Title: clarification regarding web services...

Hi, For your queries, I suggest you chcek the vendor docs to find out how they are supporting webservices. You can use stateless session bean in J2EE1.4, which is specified using the <service-impl-bean> tag in the webservices.xml. You should check you server vendor document for the support on the exact support on this. Once your call is in EJB or a servicve endpoint class, you can use API for messaging like noemal EJB/J2EE programming. It is important to note that in J2EE1.4 web services, the JAX-RPC servlet that accepts webservices call is provided by the JAX-RPC runtime system (and not by the developer). A developer provides the implemenntion of service endpoint, using a stateless session bean or a service endpoint class. The user developed classes are then associated with the JAX-RPC servlet. -Hemant www.pramati.com ----- Original Message ----- From: Kesavanarayanan, Ramesh (Cognizant) To: [EMAIL PROTECTED] Sent: Tuesday, May 04, 2004 4:09 PM 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.. 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.. 3) 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)         b) Connector which speaks with legacy systems 4) does all the application servers support both the above forms of message providers (i,e) JAXM and JAX-RPC. 5) Does the UDDI registry always has list that supports JAX-RPC whom could be searched using a  JAXR. Can someone thro light on the above in detail please.. Regards Ramesh Kesavanarayanan [EMAIL PROTECTED] Cognizant Technology Solutions India Pvt Ltd.
