Failed to start service jboss.persistenceunit inside EAR

[figwam]

Hi @ll,

after spending many hours and reading forums, I hope for your help:

I have persistence a module, let say persistence-module.jar

persistance.xml inside META-INF

<?xml version="1.0" encoding="UTF-8"?>

<persistence version="2.0"

   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_2_0.xsd">

          <persistence-unit name="myUnit">

                    <jta-data-source>java:/myUnit.dbsource</jta-data-source>

          </persistence-unit>

</persistence>

A class AccountDb.java

@Entity

@Table(name = "ACCOUNT")

public class AccountDb{...}

Now the problem

1.

If I deploy the module.jar inside WAR file, the deployment works fine! I can also persist

the Entity using EnitiyManager.

2.

If I deploy the module.jar inside EAR file (the persistence-module.jar is in the root of EAR), the deployment fail with:

ERROR [org.jboss.msc.service.fail] (MSC service thread 1-3) MSC00001: Failed to start service jboss.persistenceunit

Caused by: java.lang.ClassNotFoundException: com.model.AccountDb from [Module "deployment.module.ear.persistence-module.jar:main" from Service Module Loader]

But the class is inside the jar file, this must be a class loading problem.

After reading this article: https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7

a.) I tried to add a dependency to META-INF/MANIFEST.MF

Manifest-Version: 1.0

Class-Path:

Dependencies: deployment.module.ear.persistence-module.jar export

b.) I also tried to disable isolated deployment:

<subsystem xmlns="urn:jboss:domain:ee:1.0" >           

  <ear-subdeployments-isolated>false</ear-subdeployments-isolated>

</subsystem>

c.) I put beans.xml into META-INF of the persistence-module.jar

META-INF/application.xml (generated by maven EAR plugin v2.6) of EAR looks like:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE application PUBLIC

          "-//Sun Microsystems, Inc.//DTD J2EE Application 1.3//EN"

          "http://java.sun.com/dtd/application_1_3.dtd">

<application>

  <display-name>module</display-name>

  <description></description>

  <module>

    <ejb>persistence-model.jar</ejb>

  </module>

</application>

But still the same error occur

What do I wrong in case 2?

many thx

Try moving persistence-module.jar into your ear/lib folder.

Hi Scott,

thx for your reply! If i put persistence-module.jar inside the lib, the JAR is not

loaded as EJB module, therefore Beans are not loaded (@Entity etc. Annotations are ignored).

As i know the lib-folder is only for common-libs/frameworks, which are not inside

Jboss module folder (such as seam-sold).

Any other idea?

regards

Does you persistence-module.jar contained any session/MDB's? or Just classes with @Entity annotation? If it doesn't have any session/MDB's it's not an ejb module & hence can safely moved to ear/lib directory. The  you should remove it from your application.xml as ejb module.

Also, could you please check name of your jar? your application.xml says "<ejb>persistence-model.jar</ejb>" whereas your name of jar seems to be "persistence-module.jar".

Now I could solve the problem:

1. I moved persistence-module.jar into the module.ear/lib folder

Many thx @Scott & Prasad
