Subject Re: Server-Side as a Client of other Web Service
Date Mon, 02 Feb 2004 17:27:57 GMT
Scott:

It worked ok. Thanks a lot.
I use Tomcat and I would like to ask you another thing.

My Service dinamically invokes some other Services (as I told you :-) ),
so I get the URL of each of the Services dinamically (from my Database)
that I am going to call and send them some information.
The question is:

I want to test my application and, Is it possible tu run in the same
machine 2 Tomcats ?
If it is possible I could invoke each of those services just changing the
URL.
For example: I invoked the Listener over SOAP but this service is using
the same URL as my Service:
                    http://localhost:8080/soap/servlet/rpcrouter

Can I deploy another instance of Tomcat at the same time using a
different port number ? 
for example:  http://localhost:8010/soap/servlet/rpcrouter

Where Should I do ? Where Do I set the port number up ?

Thank you very much !!!

Max
