Based on your ejb-jar.xml file:
<ejb-jar>
<description>Lek med beans</description>
<display-name>TestAvBeans</display-name>
<enterprise-beans>
<session>
<ejb-name>parfo.Hello</ejb-name>
<home>parfo.HelloHome</home>
<remote>parfo.Hello</remote>
<ejb-class>parfo.HelloBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Bean</transaction-type>
</session>
</enterprise-beans>
</ejb-jar>
>From a client application (note the *client*), you would get a reference to
the the EJBHome using:
Object boundObject = context.lookup("parfo.Hello");
HelloHome helloHome = (HelloHome)PortableRemoteObject.narrow(
boundObject, HelloHome.class);
That is assuming that you don't override the jndi name for the bean in a
jboss.xml file. I don't believe it is spec-compliant (IIRC) to use the
<ejb-name> as the jndi-name, but jBoss does so as a simplification step.
Other servers require you to specify the jndi name for a bean in another
"proprietary" deployment descriptor. For jBoss, this proprietary file is
called jboss.xml:
<jboss>
<enterprise-beans>
<session>
<ejb-name>parfo.Hello</ejb-name>
<jndi-name>parfo/Hello</jndi-name>
</session>
</enterprise-beans>
</jboss>
With this file deployed with your bean, your lookup code would be changed
to:
Object boundObject = context.lookup("parfo/Hello");
So, perhaps you tried all of these options and it still doesn't work.
Perhaps there is a subtle setup error, configuration error, or a bug in the
product. Don't know. I have always used slashes to separate my naming
contexts, but many people use periods as you have. I can't imagine that this
is the source of a bug.
