If you are trying to run and test the Http-bing example, and get an error like this
Exception in thread "main" java.io.IOException:
Server returned HTTP response code: 500 for URL: http:
Then it means that you don't have JDK 5 installed.
Fix
This problem is due to the Sun SAAJ implementation we use which is only compatible with JDK 5.
Please update your J2SE Development Kit to JDK 5 to run it without any problems. You can download JDK 5 at http://java.sun.com/j2se/1.5.0/download.jsp
