Re: [jboss-as7-dev] Question about EAR's and Class Loading

BTW we've been discussing this one - I think we're going to set it up so
that manifest Dependencies at the EAR level are copied into their
constituent deployments, since this is probably what users will expect
will happen ("export" has certain potentially undesirable side-effects
with regards to class-path references between deployment units). So
expect the "export" to be no longer necessary in Beta2.
So, after getting past that, and successfully creating a module for
MySQL and defining my data source, I know have another interesting
issue with my ear file.
I get the following:
Caused by: java.lang.ClassNotFoundException:
services.entities.Product from [Module
"deployment.OrderManagerApp.ear.OrderManagerEJB.jar:main" from
Service Module Loader]
So, my ear is constructed in a fairly simple manner, and the same as
it was for AS 5/6. I have an OrderManagerEntities.jar that has the
entities in them, including the services.entities.Product that its
complaining about, and that jar is in the ear, but the stateless
session beans in OrderManagerEJB.jar reference it. It appears that
there is not proper visibility to the entities in the other jar of
the ear, and it cannot find it.
If OrderManagerEntities.jar is in the EAR's "lib" directory (or the
directory you have configured as such in application.xml) then the
OrderManagerEJB.jar should be able to "see" it. If not then you'll need
an explicit "Class-Path" reference to it from your EJB JAR.
