[jboss-user] [JBoss Seam] - Re: What's wrong with this components.xml / persistence.xml

[mlh496]

Here is my persistence.xml file:

<persistence>
  |     <persistence-unit name="omegaFactory">
  |         <provider>org.hibernate.ejb.HibernatePersistence</provider>
  |         <jta-data-source>java:/omegaDatasource</jta-data-source>
  |         <properties>
  |             <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>
  |             <property name="hibernate.transaction.flush_before_completion" value="true"/>
  |             <property name="hibernate.show_sql" value="true"/>
  |             <property name="jboss.entity.manager.factory.jndi.name" value="java:/omegaDatasource"/>
  |             <property name="hibernate.cache.provider_class" value="org.hibernate.cache.HashtableCacheProvider"/>
  |             <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
  |         </properties>
  |     </persistence-unit>
  | </persistence>

And here is my jboss-beans.xml file:

<?xml version="1.0" encoding="UTF-8"?>
  | 
  | <deployment xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  |             xsi:schemaLocation="urn:jboss:bean-deployer bean-deployer_1_0.xsd"
  |             xmlns="urn:jboss:bean-deployer:2.0">
  | 
  |     <bean name="omegaDatasourceBootstrap" class="org.jboss.resource.adapter.jdbc.local.LocalTxDataSource">
  |         <property name="driverClass">com.mysql.jdbc.Driver</property>
  |         <property name="connectionURL">jdbc:mysql://localhost:3306/omega</property>
  |         <property name="userName"><value class="java.lang.String">username</value></property>
  |         <property name="password"><value class="java.lang.String">password</value></property>
  |         <property name="jndiName">java:/omegaDatasource</property>
  |         <property name="minSize">0</property>
  |         <property name="maxSize">10</property>
  |         <property name="blockingTimeout">1000</property>
  |         <property name="idleTimeout">100000</property>
  |         <property name="transactionManager"><inject bean="TransactionManager"/></property>
  |         <property name="cachedConnectionManager"><inject bean="CachedConnectionManager"/></property>
  |         <property name="initialContextProperties"><inject bean="InitialContextProperties"/></property>
  |     </bean>
  |     
  |     <bean name="omegaDatasource" class="java.lang.Object">
  |         <constructor factoryMethod="getDatasource">
  |             <factory bean="omegaDatasourceBootstrap"/>
  |         </constructor>
  |     </bean>
  | </deployment>

When I turn logging to debug, this seems to be the error that starts it all:

Caused by: java.lang.NullPointerException
  | 	at org.jboss.seam.core.ManagedPersistenceContext.getEntityManager(ManagedPersistenceContext.java:96)
  | 

Thank you for taking a look at this,
