Need help on Apache SOAP

Question

Hello all!
Im trying to build a Light soap client, in short i will not use the soap.jar package. Just the plain old URLConnection.
My question is this... How will i be able to get the response of http://localhost:8080/soap/servlet/rpcrouter if that url doesn't allow GET "Sorry, I don't speak via HTTP GET- you have to use HTTP POST to talk to me."???
I got "java.io.IOException: Server returned HTTP response code: 500 for URL: http://localhost:8080/soap/servlet/rpcrouter" this error whenever I tried urlConn.getInputStream()
How does soap.jar GET the Response, and what URL is it using?
Any help is really appreciated...
Thanks is advance!!!
Here is my code:

import java.net.URLConnection;
import java.net.HttpURLConnection;

Probably what you need to do is use HttpURLConnection instead, and then use setRequestMethod() to set the HTTP request method to POST instead of GET... you've already got it imported, but it doesn't appear you're actually using it anywhere... So, instead of:
     private     URLConnection urlConn;     you'd:
private HttpURLConnection urlConn;
and then do this:
urlConn.setRequestMethod("POST")
in youre initialize() routine, before you call connect(), wherever that is (my eyes must be deceiving me at the moment, I don't see it anywhere... ???)
You shouldn't be using GET anyway for web service requests per the SOAP HTTP Binding specification...
