Bob,
From your description of your 2.1 installation:
eclipse 2.1 platform runtime binary + jdt installed
it makes me wonder if you installed the complete and unabridged version of Eclipse 2.1 or did you just install only the pieces you’ve listed? We only test on the complete Eclipse 2.1 product drop, not on any of the “lighter” configurations.
MyEclipse Core/Server show up in Customize Perspective/Other dialog
That’s odd that you list only those two because MyEclipse-WebTooling should be there also. I’m going to guess that for some reason that component couldn’t be initialized in your Eclipse 2.1 installation. The reason that this occured should be displayed as a stacktrace in you log file located at <eclipse-workbench>/.metadata/.log
Would you please check there and see if it reveals any dependencies of the web tooling component that aren’t being satisfied?
