I'm using JBoss4.2.2 with EJB3 stateless session bean and JPA/Hibernate with Oracle10g:
I can query the DB w/o any problems. When I do update, I got
"javax.persistence.TransactionRequiredException: no transaction is in progress" on the
EJB client side. There is no Exception on server side.
Here is the update method in stateless session bean:
@TransactionAttribute (TransactionAttributeType.REQUIRED)
public void changeSalary(int id, long salary) throws IOException
{
Employee empEntity = this.entityManager.find(Employee.class, id);
empEntity.setSalary(salary);
this.entityManager.flush();
}
Here is the EJB client code:
...
Context jndiContext = getInitialContext();
Object ref = jndiContext.lookup("java:EmployeeServiceBean/remote");
employeeService = (EmployeeServiceRemote) PortableRemoteObject.narrow(ref, EmployeeServiceRemote.class);
employeeService.changeSalary(45, 2l);
...
Here is the jndi.properties file:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming
rg.jnp.interfaces
java.naming.provider.url=jnp://localhost:1099
