this is what i was wondering. i've done EAI. i understand SOA fine.
i just don't know how to connect a web application to this. most
enterprise
code i've done was written around an existing enterprise application in
the
first place. and most of that was in JMS.

i see spring supports "services". that sounds like a good integration
point,
since it will probably be transactional. just wondering what to do if
they chose
struts, or something else. my thought right now is to use the service
support in
spring. if they go struts, create a session facade and expose a SSB
(EJB) as a web service.

Could you be a bit more clear on what you are asking about and also what
the architecture of the existing system is. That would make it a lot
easier to help you.

for example, you mention jms, is that the interface of the existing
systems? you also mention spring "services" are you talking about spring
support for web services/soap, jms or web app. And kind of client are
you looking to connect, a web app?
