Problem using findByPrimaryKey with a CMP Bean

[Tony Evans]

I am currently running the Tutorial for building J2EE Applications using JBOSS and ECLIPSE chapter 6
the tutorial shows you how to create a CMP. One of the methods is findByPrimaryKey.

The problem is that when I call the findByPrimaryKey method :

SupplierLocal supplier = this.suppLocalHome.findByPrimaryKey(suppID);

It returns a null pointer value.

According to the tutorial the findByPrimaryKey is set by the container.

Using a search I can find reference to the findByPrimaryKey in two files:


SupplierHome

public au.com.tusc.cmp.Supplier findByPrimaryKey(java.lang.String pk)
throws javax.ejb.FinderException,java.rmi.RemoteException;


SupplierLocalHome


public au.com.tusc.cmp.SupplierLocal findByPrimaryKey(java.lang.String pk)
throws javax.ejb.FinderException;

But it has not generated any reference to the findByPrimaryKey method in the deployment descriptors.


What I need to know is how to set the findByPrimaryKey method within the deployment descriptors.
Or how to set it up with xdoclet.

Thanks for any help.

Yup ! I have the same problem. I the same code deployed on WebLogic 7.1 and when I print ctx.getPrimaryKey() in ejbPostCreate method, I could get the Primary Key value. However, JBoss is not setting the context properly. However, the row is getting inserted in database with correct sequence value.

BTW, I am using JBoss 4.0 with MySql 5.0. My table has primary key defined as AUTO_INCREMENT column. In my code, I am establishing a CMR relation with another entity bean and JBoss is creating a new Bean of current type (I am guessing it because I could see setEntityContext invoked again) before establishing the relation.
