title: get 502 bad gateway error when calling a webservice
body: <p>In my SEAM web application running under JBOSS-AS 4.2.3 there is a plain SOAP message call to a webservice, using SOAPConnection.call().
  The call ends up with a
  org.jboss.remoting.CannotConnectException: <strong>Can not connect http client invoker. Invalid HTTP server response [502] - Bad Gateway</strong>.</p>
  
  <p>Running the same code outside the JBOSS as a pure java application all works fine.</p>
  
  <p>So question: Is there something in JBoss I have to configure that makes things work ?</p>
  
  <p>Thx for answers,
  Frank</p>
