This is rajib a ruby nub...e .

I was looking for some serious gui programming on GUI in ruby when i
came upon the Rubywebdialog .. a wonderful approach for universal GUI.

I rushed througn the instruction etc in
http://www.erikveen.dds.nl/rubywebdialogs/index.html..

And tried to run rwdhelloworld.rbw. But some strange error is appearing
  .... can any one point me to my mistakes
