you might also check out C-JDBC from ObjectWeb. Emmanuel Cecchet did a writeup for Derby that's available for download from here:

Hi,

We use a derby server in an High Availability context. Thus, we need to test if derby server is in a good shape or not. The result of this repetitive question will imply a fail-over or not.

we thought about two solutions:

1/ create an agent to insert/select/delete an entry in a table
2/ create a stored procedure doing a finer job.

these solutions do not satisfy us as:

o a JVM needs to be created for a very short duration and repetitively
o it's CPU consuming.

So, do you think of another solution that would prove the derby server is in a good shape, without consuming too much resources.

Thanks
