Hello all,

I have got the below question.

When invoking a web service in J2EE, in any of the ways mentioned below :

  • SAAJ API - SOAPConnection.invoke
  • Dispatcher Interfaces
  • SEI - Generated by tools such as wsimport

  • My question is, can I make many web service invocations utilizing the same socket connection, without having to open and close a Socket a connection every time I invoke a web service. If I am to call the web service directly using the standard socket APIs, I would add a header which is
    [Connection: Keep-Alive] so to keep the connection opened and to be used later on.

    This is applicable in the various web service APIs mentioned in the list below that are available in the J2EE.

    Many thanks in advance.
