If there is something clever you can do in Axis2, then I don't know it. (Can somebody else reply?) The only way I know is the straightforward approach; in your 1st web service impl method, simply get a stub to the 2nd service and call into that. Here, the impl method is acting as a dumb client of the 2nd service. Of course, the performance of chaining web service calls will be at a minimum, the addition of the time taken for both calls. I don't know the EPR question, either. If you find out how to do this, can you post the solution on this mailing list for all to see and learn? Thanks, -jeff _____

Date: Wed, 15 Aug 2007 11:57:53 -0400 I'm confused now, not sure what you mean "..use WSDL to connect two web services" ? In Axis, you run the WSDL file through the WSDL2Java class. If you get all of the arcane arguments right, that will produce a set of classes, which will include the stub you use on the client side, and the skeleton you use on the service side. (I use Axis1.3, but most people have moved to Axis2). In .NET it's the same thing, run the WSDL file through the wsdl.exe program (again, more arcane arguments to the exe, but Microsoft has a decent explanation of the argments to wsdl.exe on their website soemwhere). This produces the classes you need in C# (or whatever language you specified), just like in the Java counterpart example. If you download the Axis2 binary zip file, there are a dozen or more examples of using web services to do many things. Can you be more speciifc in what you're looking for? For a web service to use another web service, it has to act as a client. Then the 2nd web serivce acts as a client of the 1st service. The "two web services" question has me confused. -jeff _____ From: shams jawaid [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 15, 2007 11:42 AM To: axis-user@ws.apache.org Subject: RE: Is it possible to access external services?
