------- Additional Comments From vgritsenko@apache.org  2005-10-06 12:12 -------
You missed several things:

1. Since Cocoon 2.1.8 (not released yet), SQLTransformer re-uses connection for
nested queries, if possible. In your example, it will use 1 connection per
request, and will not block.

2. Even if you do require multiple connections, connectAttempts and
connectWaittime are configurable - see transformer docs.

3. Database connection pool can be configured either to block (and wait), or to
throw exception immediately if no connections are available in the pool.

Make sure you have properly configured both pool and transformer, and get latest
transformer version from the SVN.
