Subject: clarification regarding web services...Hi all,
I have a copule of doubts in Web services
1) Can a service enpoint in java be a EJB or a Java Bean apart from a servlet..
[Guy Katz] EJB endpoints are available (even though under the hood it probably is a servlet). java beans endpoints are not availavble (even though with a servlet endpoint the object that is being invoked can delegate to a java bean)2) In both asynchronous and synchronous service model, does the web container with which the client speaks to should (mandotorily) have a JAX-RPC Servlet enpoint mounted on a container..
[Guy Katz] you can use JAXMServlet to recieve SOAP messages3) In case of asynchronous service model, does this servlet needs to contact a JMS which in turn speaks with
a) the MDB hosted on a EJB container to DB (or)
[Guy Katz] if you use a servlet endpoint with JAX-RPC than you will probably use JMS. its not that the servlet NEEDS to contact JMS its something you do in your code
b) Connector which speaks with legacy systems
[Guy Katz] see a4) does all the application servers support both the above forms of message providers (i,e) JAXM and JAX-RPC.
[Guy Katz] no, they are mandated to support only JAX-RPC (and only since J2EE 1.4) but you might find many supporting JAXM also.5) Does the UDDI registry always has list that supports JAX-RPC whom could be searched using a JAXR.
[Guy Katz] did not understand the question. JAXR is the API to search UDDI registries. i dont know what is th elist you talk about. but its been a while since i eplyed a web service.
Can someone thro light on the above in detail please..
