"Unknown share" error adding project to jazz sourc

Attempting to share a simple project with jazz source control. The
project was imported into eclipse from "c:\" using the
import -> "Existing projects into workspace".

Once imported, I right clicked on the project and chose Team->Share
Project.

I complete all the pages into the wizard, leading up to the
"Share Project in Jazz" page. Then I verified the project I
wanted to import is still selected- it was.

Clicking "next", I'm presented with the Review Ignored
Resources page in the wizard. I check the "show all
resources" checkbox. When I expand the contents of the project
to identify the Matching Resources to ignore, I get a dialog with the
title "Problem Occurred" and a message, which reads:
"An error has occurred. See error log for more details.
java.lang.IllegalArgumentException". When I click on Details, I
see another error: "An error has occurred. See error log for
more details. Unknown share C:/".

There are no further details in the error log.

When I select elements from the Matching Resources list and click
Ignore, I get the "Add to Ignore List" dialog with the list
of selected resources listed in the "Ignored Resources"
section, highlighted in red. Each entry has a message stating
"not matched". It's as if it can't resolve the location of
the files on the file system.

Any help on why this is failing? This was supposed to be a simple test
of getting a project from disk to jazz.

I've never encountered this problem ... you'll probably need to work
with Rational support on this. This is (as you can imagine) a very
frequently used operation, so there must be something rather unusual
going on with your configuration/installation.
