Hi all, I'm getting a very strange problem with Jboss 4.2.2GA and Spring 2.5.3. I have the following in my spring context. | <tx:jta-transaction-manager /> | Using this setup (same implementation class, JTATransactionManager, different tag) is recommended here. http://wiki.jboss.org/wiki/JBossTransactionsWithSpring However, I'm getting this exception. org.springframework.jndi.TypeMismatchNamingException: Object of type [class com.arjuna.ats.jbossatx.jta.TransactionManagerDelegate] available at JNDI location [java:/TransactionManager] is not assignable to [javax.transaction.TransactionManager] According to this jboss doc, the JNDI location java:/TransactionManager should be an instance of javax.transaction.TransactionManager. Any ideas why I'm getting this exception? This transactionmanager integration worked perfectly on 4.0.5 http://docs.jboss.org/jbossas/jboss4guide/r5/html/ch4.chapt.html#d0e9950 Thanks, Todd View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4145035#...
