22.3. Review

There are many pieces involved in the construction of an EJB. Besides writing the session bean implementation, there are the remote and home interfaces to be written. The local and local home interfaces are optional, but useful, especially in cases where arguments cannot be serialized or where you know that the beans and the client will reside on the same host. Compiling an EJB is not different from any other Java compile, but it requires a special JAR in your classpath, one that contains the definitions of the J2EE objects and interfaces.
