Applications based on Enterprise JavaBeans (EJBs) can benefit in many ways from using the Object Management Group (OMG) Notification Service. However, there are challenges to operating the Notification Service in an EJB environment. To highlight some of the more significant challenges and benefits, two cases are presented here. The first involves a distributed EJB-based application that uses the Typed-Event Notification Channel to improve its throughput, reliability, and scalability. Here, the challenge faced is propagating ValueTypes through the Notification Channel. The second case involves subscribing EJB to the Structured-Event Notification Channel as one approach to integrating the Java 2 Platform, Enterprise Edition (J2EE) and the CORBA platform for event-based applications. In this case, the challenge faced is the requirement to “RMI-ize” structured events.
