Atomikos Forum

I'm developing on Spring 3.0 + Hibernate 3.3 + MySQL 5.1. Everything works fine with HiberateTransactionManager. Now I add Atomikos 3.6.2 to support XA, but fails to complete transactions and have the following warning message:

My Spring context is

<bean id="AtomikosTransactionManager" class="com.atomikos.icatch.jta.UserTransactionManager" init-method="init" destroy-method="close">
    <property name="forceShutdown" value="false" />
</bean>

Anyone knows the reason?
