Problem in deploying EJB to weblogic 8.1 from eclipse

hi,
i have developed an EJB as mentioned in the tutorial of eclipse EJB Development section. I have created a TraderBean and generated the rest of the classes and interface classes and deployment descriptor through XDoclet and deployed the bean through eclipse on bea weblogic, but the problem is, it doesnt deploy the bean with the JNDI name i assigned it in the deployment descriptor, bea weblogic assigns the JNDI name by itself.

I have also developed my client which calls my ejb bean but it couldnt lookup my EJB because it isnt deployed with the JNDI name i gave it.

How can i make the ejb deployed to bea with the my JNDI name?? Below i am attaching the weblogic-ejb-jar.xml and my client lookup methods.

Please reply ASAP

Thanks
Mak
