RE: servlet

[John Twomey]

Hi Louis,
 
Using a standard HTTP POST does not seem to work since the post method
will URLencode(or something - its early) the XML-RPC call. The Post
includes headers etc. and some charactors are encoded - XML RPC only
wants the call as you have it in your post box. This can be confirmed by
the fact that you recieved an answer from your "LiteClient" - so your
servlet works!!!
The answer probably lies in using the XML-RPC applet to make the call
and probably process the return.
 
Thats My take on it anyway - others may have more to add or take away. 
If someone has an answer to making an HTTP POST work I would love to
know it. 
 
 
Take care,
 
John

        I know the server is running as I started it like so
        
        C:\>java org.apache.xmlrpc.WebServer 9000
        And this works
        C:\tom4\webapps\examples\WEB-INF\classes\org\apache\xmlrpc>
        c:\java14\bin\java org.apache.xmlrpc.XmlRpcClientLite
        http://lou.library.arizona.edu:9000 echo test 123
                [test, 123]
