Re: Problem in viewing ui.xml in designer mode.

You have a JDK version mismatch between the JDK you are using to run 
Eclipse and the one you are using to compile your code. Make sure you are 
running Eclipse with the latest JDK.

Problem in viewing ui.xml in designer mode.

2011-11-18 Thread Neorj 
Hi,
I am new to GWT and uiBinder concept.
While trying out examples on eclipse Galileo. I stumbled upon the
following error below.
I started my eclipse using jdk1.6.0.
I am using Mac OS X Ver 10.5.8.
Any assistance would be of great help.

Regards
RJ
