Thanks... We want SOAP server to do the work asynchronously after client sends login XML. Along with JSESSIONID/Cookie, we send application level 20 char unique handle to client as login's response. Client sends its XML with JsessionID (Session Scope)+ application hanldle(20 char) on every transaction. We want to use a pool of sockets (worker bees) and hand over transaction XML to one of the sockets in the pool. We do not know when we will get answer back from down stream server. (Usually we get answer back in 400ms). The question is after we get answer back, how do we jump back to tomcat5 thread (that is providing class of SOAP Service) to send response back to correct real world SOAP Client using return(XML..) statement?
Are you saying in "Callback" solution that after we have session established on Server, we create a dummy client call to SOAP server itself and wait for Server to call back after answer is ready? and once dummy client gets answer, call return(XML) method so that real client in Internet world would get its answer? May be I will have to study more about end-point Information...

It is, of course, possible to implement something on your own. There are at least two varations: 1. Initial request and polling. The client makes the initial request and the service returns a token that uniquely identifies the request. The client then periodically calls another method, pass the token as a parameter, to see whether the work is done. If it is, the service returns the result of the work. 2. Callback. The "client" is also a SOAP server. It makes the initial request to the server and includes in its parameters the SOAP endpoint information for the callback from the server. When the server finishes its work, it uses the endpoint information to send the result to the "client".

Today we use return(XML response) in the same SOAP session so no issue there. Is there any variation of return call in SOAP environment that can pass JSESSION id so that proper client gets the response back on same https session with Apache? Thanks. Vivek
