Assuming you meant to type version 5.6 and not 3.6, check to see if
you have a file called "grappa1_2.jar" in your "lib" directory.  This
is where the offending class should be found.  If it is not there, did
you build your own eclipse or are you using one of the tarballs from
the web-site?  If so, which one?
