How do I get myeclipse to write the weblogic specific weblogic-ejb-jar.xml? I am repeatedly getting an error when attempting to compile a weblogic split directory structure via the wlappc ant task. I have verified that my ant script is creating the structure correctly (all the other modules – including other ejb modules – build fine). I created by hand an initial weblogic-ejb-jar.xml file, but there is not alot in it (this is a simple ejb module that contains three session beans). It would appear by the error that something is up with my transaction statements but I think they are correct. Im wondering what the <weblogic/> xdoclet task would do for specific deployment descriptors but do not see where to enable it in the xdoclet project properties settings? So how do I get it to be automatically created?

Thanks in advance,

Scott

The xdoclet generated ejb.xml file is as such:

Ok so I missed the <weblogic/> xdoclet ant task … I have it working now … The null pointer exceptions from wlappc appear to be caused by the myeclipse ejb creation wizard creating one of the interface class names the same as the bean class.

Great, thank you for closing the loop with us.
