Hi,
I am wondering what the deployment descriptors for
container-managed entity bean should be like.
Let say I have "classB" inherit from the base class
"classA". Below are the xml files that I come up
with. When I tried to build the jar file then I
got the following errors:
....
....
ERROR: Error from ejbc: No container managed fields were set for CMP bean
classB_ejb
ERROR: Error from ejbc: A valid home interface was not set for bean
classA_base_ejb
My questions are:
(1) Since classB home interface should not inherit from class_A home interface,
isn't that classA should not have a home interface?
(2) Since classB inherits from classA, isn't that classB cmp fields do not
needed to be specified in the ejb-jar.xml file?
Currently I am using Weblogic 5.1.
Any pointers or advice is appreciated.
