i using windows 7 64 bit. tried jdk 1.7 (both 32 , 64 bit, changing winodws ->preferences) no luck.

ms office version 2007.

finally, got work.

  1. one need jdk 32 bit. point eclipse jdk 32 bit windows->preferences
  2. even after step 1, system library still points 64 bit. remove , change 32 bit manually under java build path->libraries. above lines, work.
