jdom.jar in your war/ear might not be enough if classes from within jaxen.jar are trying to access jdom classes.

Jboss class loading http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossClassLoadingUseCases Gives a good description of what happens with external libraries that are packed as part of your war and the scope of loading classes.

I solved the problem by placing jdom.jar in $JBOSS_HOME/lib and then loading the jar at boot time by placing '-L jdom.jar' in my run.sh as a command line argument, similarly to http://www.jboss.org/?module=bb&op=viewtopic&p=3830976. I hope this helps.
