Subject Calling calculator sample from VB in Visual Studio 2005 not working
Date Wed, 15 Feb 2006 14:51:28 GMT

Details
Axis: 1.5 built from source
Platform: Red Hat Enterprise Linux AS release 3 (Taroon Update 5) Kernel
2.4.21-32.EL on an i686
Compiler: gcc 3.2.3 20030502
Web server: Apache 2052

I configured apache as directed in the documentation and have been able
to run samples on the Linux server from the command line. From Visual
Studio, I am able to create a web reference by entering the url of the
wsdl file for the calculator sample. I placed this wsdl file in the
document_root directory. Visual Studio correctly discovers the web
service api and allows me to create a web reference that I can then use
in the VB code. When I try to make a call to the web service, however,
the call fails with the error code 405. I used ethereal to trace traffic
from the client machine to the web server and observed that no message
was sent. I am a complete XML and wsdl novice. I looked at the wsdl and
noticed numerous instances of the string 'localhost'. I replaced these
with the host name of the Linux server. This changed the error but still
there was no traffic to the Linux server. I previously had installed the
Axis Java toolkit (1.3) and was able to create the web service reference
and successfully make the call to the GetQuote service. I'm not sure
what I need to do here. Do I need to modify the wsdl for the calculator
sample to get it to work?

In the end, of course, I need to create a web service to accomplish the
goals of my current project. We will use the created web service to
replace an existing interprocess communication library that is not
thread-safe. I understand that the code generation tool, WSDL2Ws, will
generate C++ stubs from wsdl, so it seems that my initial task will be
to create the proper wsdl for the service I am creating. Thus, I need to
learn enough XML and wsdl to accomplish this task. Is this correct?
