Accessing EJB from Java Mapping

[Former Member]

Hi all,

I developed an EJB, deployed it to the J2EEServer via Visual Administrator. When I do a lookup from outside (NWDS) with the JNDI Name I gave it, everything works fine.

Now I have to use this EJB in a Java Mapping. I do the same --> lookup and narrow with PortableRemoteObject and so on.

But the problem is that I always get an java.lang.NoClassDefFoundError for the home interface.

Any ideas?

Thanks a lot

Olli

It is not possible to call EJBs from mapping. Could you provide the code of the EJB as a library that you access direct from the mapping instead?

Hello.

Check my wiki article:

Hi Oliver,

Did you imported the EJB classes into the .jar file in Integration Repository -> Imported Archives?

Hi,

yes I did. And now I get a ClassCastException, but with the same implementation as in my remote test.

Could you send the java code and message error implemented in your java mapping?
