Schema Comparison

I need to compare 2 mysql database schemas (tables, columns, used data types, keys, constraints) and would like to have the differences displayed.
Is there any free tool that can be run from the command line and which generates a report? Or is there a nice Java API which I can use? I know, there is some useful stuff in java.sql... where I would still need to do some programming to get what I need... I only want to do this if there is no other solution.
Thanks a lot in advance.

The "procedure" I use is to create a schema export in both databases and run the UNIX "diff" command against them.

Yes, the diff solution is the easiest, but not the nicest because it doesnt tell you "contraint xyz is missing" for example...
I agree. Here's the link:
