Interoperability
Although it’s nice that the dependency injection facilities allow components within EJB to play nicely, we don’t live in a bubble. Our application may want to consume data from or provide services to other programs, perhaps written in different implementation languages. There are a variety of open standards that address this inter-process communication, and EJB leverages these.
Interoperability is a vital part of EJB. The specification includes the required support for Java RMI-IIOP for remote method invocation and provides for transaction, naming, and security interoperability. EJB also requires support for JAX-WS, JAX-RPC, Web Services for Java EE, and Web Services Metadata for the Java Platform specifications (EJB 3.1 Specification, 2.6).
