Class AbstractStatelessSessionBean

public abstract class AbstractStatelessSessionBean
extends java.lang.Object
You generally should not need to use EJBs in platform applications; this is provided primarily for backward compatibility. To control transactions from REST resources, see BaseResource. From server-side code, see TransactionSupport.

Base class for stateless session beans. Modules may define stateless session beans in order to leverage container-managed database transactions.

Platform uses EJB2 Stateless Session Beans for transaction management. You can add new stateless session beans to your Module by using the following conventions:

  • Name the class using the convention *Bean, for example RegistrationBean
  • Place the bean in the server package of your module (or a subpackage), for example com.mycompany.mymodule.server.RegistrationBean
  • Add XDoclet tags to define bean attributes such as transaction policy/etc. Each new Module is created with a SampleAccessorBean which you can use as a reference.
Deployment descriptors and Local/Home/etc interfaces are all generated by XDoclet. Source is generated into the build/gen-src directory of your module. If you navigate to that directory, you will see five classes generated for a class such as SampleAccessorBean:
  • SampleAccessor - Remote interface
  • SampleAccessorHome - Remote Home interface
  • SampleAccessorLocal - Local interface
  • SampleAccessorLocalHome - Local Home interface
  • SampleAccessorUtil - Utility class for acquiring Remote and Local Home
In Platform it is not necessary to use Remote interfaces. EJBs are always hosted in the same VM as their clients (including the web layer), therefore you should write all your code to the Local and LocalHome interfaces.
