Defining HandleDelegate Service Provider Interface
 Technote (troubleshooting)
 
Problem(Abstract)
What is the HandleDelegate SPI?
 
Resolving the problem
The javax.ejb.spi.HandleDelegate service provider interface defines methods that enable portable implementations of Handle and HomeHandle that are instantiated in a different vendor’s container to serialize and de-serialize EJBObject and EJBHome references. The HandleDelegate interface is not used by enterprise beans or J2EE application components directly. EJB, web and application client containers provide implementations of the HandleDelegate interface.
The HandleDelegate object is accessible in the client J2EE component’s JNDI namespace at the reserved name “java:comp/HandleDelegate”.
Portable implementations of Handle and HomeHandle must look up the HandleDelegate object of the container in which they are instantiated using JNDI at the name “java:comp/HandleDelegate” and use the HandleDelegate object to serialize and de-serialize EJBObject and EJBHome references.
