Can you post your ejb-jar.xml deployment descriptor? If it contains an
EJB reference to the EJB (best practice), then
you should have a mapping in WAS between this reference (which you use to do your JNDI lookup) and the actual JNDI name of the referenced bean. If there is no EJB reference, then you must lookup the real JNDI name that the EJB is bound to. I am not knowledgable about WAS, but I think you will find the JNDI names of EJBs are stored in the bindings file named ibm-ejb-jar-bnd.xmi under the directory META-INF.
