So I did some searching and found this post, which says to add the Glassfish plugin the normal way from http://ajax.dev.java.net/eclipse. For those unaware on how to do that, these are the steps:
- In Eclipse 3.5, click Help menu, then Install new software...
- Click the Add... button.
- Paste http://ajax.dev.java.net/eclipse in the location text box, then click OK.
- When the search is complete, the Glassfish JEE5/JEE6 adapter will show up first in the list. Click the checkbox, the click Next.
- Click Next again, then Finish, and restart Eclipse when the adapter is installed.
