[jboss-user] [Installation, Configuration & Deployment] - 4.0.1sp1 upgrade to 4.2.0GA with webapp using Hibernate 3.0.

I have a webapp that I've been running on JBoss 4.0.1sp1 (and prior versions) for a couple of years - the war is self contained and is using Hibernate 3.0.5. Deploying this same webapp to 4.2.0GA I get exceptions when the SessionFactory tries to initialize: | 2007-05-29 23:46:53,203 ERROR [STDERR] java.lang.ClassCastException: com.arjuna.ats.jbossatx.jta.TransactionManagerDelegate | 2007-05-29 23:46:53,204 ERROR [STDERR] at org.hibernate.transaction.JNDITransactionManagerLookup.getTransactionManager(JNDITransactionManagerLookup.java:23) | 2007-05-29 23:46:53,204 ERROR [STDERR] at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:270) | 2007-05-29 23:46:53,204 ERROR [STDERR] at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1005) | The lines in my hibernate.cfg.xml file related to the Transaction Manager look like this: | <property name="connection.datasource">java:/datasourcename</property> | <property name="show_sql">true</property> | <property name="dialect">org.hibernate.dialect.MySQLInnoDBDialect</property> | <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property> | <property name="hibernate.transaction.manager_lookup_class"> | org.hibernate.transaction.JBossTransactionManagerLookup</property> | And my datasource configuration looks like this: | <datasources> | <local-tx-datasource> | <jndi-name>datasourcename</jndi-name> | <connection-url>jdbc:mysql://localhost/databasename</connection-url> | <driver-class>com.mysql.jdbc.Driver</driver-class> | <user-name>user</user-name> | <password>password</password> | </local-tx-datasource> | | </datasources> | | I gather the Transaction Manager in 4.2 is now different. Do I have to configure something different, either in my datasource or my hibernate config? Thanks, Kevin View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4049602#...
