Problem with building EJB with inheritance

Question

I've created a EJB project in my workshop 8.1.4 application.
Since all my tables contains a common subset of columns, I'd like to create a superclass for all CMP entity beans which contains the handful of CMP fields and business methods pertaining to them.
I tried to do it in Workshop by creating a new superclass (BaseEB.java) which extends GenericEntityBean class.
When building, the script tries to run ejbgen on BaseEB.java, which obviously fails because BaseEB does not contain all the required @ejbgen tags, as it is not meant to be used by itself.
I think the solution is a matter of making the build script bypass BaseEB.java, but how can that be done?.

Answer 1

This is my base EJB. There are some @ejbgen tags defined, but it does not have all required ejbgen tags, especially in the class javadoc. The classes that extends from this are expected to define them.
package occ;
import java.util.*;
import weblogic.ejb.GenericEntityBean;
public abstract class BaseEB extends GenericEntityBean
      * @ejbgen:local-method
     public void touch(String username){
          java.util.Date currDate = new Date();
          setUpdateDateTime(currDate);
          setUpdateUsername(username);
          setUpdateTimeID(new Long(getUpdateTimeID().longValue() + 1));
      * @ejbgen:local-method
     public void setCreateBy(String username){
          java.util.Date curr = new Date();
          setCreateUsername(username);
          setCreateDateTime(curr);
          setUpdateUsername(username);
          setUpdateDateTime(curr);
          setUpdateTimeID(new Long(1));
      * @ejbgen:cmp-field column = "UPDATEDATETIME"
      * @ejbgen:local-method
     public abstract void setUpdateDateTime(Date val);
      * @ejbgen:local-method
     public abstract Date getUpdateDateTime();
      * @ejbgen:cmp-field column = "UPDATEUSERNAME"
      * @ejbgen:local-method
     public abstract void setUpdateUsername(String val);
      * @ejbgen:local-method
     public abstract String getUpdateUsername();
      * @ejbgen:cmp-field column = "CREATEDATETIME"
      * @ejbgen:local-method
     public abstract void setCreateDateTime(Date val);
      * @ejbgen:local-method
     public abstract Date getCreateDateTime();
      * @ejbgen:cmp-field column = "CREATEUSERNAME"
      * @ejbgen:local-method
     public abstract void setCreateUsername(String val);
      * @ejbgen:local-method
     public abstract String getCreateUsername();
      * @ejbgen:cmp-field column = "UPDATETIMEID"
      * @ejbgen:local-method
     public abstract void setUpdateTimeID(Long val);
      * @ejbgen:local-method
     public abstract Long getUpdateTimeID();
