[jboss-user] [JBoss/Spring Integration] - no transaction is in progress exception

[springfans]

I'm using Spring 2.5, Hibernate, JPA and WLS9.2, and I'm having some problems using the @Service annotation. I have a service implementation class annotated with @Service, the service class has a method called saveUser. Inside the saveUser method I do jpaTemplate.persists and jpaTemplate.flush . When flush is called, "InvalidDataAccessApiUsageException: no transaction is in progress" gets thrown.

Here's the stack trace:
