1)
Both in JDK 1.3.1_01 and 1.4.0-beta2,
calling getInputStream on a URLConnection for which the server returns a staus
code of 500, result in a IOException like :
java.io.IOException: Server returned HTTP response code: 500 for URL:
http://easysoap.sourceforge.net/cgi-bin/interopserver
This makes impossible using HttpURLConnection for reading SOAP responses, like
example 9 of the SOAP 1.1. spec.
