Possibly. If you are using a connection pool and do not close the
connection, it will not be released back to the pool, so subsequent
calls to the pool will create new connections.
There's a simple procedure to help you avoid this problem, even when errors
occur during your JDBC calls, and
Another (simpler) solution is to let someone else write that code. ;-)
I know there are times when you need JDBC directly, but tools like
iBATIS make it darn easy to handle the other 99% of the cases.
Here is a tutorial on using struts with iBATIS that could be helpful
if people are interested.

Seth,
Have you tried JDK 1.4.2? 1.4.0 has been known to have a memory leak in the

This is interesting. Can you post a bug on this to
http://nagoya.apache.org/bugzilla/ and then report back here as to what the
link to that bug is?Also, it would be ideal if you could post your
testcase (Foo.java) to that bug so people can easily reproduce the issue.
later,
Jake
