EJB - Lookup failed for 'ejb/BookRequestBean'

There can be several reasons to this:

1) Your EJB is not mapped to JNDI name. You need to check whether your EJB is deployed successfully and it is mapped to JNDI name. You can check Server GUI, Server Log on startup or use Universal Test Client to see if EJB is mapped correctly. Note, UTC will only show Remotely exposed EJBs.

2) Your EJB is only exposed to Local application. In this case, Remote call or Cross application call(different EAR, WAR...) to your EJB will fail. In this scenario, create Remote interface and expose it. Local interface exposes EJB to only local calls. Remote interface exposes EJB to remote or cross application calls.

3) Your RMI/IIOP port may be incorrect. You can check Glassfish GUI or Server startup log to see what port RMI/IIOP is assigned to.

Note: To diagnose the exact problem, please post full stack trace.


In addition to nice @RaviTrivedi answer, here are few thoughts:

  • @Named annotation shouldn't be used this way
  • don't use both name and mappedName, for Glassfish it is enough to use just mappedName
  • your EJB should implement remote interface

Adding to @Ravi Trivedi and @Miljen Mikic, if you are using Glassfish, you should check how your EJB is registered in JNDI. In Glassfish for example type the following command:

 asadmin list-jndi-entries
