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

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@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@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.
