It seems that the major problem that EJB currently have (and would hopefully
be solved by the EJB-JMS integration) is EJB primarily focuses on POP-style
applications. That is when the server starts nothing really happens. It
takes a client to submit a request to get things going. Then the AS cranks
up it's service, activates the objects, sends requests here and there. Ie.
the information is _pulled_ out from the ejb-application. EJB simply
fulfills a clients requests. This is pretty okay because the webb is pretty
much a POP-oriented world as well.
But mysterious things are happening to the web. Strangely encoded CORBA/DCOM
method-calls, straying and confused EDI-messages and blistering,
hyper-modern b2b xml-documents is beginning to find it's way around the web,
mainly using the http post-method.
The web is starting to become more and more MOM-oriented. It's okay, http
1.1 is a better protocol than one would think. Also, the EJB-design has to
meet these new requirements of web-applications. The b2c electronic-commerce
applications are mainly POP-oriented, there's not really a system receiving
messages. B2B has another requirements.
For EJB to succeed it really needs great support for JMS.
