Subject trouble with "Building Web Services" ch3 ex2: please help!
Date Thu, 31 Jan 2002 02:03:49 GMT
Hi,

I'm having trouble running Chapter 3 Example 2 from the otherwise
very good book "Building Web Services with Java", and since I'm
new at this it's hard to figure out where the problem is.  I've setup
Tomcat 3.2.4 and the examples according to the book's example
installation instructions.  Up to that point, all examples work properly.
However, when I press the "Check inventory" button on that example,
I get a java.lang.Exception: Null response message!,
the first part of which is reproduced further on below.

It's true that during example deployment, I got this rather strange
message from Axis, which I don't know whether it's an indication
of a real problem or not (and if so, what is it?):

Axis status messages:
Processing file: 
C:\Tomcat\jakarta-tomcat-3.2.4\webapps\bws\resources\deploy.xml
Null response message!
Doing a list
Null response message!

Axis deployment response:
null
Axis deployment listing:
null

Please help.  I think this book will be very useful to me for learning
about Web Services, but if this basic example doesn't run, I'm stymied.
I followed the instructions precisely, and therefore had the expectation
that the examples would work correctly, out of the box!
Oh yeah, I'm using JDK 1.3.1_02.  Many thanks!  -- Ivan
