Similar issue with persistence units - if two ears (say, test1.ear and test2.ear) include
the same ejb jar (with same META-INF/persistence.xml), you get

application.xml (identical in test1.ear and test2.ear):
<application>
| <display-name>Test Application</display-name>
|
| <module>
| <ejb>TestEjb.jar</ejb>
| </module>
|
| </application>
|
persistence.xml (in TestEjb.jar's META-INF):
<?xml version="1.0" encoding="UTF-8"?>
| <persistence version="1.0"
| xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
| xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
| <persistence-unit name="TestEjb">
| <provider>org.hibernate.ejb.HibernatePersistence</provider>
| <jta-data-source>java:/TestDatasource</jta-data-source>
| <properties>
| <property name="hibernate.dialect"
value="org.hibernate.dialect.HSQLDialect" />
| </properties>
| </persistence-unit>
| </persistence>
|
Although the JNDI View shows both persistence units:
+- persistence.unit:unitName=test2.ear (class: org.jnp.interfaces.NamingContext)
| | +- TestEjb.jar#TestEjb (class: org.hibernate.impl.SessionFactoryImpl)
| ...
| +- persistence.unit:unitName=test1.ear (class: org.jnp.interfaces.NamingContext)
| | +- TestEjb.jar#TestEjb (class: org.hibernate.impl.SessionFactoryImpl)
|
