I am getting Cannot enlist Synchronization. LocalTransactionCoordinator is completing or completed exception when integrating my method is called from the portlet.

I am using spring transaction management for handling all the hibernate transaction in the spring configuration file through AOP.

When I run my hibernate dao method for persisting the data through Junit its working fine.

Exception description:

I am facing an issue that is when I run my code through unit test case data is getting updated in database properly but when I run the same code with integration with portlet my code is executing finely but after the completion of transaction the records is not getting updated to database. The following error can be seen in the log which is
