Error in deployment of ejbmodule

Question

Hi folks,
I'm trying to start a GP process from a CAF Application Service. I have followed the follwing tutorial <a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/43/fcdf77fc6510b3e10000000a11466f/frameset.htm">Starting GP Process</a>.
Here is my Code Snipplet:
public boolean startProcess() throws com.sap.caf.rt.exception.ServiceException {
        // logging
        java.lang.String CAF_user = sessionContext.getCallerPrincipal().getName();
        java.lang.String CAF_methodHeader = CoordinationServiceASBean.JARM_REQUEST + ":" + "startProcess()";          
        Object[] CAF_parameters = new Object[] {};
        com.sap.caf.rt.util.CAFPublicLogger.entering(CAF_user, CoordinationServiceASBean.JARM_REQUEST, CAF_methodHeader, CoordinationServiceASBean.location, CAF_parameters);
          boolean retValue;
          try {
//@@custom code start - startProcess()
               retValue = false;
               //               obtain the process template
               try{
               IUser user = UMFactory.getUserFactory().getUser("test");
               IGPProcess process =
                    GPProcessFactory.getDesigntimeManager().getActiveTemplate("7F727F90E04F11DB9FA0000C2931A604",user);
               IGPRuntimeManager rtm = GPProcessFactory.getRuntimeManager();
               IGPProcessRoleInstanceList roles = rtm.createProcesRoleInstanceList();
               int rolenum = process.getRoleInfoCount();
               for (int i = 0;i< rolenum; i++){
                    IGPProcessRoleInstance roleInstance = roles.createProcessRoleInstance(process.getRoleInfo(i).getRoleName());
                    roleInstance.addUser(user);
                    roles.addProcessRoleInstance(roleInstance);
               IGPStructure params = GPStructureFactory.getStructure(process.getInputParameters());
               String hi = "hi";
               rtm.startProcess(process,"test","testdesc",user,roles,params,user);
               retValue = true;
               }catch(UMException ue){
               }catch(GPInvocationException e){
               }catch(GPEngineException e){
//@@custom code end - startProcess()
             return retValue;
        } finally {
            com.sap.caf.rt.util.CAFPublicLogger.exiting(CAF_user, CoordinationServiceASBean.JARM_REQUEST, CAF_methodHeader, CoordinationServiceASBean.location, CAF_parameters);
I've added the the Public Part external caf/eu/gp/api to my ejbmodule. I have also no build errors in the CAF Project, but when I try to deploy the project the deployment of the ejbmodule fails.
In my sdm logfile I can see the following stacktrace:
ERROR: Not updated. Deploy Service returned ERROR:

                     Reason: Exception during generation of components of application xxxx.com/hello~test in container EJBContainer.; nested exception is:

The deployment fails because of the java.lang.NoClassDefFoundError. He doesn't finds the GP Api.
I'm new to CAF and j2ee development, so can anyone say me how i can solve this error ?
Any help is appreciated.

Hi,
You need to add the GP API DCs as used DC to your development component. To get the GP APIs for local development using NWDS refer these documents:
