Unable to deploy custom adapter module in PI 7.31

Hi pros,

I created a custom adapter module to split some complex input files to multiple messages. We use a SAP PO 7.31 java-only installation. I followed this document to create my adapter module:

How to Create Modules for the JEE Adapter Engine

I know it is for PI 7.1 but a colleague of mine said that he was able to create a running adapter module for PI 7.3 following the guide. I created the following projects:

EAR project references the EJB project:

Project facet of the EJBproject:

ejb-jar.xml config:

application-j2ee-engine.xml (in EAR project):

When I try to deploy my module, I get the following error:

Java version:

NWDS version:

Any hint is appreciated! What can be wrong? What can I check again?

Hi Stefan

You did not indicate the SP and patch version your PO 7.31 is on. Is it also on SP12 patch 4? Always best to use the same SP and patch level for NWDS that matches your PO version.

On another note, since you are on 7.31, you can develop the module using EJB 3.0 bean. The steps in the following blog are updated for EJB 3.0 and also the screenshots are more relevant to the newer version of NWDS. I've followed this blog and developed and deployed modules perfectly without an issue.
