SAP NWCE Sneak Preview - Issue with Local DC's

[sid-desh]

Hi,

I am trying to build a demo application with components as local dc's. I will list down the steps and also the problems that i have encountered.

1. I created an EAR Local DC with compliance type equal to Java EE 5.

2. I then created an EJB local DC with the same compliance level.

<u><b>Issue</b></u> - While creating the EJB DC there is no step in the wizard which asks whether the project should be added to EAR DC. Is this the default behaviour. Even the context menu for EJB DC does not have any option which states add to EAR project.

3. In the EAR DC after selecting the option for Add/Remove (context menu option for folder Modules) i added the EJB DC in J2EE Module Dependency option.

4. I triggered a DC build for EJB and EAR DC. The EAR DC build is failing. The build.log file is given below this message.

5. In the EJB DC i generated one entity from the database table after adding persistence. The class file is created correctly, however the entry under the Entity Beans node under Deployment Descriptor is not available. This is not available even after i rebuilt the EJB DC.

Please do let me know if there is a certain step that i have missed.

Thanks and Regards

Sidharth Deshpande

Hi Sidharth,

I usually do it in the following order:

1.Create the EJB DC

2.Create the EAR DC. The wizard of this kind of DC proposes you to add the EJB DC.

3.Create the entities. Its normal that doesn’t appear under the Entity Beans node because this is an EJB 3.0 Entity.

4.Create the Session Bean Service, to expose the business logic methods[/code].
