[jboss-user] [JBoss Seam] - Re: Trouble Using <s:convertEntity/> on Glassfish

[soluble]

My persistence layer uses Hibernate as the provider and is the exact one from the Glassfish example that comes with the jboss-seam-1.2.1.GA download:

<?xml version="1.0" encoding="UTF-8"?>
  | <persistence 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" 
  |              version="1.0">
  |    <persistence-unit name="bookingDatabase">
  |       <provider>org.hibernate.ejb.HibernatePersistence</provider>
  |       <jta-data-source>jdbc/__default</jta-data-source>
  |       <properties>
  |         
  |          <property name="hibernate.dialect" 
  |               value="org.hibernate.dialect.DerbyDialect"/>
  |          <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
  |          <property name="hibernate.show_sql" value="true"/>
  |          <property name="hibernate.transaction.flush_before_completion" value="true"/>
  |          
  |          <property name="hibernate.cache.provider_class" 
  |               value="org.hibernate.cache.HashtableCacheProvider"/>
  |       </properties>
  |    </persistence-unit>
  | </persistence>
  | 

In fact the only difference my app has to the glassfish example is that I have added a few more session beans and facelets.

I should also mention that a few more stack traces also come up such as:

 Parent -> EJBClassLoader : 
  | urlSet = []
  | doneCalled = false 
  |  Parent -> java.net.URLClassLoader at ce16ad
  |  was requested to find class org.hibernate.event.EventListenersBeanInfo after done was invoked from the following stack trace
  | java.lang.Throwable
  |         at com.sun.enterprise.loader.EJBClassLoader.findClassData(EJBClassLoader.java:707)
  |         at com.sun.enterprise.loader.EJBClassLoader.findClass(EJBClassLoader.java:627)
  | ...
  | 

and


  |  Parent -> EJBClassLoader : 
  | urlSet = []
  | doneCalled = false 
  |  Parent -> java.net.URLClassLoader at ce16ad
  |  was requested to find class org.hibernate.util.CloneableBeanInfo after done was invoked from the following stack trace
  | java.lang.Throwable
  |         at com.sun.enterprise.loader.EJBClassLoader.findClassData(EJBClassLoader.java:707)
  |         at com.sun.enterprise.loader.EJBClassLoader.findClass(EJBClassLoader.java:627)
  | ...
  | 

and


  | javax.persistence.PersistenceException: org.hibernate.HibernateException: Could not instantiate dialect class
  |         at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:720)
  | ...
  | Caused by: java.lang.ClassCastException: org.hibernate.dialect.DerbyDialect cannot be cast to org.hibernate.dialect.Dialect
  |         at org.hibernate.dialect.DialectFactory.buildDialect(DialectFactory.java:78)
  | ...
  | 

I hope this helps.
