I\'m trying to debug this problem but not sure where exactly i need to replace SWT jar file for Eclipse.
Current System Config:
Ecl
I also faced the same problem a long time ago.
Here is the Solution
In Eclipse Click on "Windows"-->"Preferences"---->"Java"---> "Installed JREs"---->Select the JDK, click on "Edit".
Check your JDK path, is it according to your path in environmental variables defined in system. if not then change it to "path" defined directory.
