    NullPointerException deploying JPA web application at jboss-

    Manuel Monjo Newbie

      I developped a web applicacion using JPA as persistence technology and spring-framework-3.0.0.M2 under jboss-5.0.0.CR1 and everything seems to work fine with no problem at all.

      The problem comes when I try to deploy the war file to any of the later versions jboss-5.0.0.CR2, jboss-5.0.0.GA, jboss-5.0.1.GA.

      I always get a NullPointerException caused at deployment time.

      Here is the stack trace from version jboss-5.0.1.GA:

      The persistence.xml file located at directory WEB-INF\classes\META-INF looks like this:

      <?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="UNITNAME" transaction-type="RESOURCE_LOCAL">
       <provider>org.hibernate.ejb.HibernatePersistence</provider>
       <jta-data-source>java:comp/env/jdbc/MySqlDS</jta-data-source>
       <class>Class1</class>
       <class>Class2</class>
       ...
       <class>ClassN</class>
       <properties>
       <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
       <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
       </properties>
       </persistence-unit>
      </persistence>

      I did not find anything in release notes referenced to the way of deployment of JPA web applications.

      Has anyone else experienced this case?
      Any suggestion?

      Many thanks.
