Nope, they are different critters. A journal can catch file
transaction integrity issues (e.g. if you write data to extend a file,
a journal can make sure the length is updated in the inode).

What a journal cannot catch is corruption in the metadata due to other
things besides transaction integrity issues, such as flakey hardware
causing a write to the wrong sector.

A journal will not catch a dieing hard drive; fsck can.
