Hi All...
I have a core jar that contains the majority of our business objects as EJB3 entity beans
and some simple EJB3 Stateless DAO beans (see Hibernates suggested DAO pattern - caveat
emptor example/GenericDAO). This is packaged as objectmodel-core.jar
In most cases this jar is packaged in a deployable EAR as an EJB jar, however we have some
applications that use the defined business objects as POJO's and not EJB entity beans
(no usage of @EJB, @Resource or any other type of injection - no usage of persistance
units, entity managers and the like... pure POJO).
In this case we have an application.xml that looks like
<?xml version="1.0" encoding="UTF-8"?>
| <application xmlns="http://java.sun.com/xml/ns/javaee"
| xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
| xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/application_5.xsd"
| version="5">
| <module>
| <web>
| <web-uri>webapp.war</web-uri>
| <context-root>/application-web</context-root>
| </web>
| </module>
|
| <library-directory>lib</library-directory>
| </application>
with objectmodel-core.jar included in the library-directory
On deployment to JBoss 5.0.1.GA i get an exception stating that it can't find
persistence unit named 'null':

There are zero usages of AnswerDAOImpl or its service interface, and absolutely no usages
of any Entity beans save for one single class being used as a simple POJO.
This worked in JBoss 4.2.2.GA so I'm not sure whats going on. IMHO JBoss's
deployment scanner shouldn't be touching this jar at all as its not referenced by the
application.xml ...
Anyone have any idea's whats going on here? how can I deploy this application without
JBoss attempting to deploy the persistance unit (i've tried removing all
persistence.xml and like configuration files from the jar - no dice).
Thanks for your help.
