I have Eclipse EE Indigo installed, when I first checked “new server wizard” I saw such servers as JBoss, Tomcat. However since I am interested in Jetty or Glassfish I installed extra adapters for those (via “download additional server adapters” in Eclipse).
I restarted Eclipse and the list didn’t change — still JBoss, Tomcat and other old stuff. On the other hand I don’t see Jetty and GF in “download additional…” window.
As desperate try I installed Jetty WTP, restart, no change.
How to make newly installed adapters visible? After all I would like to use those servers (Jetty or GF).
May be you can try installing them as a new software install: http://wiki.eclipse.org/Jetty_WTP_Plugin/Jetty_WTP_Install
I installed jetty adapter like this and it is visible in eclipse servers now.
