Well, you can use a web browser. Web browsers simply open a connection (via a
socket) and talk HTTP to a web server of some fashion. SOAP requests are the
same. The client opens a connection and posts data to the url of the
rpcrouter. The rpcrouter then uses the SOAP software to look up the appropriate
code on the server, in this case probably the hello.Server class. The
hello.Server class does some thinking and then sends this information back to
the SOAP client by way of the rpcrouter (the whole process in reverse).
So if your SOAP client is trying to connect to
http://<yourserver>/servlet/rpcrouter, then to see if that server is "up" you
could point a web browser to the same URL. Since SOAP requires that it receive
requests via HTTP POST, you'll get an error asking you to send a POST instead of
a GET (which is what browsers typically send to get a web page). This doesn't
matter, as long as you don't get a connection refused error. If you get a
connection refused error, then you weren't even able to make that initial
connection to the server. It looks like this is your problem.
Once you understand a little more about HTTP you can even use (or write) other
programs which will interactively send data to the web server. But for now,
just try to point a web browser to http://<yourserver>/servlet/rpcrouter and see
if you get anything back.
If the web browser works, and the SOAP client doesn't, make sure the SOAP client
is making a request to exactly the same URL as the browser. You may need to
look at the code for hello.Client. If you're connecting to
http://bob.com/servlet/rpcrouter then make sure that's what the SOAP client is
connecting to. You may be tempted to try and just connect to localhost or
127.0.0.1, this often does not have the same meaning to Apache or Tomcat as a
regular routable name/IP does, so don't assume that will work without checking.
So, first make sure your web server is running, then make sure both clients are
going to the same place.
