JNDI Binding

[roby]

Hi
can anyone help me with JNDI binding of reference names and JNDI names of my enterprise beans?
Why my servlet can't find my bean if I use the JNDI name in lookup method? Where I mistake?
I'm novice of JBoss.
Thanks!

Post the detail errors, relevent deployment
descriptors and code snippets.

Most likely you are using the wrong name,
e.g. you didn't define the <ejb-ref>

This is an example of my application:
I have a bean with jndi name ConverterEJB and a Client that in its code use the following call:

Object ref = context.lookup("ejb/SimpleConverter");

how can I bind ConverterEJB with ejb/SimpleConverter??

With J2EE RI we used deploytool to simply make this binding process!!
Exception is:
Caught an unexpected exception!
javax.naming.NameNotFoundException: SimpleConverter not bound

Hi!

Are you sure that the EJB is deployed without errors?

Did you specified the JNDI-Name in the jboss.xml ?
has to look like this:


<ejb-name>SimpleConverter</ejb-name>
<jndi-name>
ejb/SimpleConverter
</jndi-name>
<local-jndi-name>
ejb/SimpleConverterLocal
</local-jndi-name>

Thanks for your response!
I'm resolved my problem, this is my jboss.xml file:

<enterprise-beans>

<ejb-name>ConverterEJB</ejb-name>
<jndi-name>ejb/SimpleConverter</jndi-name>


<ejb-name>ConverterEJB</ejb-name>
<jndi-name>ejb/SimpleConverter35</jndi-name>

</enterprise-beans>



In this way I'm able to run my EJB like "ejb/SimpleConverter", "ejb/SimpleConverter35" ect.
Firstly I don't knowed what files are involved, and what tags...
Excuse-me for my english, I'm Italian!!
Grazie mille

I'm in error...
My old post is not correct...
Only the second jndi-name work well, the first is ignored...
This is yet a result, but it's no possible I can't bind two jndi-names whit an ejb-name, in JBoss!!!
Anyone resolved this problem??

Well...
I don't think that you can give the same Bean 2 JNDI-Names with the jboss.xml (take a look at the DTD).

In fact, I don't think that it is very useful.

If you really want that I think you have to to a workaround and bind it with a selfwritten MBean.

(BTW greetings from Austria to Italy!)

You should be able to do this with 3.2
using the invoker proxy bindings.

You just bind it to the same protocol twice
with different jndi names.

I have the same problem, wanting to assign 2 JNDI names to one EJB.
Could you give a sample how this could be done?

Thank you
