PersistenceUnitLoadingException after setting up Eclipselink

[seifert]

I followed the How to use EclipseLink with AS7-Tutorial ( https://community.jboss.org/wiki/HowToUseEclipseLinkWithAS7#/?page=2 ) to setup JBoss 7.1.1.Final to use Eclipselink 2.5.0:

<dependency>

          <groupId>org.eclipse.persistence</groupId>

          <artifactId>org.eclipse.persistence.jpa</artifactId>

          <version>2.5.0</version>

</dependency>

Now I am getting the following errors:

This is what my persistence.xml looks like:

<?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"

                              <property name="eclipselink.weaving" value="static"/>
                       </properties>
          </persistence-unit>
</persistence>

I would appreciate any effort to help.

I would try with WildFly 8 (http://www.wildfly.org/download/ has Alpha4 available now).  There is a pre-built WF8/modules/system/layers/base/org/eclipse/persistence/main folder that already contains the module.xml and jipijapa-eclipselink integration jar.  You just need to add the actual EclipseLink jars to this same folder and update the module.xml to list the added jars.

The only hack that is needed, is that the -Declipselink.archive.factory=org.jipijapa.eclipselink.JBossArchiveFactoryImpl needs to be hacked into the application startup scripts.

Thank you for your answer.

I really would like to stick with my current JBoss. Is this so hard to do with my version?

Moreover I do not dare to use an alpha version...

It sounds like your missing an EclipseLink class dependency in your (org.eclipse.persistence) module.xml that you created for the EclipseLink jars.

Also, if you would like the latest bug fixes for JBoss AS 7.x, switch to EAP 6.x.  Although, it doesn't sound like your hitting a bug yet.

[seifert]

my module.xml looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="org.eclipse.persistence">
 <resources>
  <resource-root path="org.eclipse.persistence.jpa-2.5.0.jar"/>
 </resources>
 <dependencies>
  <module name="asm.asm"/>
  <module name="javax.api"/>
  <module name="javax.persistence.api"/>
  <module name="javax.transaction.api"/>
  <module name="javax.validation.api"/>
  <module name="javax.xml.bind.api"/>
  <module name="org.antlr"/>
  <module name="org.apache.commons.collections"/>
  <module name="org.dom4j"/>
  <module name="org.javassist"/>
  <module name="org.jboss.logging"/>
 </dependencies>
</module>

[smarlow]

Did you check that the org.eclipse.persistence.jpa-2.5.0.jar file is in the $JBOSS_HOME/modules/org/eclipse/persistence/main folder?  Sometimes people download EclipseLink and the naming is a little different.

Also, verify that class org.eclipse.persistence.exceptions.PersistenceUnitLoadingException is in the

org.eclipse.persistence.jpa-2.5.0.jar file (jar tf org.eclipse.persistence.jpa-2.5.0.jar | grep org.eclipse.persistence.exceptions.PersistenceUnitLoadingException).

.


[seifert]

The naming is fine, but there is indeed no org.eclipse.persistence.exceptions.PersistenceUnitLoadingException in the JAR. Shouldn't Eclipselink ship all it needs? I am still clueless how this is to be solved.

UPDATE:

I was using the wrong JAR for my architecture: With

<dependency>

          <groupId>org.eclipse.persistence</groupId>

          <artifactId>eclipselink</artifactId>

          <version>2.4.2</version>

</dependency>

it works fine now.

Thank you very much for your help!
