Having problems looking up a Seam component in the JNDI ENC

[zzzz8]

I'm running Seam in Tomcat (EJB 3 embedded) and my client program cannot perform the lookup. I'm not sure if I'm missing something in my configuration files. My jndi.properties has the following (which is the default content in the jndi.properties file given in the Seam examples):

java.naming.factory.initial org.jnp.interfaces.LocalOnlyContextFactory
java.naming.factory.url.pkgs org.jboss.naming:org.jnp.interfaces

My stateless session bean is defined like this:

@Name("TestConnection")
@Stateless
public final class TestConnectionBean implements TestConnectionLocal {
...
}

In my client code which is used to lookup the Seam component, I have the following:

TestConnectionLocal connection = null;
try {
 InitialContext ctx = new InitialContext();
 connection = (TestConnectionLocal) ctx.lookup("java:comp/env/ejb/TestConnectionBean/local");
....
}

When I try invoking it from my client code, I get the typical NameNotFoundException error:

javax.naming.NameNotFoundException: Name TestConnectionBean is not bound in this Context

I've noticed the following on startup on the Tomcat console:

INFO 30-09 18:54:08,523 (Component.java:<init>:217) -Component: TestConnection, scope: STATELESS, type: STATELESS_SESSION_BEAN, class: test.TestConnectionBean, JNDI: TestConnectionBean/local

I've tried a couple of different contexts without success:

java:comp/env/TestConnectionBean/local
TestConnectionBean/local
etc...

The Tomcat JMX console (and I'm also using MC4J) don't seem to show the Seam components anywhere... What am I doing wrong? Thanks!

I'm pretty sure Seam components aren't registered in JNDI, EJB3 session beans are though - The JNDI name in the Seam startup refers to this. I would suggest asking on the EJB3 forum about JNDI lookup of EJB3 session beans.

Hi,

This is an old thread but i got the exact same problem. Have you managed to get this working ?

I must say that i'm using Maven2. The following works in JBoss AS but not in the microcontainer :

@Local
public interface Authenticator
{
 boolean authenticate();
}

and

@Name("authenticator")
@Stateless public class AuthenticatorAction
 implements Authenticator
{ ... }

and got

 ... 65 more

Although i also got :

 INFO 2007-04-13 16:58:34,703 (Component.java:245) - Component: authenticator, scope: STATELESS, type: STATELESS_SESSION_BEAN, class: xxx.actions.AuthenticatorAction, JNDI: AuthenticatorAction/local

When i look into jndi from my test class

InitialContext context = new InitialContext();
NamingEnumeration<NameClassPair> enumeration = context.list("java:/");
...

i got only

UserTransaction: org.jboss.tm.usertx.client.ServerVMClientUserTransaction
impDatasource: org.jboss.resource.adapter.jdbc.WrapperDataSource
TransactionManager: org.jboss.tm.TxManager

I tried so much things ... Thanks

I asked the same question in the EJB3 forum a while back and I didn't get a reply there either. I did not make any progress on this issue (and abandoned it). So unfortunately, I can't offer much help...

Anyone from the Seam team ? Please ?

java:comp/env/ejb/TestConnectionBean/local

This just not the right JNDI lookup to get a remote EJB handle. I'm not sure what the right lookup is (definitely not with an ENC prefix) and if the old E-EJB3 container even supports remote JNDI/remote EJBs. I don't think it does.

All of this has not much to do with Seam, though.

[christian.bauer]

The newer Embedded JBoss5 container supports remote EJB/JNDI by the way, check the wiki. Now we only need a release of this and someone who will update all the Seam examples and the testing framework :)

[kosiakk]

@Local interface is redundant now!

just write

@Name("authenticator")
public class AuthenticatorAction
{ ... }

and it will work after Seam2 integration =)
