[jboss-user] [Installation, Configuration & DEPLOYMENT] - JBoss 4.0.4: Classloader not found exception when deploying
(JBoss 4.0.4, JDK 1.5)
I have two web applications, which are using the same jar file and are to be deployed on
the same JBoss AS instance. In both cases the jar file will be included in the
WEB-INF/lib, as potentially they will be using different version of the jar file. Both
appplications are running fine when deployed on two different machines. However I have
problems when deploying both WAR files on the same JBoss AS instance: For one particular
command I get a Exception:
1:05:54,114 ERROR [[schedulerServiceExporter]] Servlet.service() for servlet
schedulerServiceExporter threw exception

After reading:
http://wiki.jboss.org/wiki/ClassLoadingConfiguration
http://java2.5341.com/msg/68202.html
I tried several scenarios to solve my problem but neither of these have worked:
1. Set the attribute Java2ClassLoadingCompliance in
JBOSS_HOME\server\default\deploy\jbossweb-tomcat55.sar\conf\jboss-server.xml to a) true
and b) false
2. Add the line to the jboss-web.xml of the first war file:
<loader-repository>com.dns:loader=my-webapp1.war</loader-repository>
and add the line tothe jboss-web.xml of the second war file
<loader-repository>com.dns:loader=my-webapp2.war</loader-repository>
3. Add the lines to both jboss-web.xml:
<loader-repository-config>java2ParentDelegation=false</loader-repository-config>

I am running out of ideas. Did anyone have similar problems and found a work around?
Thanks,
Anette
