Currently Being Moderated
Am using Eclipse 3.3.2

I have a project called: SWDS
Initially i have JDK1.6 installed in my system. At this time the project is running succesfully.

But when i removed(uninstalled and environment path also removed) JDK 1.6 and installed JDK 1.5 and path also given.

No changes are made in the project code.
When I Run the project SWDS then showing an alert "*Could not find the main class. Program will exit*" and then getting error messages like:
