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:
--------------------------
