How do I run findByPrimaryKey method with CMP 2.0?

[alzamabar]

Hi, I'm deploying a local entity bean. I know that I can run any finder method with CMP 2.x by declaring it as abtract in the bean implementation class and then by defining the query in the deployment descriptor. My question is: how do I run the findByPrimaryKey method? Shall I write a query element in the dd? How do I execute it from the client?
Regards,
Marco

Hi,
Here is a complete and basic tutorial on ejb ql -

The Container provides an implementation of ejbFindByPrimaryKey() for each CMP Bean without additional work on the part of the Bean Developer. All you have to do (and are required to do) is include an ejbFindByPrimaryKey method in your CMP's local home or remote home interface. This of course is assuming you got all the CMP deployment descriptor jazz correct.
To use the findByPrimaryKey method you just need to lookup the home interface and call findByPrimaryKey(). It would look similar to the following (ExampleHome and Example are the local home and local interfaces the the ejb)...

Context context = new InitialContext();
ExampleHome home = (ExampleHome)context.lookup("local.home.jndi.name");
Example = home.findByPrimaryKey(pk);
