Subject can a web service find out its own url?
Date Thu, 18 Jul 2002 23:31:31 GMT
Is there any way for a web service to discover, build, or calculate the 
url that was used to call it?

In my system, I need to have one web service send its url and an 
operation name to another web service. Is there enough information 
available to a web service, during an invocation of one of its 
operations, to let the service figure out how it was called?

Another possibility would be to have that string in a system property 
somehow. Is there one of the Axis  or Tomcat config files that would let 
me set system properties that would be available to a web service?

I've also considered putting this information in a property file, but I 
haven't been able to find a place to put the file that is on the class 
path of the running web service, even though I've tried it in every 
directory under the Axis root. Also, the property file idea just moves 
the "what url?" question from run-time to deployment time.

Hopefully this looks more complicated to me than it really is, and 
someone can think of a way to manage this. Or another idea for how to 
arrange one web service to tell another one how to call back.
