Failing to lookup UserManagerHome

Question

Hi,
In BEA portal 8.1. I am trying to call the following snippet on code inside a J2EE servlet filter intercepting any requests to URI /sampleportal.
Hashtable env = new Hashtable();
env.put(javax.naming.Context.SECURITY_PRINCIPAL, "weblogic");
env.put(javax.naming.Context.SECURITY_CREDENTIALS, "weblogic");
return new InitialContext(env);
InitialContext initContext = new InitialContext(env);
_usrManagerHome = (UserManagerHome)
initContext.lookup(ApplicationHelper.getApplicationName() + ".BEA_personalization.UserManager"); -> 1
userManager = usrManagerHome.create();
_userManager.userExists(userName);
The JNDI lookup (1) is failing. I have tried many combinations after studying the samples (CreateUserBacking.java) but nothing worked. Even recompiled the whole portalApp and redeployed it. An interesting thing I observed in weblogic.xml for sampleportal is that the jndi names are prefixed with ${APPNAME}. How does this variable translate to the real Application URI ?
I want to verify the presence of a User id in the local repository for the portal. Is this the right way to do it ?
If so what am I doing wrong ? Any input will be greatly appreciated.
Thanks,

Answer 1

${APPNAME} should get switched the application name for JNDI binding
during deployment. Check in the console to see what's actually in the
JNDI tree (I think you can right-click on your Server in the tree).
You would probably be better off using an <ejb-ref> -- then you would
get deployment time warnings and failures if the EJB didn't deploy
correctly. If it's not there, make an <ejb-ref> entry in web.xml to
<ejb-link>p13n_ebj.jar#UserManager</ejb-link>, then use a JNDI name like
"java:comp/env/<ejb-name from web.xml>"
Also, please attach the stacktrace and any server start output to help
solving this problem.
