Installed SpringSource dm Server Tools (required) version 188.8.131.52008251000-M3
At least EclipseRT now shows up in New->Server->Server
EDIT: Also had to modify Run->Debug Configurations for Virgo Web Server at localhost and add the following to VM arguments to avoid PermGen errors:
-Xms512m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=512m
Hmmm. Did you try following the exact steps in the Virgo programmer guide? I think you gave the impression earlier that you were carefully following these steps, but it's easy to make assumptions.
Also something may have regressed in the latest version of STS for all I know. We can only test with certain versions of STS and we certainly can't keep up with every release.
If you're confident you are following the programmer guide pretty closely, please raise a bug against Virgo describing exactly what steps to take to reproduce the problem and we'll look into it. (If we get into genuine tooling issues, we will need to involve our tooling experts, but let's not presume that will be necessary for now.)
