In earlier version of C4J I did some testing with 11,000 words and MySQL. I
didn't have any problem (apart from performance - which was why I switched
to using a non-relational database).

However I agree that others may have the same problem you have.

I'm not keen to implement connection pooling a C4J because then it won't
operate well in environments that already do their own connection pooling.
On the other hand I do want to fix this bug, and the connection management
system in C4J was designed to make it easy to implement connection pooling
if required.

Write a class that implements the
net.sf.classifier4J.bayesian.IJDBCConnectionManager interface, then use that
instead of DriverMangerJDBCConnectionManager

You can probably just rename the modified DriverMangerJDBCConnectionManager
to PoolingJDBCConnectionManager or something.

Could you submit this back to classifier4J? Just send the code to the list.

It makes sense to me!
