(I first wrote this in eclipse.platform a few days ago, but I got no
response.)
I'm using SDK 3.3.1. I've been using it for a few weeks, and I managed to
update a bunch of plugins when I first set it up, using the Update
Manager. Today, I thought to check to see if there was a new version of a
particular plugin, and when I tried to bring up the Update Manager,
nothing happened. I checked the console, and saw this:
java.lang.NoClassDefFoundError: org/eclipse/update/ui/UpdateManagerUI
at
org.eclipse.ui.internal.ide.update.ConfigurationManagerActio n$1.run(C
onfigurationManagerAction.java:43)
at
org.eclipse.swt.custom.BusyIndicator.showWhile(BusyIndicator .java:67)
How the heck could I have lost my Update Manager classes?
I searched for this class in my plugins, and I found it in
"org.eclipse.update.ui_3.2.100.v20070615.jar". Why isn't Eclipse finding
this?
Note that I also have a separate installation of RAD 6, and a week or so
ago I updated the RAD Update Manager. I wonder if that somehow did
something to my Eclipse 3.3 Update Manager?
Any advice on fixing this?

It sure sounds like it might have. (Everything worked before; you updated
RAD; now things don't work.)
How do you launch Eclipse? Do you specify command line arguments, use an
eclipse.ini, ...? Do you point to an explicit VM, or do you use whatever is
on the path?

I'm almost certain that is the wrong syntax. You should never have a space
in eclipse.ini. I don't remember offhand whether there's supposed to be a
newline there, a la
--launch.XXMaxPermSize
192m
or whether it's supposed to be a colon or an equals sign or something, a la
--launch.XXMaxPermSize:192m
but it's definitely not a space.

That's right - no spaces allowed. Here's my current (3.3) eclipse.ini
-showsplash
-showlocation
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vm C:\Java\JDK\1.6.0\bin\javaw.exe
-vmargs
-Xms40m
-Xmx512m

True enough. Still, hunting for unknown problems in the face of known
problems is often difficult.
Other than that issue, I don't see any problem with your launch options nor
any evidence that you're pointing to a suddenly-different VM; nor do I see
any evidence (in this one place) that installing RAD modified your Eclipse
install. That's what I was mainly looking for.
I still think that the RAD theory is a decent one, if only because it's the
only thing you've mentioned that changed in the right timeframe and that
could perhaps be related.
Is it possible for you to try creating a fresh Eclipse install and see if
the problem persists? (I recognize that if you're using the Update Manager,
you probably have a variety of additional plugins installed, so
"reinstalling Eclipse" might not be a simple proposition. But all I can do
is ask.)

You could try just extracting the Update Manager-related bundles into
your existing Eclipse installation. Make sure the versions are exactly
the same (don't extract 3.3.1 onto a 3.3 installation).

Here's the eclipse.ini that is shipped with the "JEE Developers" package
for 3.3.1:
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256M
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx512m
I think 512MB of heap should be enough for most users. Did you have to
bump it up?

I'm suggesting to re-download the Eclipse ZIP (or open it if you still
have it locally) and extract the Update Manager plugins (JARs, most
likely) into your existing Eclipse installation (in the /plugins directory).
Doing this is not generally recommended, and there is potential that you
could mess up your installation even more; but if your only alternative
is to completely re-install, this might be worth trying first since it
is a much less labor-intensive option.
Hope this helps,
Eric

You mentioned RAD 6 in some of your earlier posts. Is it possible that you
opened up your Eclipse workspace with the RAD 6 product? If so, it is
possible that this made a change to the workspace that prevents the Eclipse
update manager from working.
As another thought, have you tried to run the update manager from a
different workspace? Start Eclipse and point to a new workspace location.
You shouldn't even need to create/import any projects. Open up the Update
Manager to see if you can get past the problem.
