I'm trying to install a jQuery plug in for eclipse from http://marketplace.eclipse.org/content/jquerywtp it comes as a .jar file. I've tried going to help0---> install new software and adding the jar from the "local" and "archive" options it has there but it causes errors and doesn't allow it. I've been reading online that you are supposed to place these files inside of the plugin or dropins folder inside of eclipse directory. So I've placed both the .jar files and the extracted folder inside of each but I still cannot see that the software was installed correctly. I've checked the help--> about eclipse--> installed software list and it is not showing up there. How can I install this plug in?
