JboInitialContextFactory synonym error

Question

I am trying to setup up two users with each tablespace. And for each user I want to deploy BC4J components. I then have EJB clients to lookup those BC4J in local mode.
All this is working very fine when using one user. But as soon as I have setup the new user an tablespace, environment etc. it does not work for the first user.
The problem is that I get a ClassCastException when trying to lookup the Application Module.
If I then just executes "loadjava.... -s ..." with the JboInitialContextFactory for the first user, then it works again, but not for the new user now.
So is there anything I can do about this public synonym and AppModule lookup, so I can have two user on my Oracle8I 8.1.6, running BC4J components in both..
Thanks in advance.

Hi Laura!
Here is the stack trace from (bdump):

And the code being executed:
private InitialContext getJboContext() throws NamingException {
if ( this.m_jboContext != null ) {
return this.m_jboContext;
Hashtable env = new Hashtable(10);
env.put( javax.naming.Context.INITIAL_CONTEXT_FACTORY, JboContext.JBO_CONTEXT_FACTORY );
env.put( JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_LOCAL );
this.m_jboContext = new InitialContext( env );
return ( this.m_jboContext );
private ApplicationModule getUserAppModule() throws RemoteException {
if ( this.m_userAppModule != null ) {
this.m_userAppModule.sync();
return this.m_userAppModule;
try {
ApplicationModuleHome userAppHome = (ApplicationModuleHome) getJboContext().lookup( "net.chili.business.user.UserModule" );
this.m_userAppModule = userAppHome.create();
catch ( NamingException e ) {
log.logErr( "getUserAppModule failed...", e );
throw new RemoteException( "getUserAppModule failed: " + e.getMessage() );
return ( this.m_userAppModule );
And it is in the lookup line the exception raises, but before anything can be catched in this code.
