In jboss specific file I do not find this kind of information. So I am not sure the 2 tables will be joined. Could some body explain me.
Partical content of weblogic file is given below.
Thanks.

Yes this is more advanced configuration. The final version of book will have more info on this. Until then, buy the JBoss CMP 2.0 docs from the website.

I have just tried this example on jboss-3.2.2RC4 and it
fails to deploy complaining about the CustomerBean not having a local-home. Defining CustomerLocal and CustomerHomeLocal does the trick! But why does it need these interfaces to be defined?

Hello!

I have the exact same problem!
The erros code is:
org.jboss.deployment.DeploymentException: CustomerEJB has no local home interface.

Greetings,

How do you write the CustomerHomeLocal interface?
And with what methods?

Thanks

I hope that some of the authors of the book might answer to this problem.
Indeed, exercise 6.3 does not deploy correctly in JBoss 3.22, unless you define a local and a local home interface for Customer Bean.
But from the point of view of the bean developer, there is no "obligation" to define such local interfaces.
Customer has both remote interfaces (remote and home) such that a remote client can have access to it.
Address Bean has the proper local interfaces and Customer uses it properly.
But nowhere is written that maybe the CMP Engine might need local interfaces for Customer Bean, to be able to join both tables.
That is what I want to know. I have read the full CMP Engine documentation for JBoss 3.22, and nothing is there concerning this problem.

Again the problem is not how to write the local interfaces for Customer Bean. If you write them down everything works fine. THE PROBLEM IS WHY SHOUD YOU WRITE SUCH LOCAL INTERFACES FOR CUSTOMER BEAN.

Perhaps 3.2.3 will fix it???
