Creation error of EJB

Former Member · ‎06-04-2007

Hi!

I ran into the following problem when referencing the public parts of

an external j2ee library project stored in the NWDI. Specifically I would

like to reference an API part for having a correct build path during development.

Unfortunately I can create this reference but afterwards the NWDS tells

me that it requires to rebuild the ejb-jar.xml and the ejb-j2ee-engine.xml.

This automated refactoring leaves me with two 'empty' files, having all

my ejb definitions removed.

I tried to define new stateless ejbs by creating them via the context menu

and ran into the error 'Not able to create Session Bean'. In order to find out

what happened, I checked the .log file of the NWDS in my workspace folder

and found the following lines:
