OIM9.1.0.1 in Cluster mode installation issue

Question

Hello,
I am facing some issues to setup OIM9.1.0.1 with JBoss Application Server (Cluster mode). After installation of OIM, when I try to start application server, then it is not getting stated. Below are the some initial JBoss AS errors
2008-12-18 12:14:59,625 ERROR [org.apache.commons.digester.Digester] Begin event threw exception
java.lang.ClassNotFoundException: No ClassLoaders found for: org.jboss.web.tomcat.tc5.sso.ClusteredSingleSignOn

2008-12-18 12:15:00,703 ERROR [org.jboss.deployment.MainDeployer] DeploymentException while trying to deploy a package with a new deployer
org.jboss.deployment.DeploymentException: URL file:/C:/thcOIMSetup/jboss-4.2.3.GA/server/all/deploy/jboss-web.deployer/ROOT.war/ deployment failed
The environment details are
•     OIM 9.1.0.1
•     jdk1.6.0
•     JBoss-4.2.3.GA
•     Apache Web Server 2.2
•     Oracle11g
I am referring OIM 9.1.0 documentation; “Deploying in a Clustered JBoss Application Server Configuration“. I am not able to figure out the root cause of the problem. Please provide me some pointer to handle this problem.
Any help would be greatly appreciated!
Regards,

Hi,
I was able to resolve this issue, it looked like the main Tomcat deployer wasn't working i.e. the xlWebApp wasn't getting loaded, infact none of the webapps were getting loaded, i checked it out and found the classloader was trying to load the classes which jboss 4.2.3GA version doesn't even recognize at first place and hence the root.war deployment was failing and which triggered the failure for all the other deployment.
I changed the classloader to load the classes which were right for jboss 4.2.3GA, for e.g.
"org.jboss.web.tomcat.tc5.sso.ClusteredSingleSignOn" to "org.jboss.web.tomcat.service.sso.ClusteredSingleSignOn"
"org.jboss.web.tomcat.tc5.jca.CachedConnectionValve" to "org.jboss.web.tomcat.service.jca.CachedConnectionValve"
after changing this the main tomcat deployer worked and deployed Root.war and after that everything else got deployed.
You can change this by changing these values in the jboss-web.deployer/server.xml or do the custom classloading using a separate custom classloader if you don't want to touch the jboss 4.2.3GA setup after OIM 9101 install.
Thanks
