The Handle is less stable than the primary (Web hosting java)
The Handle is less stable than the primary key because it relies on the networking configuration and naming the IP address of the EJB server and the JNDI name of the bean s home to remain stable. If the EJB server s network address changes or the name used to identify the home changes, the handle becomes useless. In addition, some vendors choose to implement a security mechanism in the handle that prevents its use outside the scope of the client application that originally requested it. How this mechanism would work is unclear, but the security limitation it implies should be considered before attempting to use a handle outside the client s scope.
