[jboss-user] [Installation, Configuration & DEPLOYMENT] - Problem deploying 2 persistence units in 2 EJBs in an EAR

[anb@beyondfibre.tv]

Hello all

We have a problem depoying a J2EE project under Jboss AS 4.2.2

There is an EAR project with two EJBs JAR with their own entities and persistence unit. The 2 persistence.xml files are in the META-INF directories of the EJBs' JAR and they bind to two different data stores defined in a *-ds.xml file.

Here is the ds file: (deployed directly in server/default/deploy/ )

	<local-tx-datasource>
      <jndi-name>firstDatasource</jndi-name>
      <connection-url>jdbc:mysql://localhost:3306/sometable</connection-url>
      <driver-class>com.mysql.jdbc.Driver</driver-class>
      <user-name>user</user-name>
      password
   </local-tx-datasource>
   <local-tx-datasource>
      <jndi-name>secondDatasource</jndi-name>
      <connection-url>jdbc:mysql://localhost:3306/someothertable</connection-url>
      <driver-class>com.mysql.jdbc.Driver</driver-class>
      <user-name>user</user-name>
      password
   </local-tx-datasource>


Then the persistence.xml files:

<persistence-unit name="second"  transaction-type="JTA">
   org.hibernate.ejb.HibernatePersistence
   <jta-data-source>java:/secondDatasource</jta-data-source>
   
      
      
      
      
      
   
</persistence-unit>

...

<persistence-unit name="first"  transaction-type="JTA">
   org.hibernate.ejb.HibernatePersistence
   <jta-data-source>java:/firstDatasource</jta-data-source>
   
      
      
      
      
      
   
</persistence-unit>

However when the project is deployed we are getting the following error :

08:44:31,692 WARN  [ServiceController] Problem starting service persistence.units:ear=ourproject-ear.ear,jar=ourejb.jar,unitName=second
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial

	at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
	at java.lang.reflect.Method.invoke(Method.java:597)
	
	
Following this error message we investigated the initial context parameters in the conf folder, and jndi.properties seems to be fine (default values):

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces

Any help would be gladly appreciated !
