Hi,
the grid submission via glite does not work anymore, since the CMS glite servers were switched off.
You can submit to selected grid sites directly via the CREAMCE backend, but you need their CE URL (Which can be found with "lcg-infosites ce").
If you want to submit to the CMS resources on the grid, you need to sign up to "CMS connect" and use some experimental patches at the moment.
Cheers,
Fred
