I recently downloaded the JEE+BIRT package of Eclipse 3.6 (Helios) for 32-bit Windows (Windows Vista, I know...) to give it a whirl. I am using this alongside the J2EE package of the JDK Sun provides, which of course includes GlassFish v3. This is a clean installation with the old .eclipse configuration directory and Eclipse workspace folder blown away.
It looks like the GlassFish Adapter was available via the Eclipse Marketplace, so I tried that. It mentioned something about unsigned content (appearing to have eclipse-3.5 in the file names), but I OK'd through that. On restart, the Installed Software panel shows the GlassFish Adapter to have been installed, but I cannot find GlassFish among the server runtime environments to add.
So I blew away everything again and tried installing the adapter per instructions found on this blog. I added the repository from the URL specified (http://download.java.net/glassfish/eclipse/helios), unchecked the group by category option, and chose to install the adapter. Again, I got a warning about unsigned content but OK'd through it. On restart, again it shows the adapter as installed, but again I cannot find it as one of the server runtimes to use.
Anyone had any luck with this?
