Re: java.lang.NoClassDefFoundError: com.ibm.etools.j2ee.j2eeproject.J2EENature

For the archives...
 
I got this fixed by going into the Rational Product Updater program and
doing a Rollback of "Interim Fix 004 for Rational Web Developer 6.0.1.1".  I
selected that update simply because it was the only one available to
rollback.  Note that I believe rollbacks are different from the "Revert To
Previous Version" functionality offered at what I believe to be the Eclipse
level.  After rolling back I re-updated that interim fix as I suspected it
would "fill in" the missing classes, AND IT DID!
 
Now I can get the screen shot I was needing this whole time :-)

I installed Subversion today and am not sure if that had anything to do with
the below error.  Anybody else get this and know how to fix it?  I am trying
to run the Web Services Explorer but nothing happens.  I tried to revert
back to a previous version of the workspace, but it won't allow me because
of dependencies.  Hoping I don't have to create a new workspace...
 
An internal error occurred during: "Tacit Migration Operation".
