Hi guys,
Just to put you in the picture, I've integrated Axis into our
transaction server. So it can receive SOAP messages on a TCP/IP socket
and invoke a public method on the server, and return a response SOAP
message.
Here's the problem
When I invoke a method that calls a method on another object, I get a
NullPointerException (see below).
When I invoke a method that doesn't call any other objects, and just
returns a response object, it works fine.
I need to be able to call methods on other objects, since our business
logic is in another Java Class.
Any ideas how I can fix this?
