This is exactly the idea.

That message looked too familiar, so I looked at the response on my server 
when I used a partial HTTP Request, ie 
http://servername:8080/sanjose/services. 

The response was a page that provided that exact message, along with a list of 
services and links to individual WSDLs.

I was firmly under the impression that web services MUST ( as in RFC2119 ) 
understand the SOAP HTTP GET without any further wrapping. I may have gotten 
this wrong ( Serendipitously ).

This link http://www.w3.org/TR/soap12-part0/#L26854 might come in handy 
though.

The web service was generated with all default parameters and a look at the 
wsdd gives the following for the method that I was talking about :

<service name="Repair" provider="java:RPC">

ps : I found the Axis TCP Monitor ( org.apache.axis.utils.tcpmon ) MOST 
helpful during the initial development phase. 

pps: would you consider running axis within Websphere, to have this 
functionality ? :)
