Subject Problems getting simple RPC to work - exceptions preparing the call
Date Thu, 11 Nov 2004 19:31:11 GMT
I'm trying to use a vendor supplied WSDL file to generate a mock server
to help test our client code [pending the vendor completing their
server]

Is there a _simple_ step by step guide for setting up an Axis based
client and server, based on WSDL? [one updated for recent versions of
both Axis and Java??]

Development environment Ant [command prompt] or Eclipse 3.0, WinXP, JDK
1.5, Tomcat 5.0.28, Axis 1.2RC1

Target environment [SunOS 5.8, JDK 1.3_07 [with jsse], ATG Dynamo]

I was able to integrate a test environment with Dynamo, that would act
as a SOAP client. On my local workstation, I cannot get a simple client
& server to communicate - the Client exceptions out before calling the
server.

I can post source code, the WSDL file & my ant build script.

I've noticed that the stack trace dumped at the console does not
resemble the state reported by the debugger - not certain who to
believe. [have to see how to coerce program state information out of
Eclipse]

It may work in practice, but does it work in theory?
