Fix for no-arg redirects and paging.

I experienced errors when trying to hit the controllers with no args, the redirect to the SpringBatchJobController came up with "not found" on the index action.  I omitted the action and things worked as expected.

Also, when trying to page through a long job, there was an error with a method not found due to some String args not being converted to integers.

Both fixed, and I reved the project.
