[b]EJB2.0 entity bean must not be an abstract class?!!![/b]

[vvinjamur]

Hi,

please suggest


I am trying deploy an example application for CMP

as it is mentioned that the container will implement the entity class and we need to make the entitybean class as an abstract class i did the same but to my frustration while deplying it is giving the following warning
**********************************************************
Bean : ProductEBean
Section: 9.2.2
Warning: The entity bean class must not be defined as abstract.

16:41:59,031 INFO [EJBDeployer]
Bean : ProductEBean
Section: 9.4.7.1
Warning: The primkey-field element must name a public field in the bean implementation class.

********************************************************
and at run time it gives an exceptoin like this:
*********************************************************

17:00:43,359 ERROR [STDERR] java.rmi.ServerException: Could not instantiate bean; nested exception i
s:
java.lang.InstantiationException: examples.ejb.ProductEBean; nested exception is:
java.rmi.ServerException: Could not instantiate bean; nested exception is:

17:00:43,359 ERROR [STDERR] java.rmi.ServerException: Could not instantiate bean; nested exception i
s:
java.lang.InstantiationException: examples.ejb.ProductEBean

**********************************************************

I am clue less as to why is saying as the class must not be abstract even though i mentioned

<persitence type> as Container in ejb-jar xml

please help

Hi,
it looks like JBoss expects CMP 1.x.
Check ejb-jar.xml if there is element
<cmp-version>2.x</cmp-version> in entity bean definition.
See ejb-jar_2_0.dtd for more details.

No the problem is you have not declared the EJB 2.0 doctype. If you do not have the doctype declaration, which is required by the EJB spec, you get EJB 1.1. The EJB 2.0 doctype follows:[pre]
<!DOCTYPE ejb-jar PUBLIC
"-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN"
"http://java.sun.com/dtd/ejb-jar_2_0.dtd"> [/pre]
