If i understand you correctly: On 80 a web server (like apache,tomcat) 
is running.
You can't use our XmlRpc for this as in this case the XMLRPC server must 
be xmlBlaster itself (running on port 80 or 8080 ...).

If you want to use a servlet approach there are currently only two 
options a.f.a.i.k:

1) Using an applet
   xmlBlaster/src/java/org/xmlBlaster/protocol/http/appletproxy/README 
(servlet setup)
   
xmlBlaster/src/java/org/xmlBlaster/client/protocol/http/applet/README 
(applet setup)
   xmlBlaster/demo/http/applet (applet example)

2) Using a javascript client in a browser 
(xmlBlaster/src/java/org/xmlBlaster/protocol/http/ajax/AjaxServlet.java)
 Here you have the complete Ajax based xmlBlaster access.

In case you need a stand-alone java client with bi-directional 
communication you
need to code some lines yourself, probably the applet code is a good 
point to start.

About you questions below:
This works fine here:
 java -Dcom.sun.management.jmxremote org.xmlBlaster.Main
 java HelloWorld3 -protocol XMLRPC
your configuration looks ok but i think the server names are somehow 
invalid,
