With Spring 3.5.1, I want to write a Service Facade class and a Service Entity class to query a database table that come with Liferay 5.2.8 (EE SP4). But there is some problem when the framework try to hook up with the entity bean. When I deploy the WAR file to liferay hot deploy directory, it thrown the following exception:

Caused by: org.springframework.dao.EmptyResultDataAccessException: No entity found for query
at org.springframework.orm.jpa.EntityManagerFactoryUtils.convertJpaAccessExceptionIfPossible(EntityManagerFactoryUtils.java:295)

Here is the ServiceFacade.java file:

The Service.java file:

Any suggestion is much appreciated.

It is sorta covered in the JavaRanch Style Guide.
