eclipse error in hibernate struts project

Question

when i tried to run a program it popped a window titled as " Problem Occured" specifying that Could not delete D/wrkspace/ metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/MyProjectAdmin/WEB-INF/ classes/AdminLoginPackage. May be locked by another process

Answer 1

The WEB-INF/classes folder generally contains the compiled class files. You have something that is running and/or is viewing the files. Check for file browsers, running instances, etc, try rebooting the machine and deleting the files manually. That is what the lock is reporting.
