[news.eclipse.tools] Getting Runtime error in running javaeditor example

[sma_r@xxxxxxxxxxx (Syed)]

Hi all,
I am trying to run the javaeditor example but I get a runitme exception
while I open up a file with .java extension,I get this error; Unhandled
exception caught in event loop Reason:java.lang.ExceptionInitializerError.
But when I open up a file with a.jav extension I get a error dialog
stating this: "Unable to create part:hello.jav" and in the editor area I
get a message in red that"An error has occured when creating this editor.
any idea how to fix this problem. 

I will apprecaite your help

Syed
