NW04s SP09: EJB calling GP APIs throws exception

[Former Member]

Hi all,

I have created an EJB project which has a stateless session bean that calls the GP APIs to start a process. I have added the GP jars "sap.com_cafeu_gpapi~external.jar" to the build path of this EJB project. It builds and deploys fine but when I try to call the bean method, it throws an exception saying "java.lang.NoClassDefFoundError: com/sap/caf/eu/gp/process/dt/impl/GPDesigntimeManager". Where am I going wrong? What is the correct procedure to add the GP libraries to an EJB project?

Regards,

Satyajit.

Following needs to be done for this.

1) Go to EJB perspective of NWDS.

2) Select Navigator View

3) Expand project and browse to META-INF --> application-j2ee-engine.xml file

4) Click on the file to open it on right pane.

5) Select the references , and click on Add ( at the bottom)

6) Select Create New

7) Add the following entry

Reference Target : caf_eugp~api

Reference Type : weak

Reference Target Type : library

Provider Name : sap.com

😎 Compile , Deploy and Test.

Thanks,
