Hi

I am usign a session bean to access my entity bean

But I am getting
javax.naming.NameNotFoundException: No object bound to name java:comp/env/ejb/ForumBean

I am using the deploytool for deploying there is no option to set a JNDI name for Local Entity bean . Is it required to set a JNDI name for the local entity bean ?

My look up code is

Context initial = new InitialContext ();
(ForumHome) initial.lookup ("java:comp/env/ejb/ForumBean
");

My xml files are

hi

from your code in sun-ejb-jar.xml JNDI name for ForumBean was missing

<sun-ejb-jar>
<enterprise-beans>
<name>ForumJar</name>
<ejb>
<ejb-name>ForumBean</ejb-name>
<jndi-name>ForumBean</jndi-name> <!-- MISSING -->
</ejb>
<ejb>
<ejb-name>AccessForumBean</ejb-name>
<jndi-name>AccessForumBean</jndi-name>
</ejb>
<cmp-resource>
<jndi-name>MSG_DB</jndi-name>
</cmp-resource>
</enterprise-beans>
</sun-ejb-jar>

Hi

I have given the jndi name and deployed . This is the sun-ejb-jar file after deployment . Still I am getting the error

at org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:542)
at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:647)
at java.lang.Thread.run(Thread.java:536)
Caused by: java.rmi.RemoteException: ; nested exception is:
javax.naming.NameNotFoundException: ForumBean not found
Caused by: javax.naming.NameNotFoundException: ForumBean not found



My code is

public Forum createForum (String forumTitle, String forumDesc, int userId) throws CreateForumException,CreateException,RemoteException,NamingException
{
ForumHome home = getForumHome ();
return home.create (forumTitle,forumDesc,userId);
}

private ForumHome getForumHome ()throws NamingException
{

Context initial = new InitialContext ();
return (ForumHome) initial.lookup ("ForumBean");


}
