Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi,

I am new to GWT and I'm trying to install GWT desinger in my Eclipse 3.6.

When I am opening the design page, then I'm getting the enclosed error.

This error is occurring in GWT 2.5.1 

I have tried to search many forums but could not get answer.

Please let me know If I've done something incorrectly or missed to configure.

The error stack trace is:
