I'm implementing a security proxy for my entity bean named NodeBean.
I want to check the permissions a user has over a node.
In the security proxy, I am trying to bind to the PermissionBean using the code above:

InitialContext ic = new InitialContext();
PermissionHome permHome = (PermissionHome) ic.lookup("java:comp/env/ejb/PermissionLocalHome");
permHome.findByUserAndNodeId((Integer)ctx.getPrimaryKey(),new Integer(caller));

but it throws:
javax.naming.NameNotFoundException: PermissionLocalHome not bound

the jboss.xml section for the PermissionBean is:

<ejb-name>PermissionBean</ejb-name>
<local-jndi-name>ejb/PermissionLocalHome</local-jndi-name>


can anyone help? how can i obtain a reference to the PermissionBean Home Local interface?
