Re: Server-Side as a Client of other Web Service
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 !!!

Re: Server-Side as a Client of other Web Service
Posted by Maximiliano Barone <mb...@tourch.com.ar>.
Scott:
In this case, I want to change the URL of each of the Listener's
Services, so I have one Listener (Listener.class) in my
TOMCAT_HOME/shared/classes path (in the same Tomcat instance of my
service).
All of my listeners are going to use the same class and class' name.
How could I use another Listener (Listener.class) ? Where do I have to
put this class ?
If I call the Listener.class from my Service (Caller) , which of both
Listeners are going to receive it ?
Thank you very much.
Max.
