JDBC connection failing

[Barnabas Yohannes]

Folks,
We have an xml page that runs on tomcat and apache server.  After the xml
application that uses a jdbc connection to the databse.  After it runs for
about 12 hours, the page does not reply, that is, we get a page that is
trying to load but remains blank without any response for a very long period
of time.  We have a T1 connection, but till no response.

We think that it is caused by the JDBC connection after accessing it for
many times, it is failing to release the open connections.  However, this is
only our speculation.  Is there any way that we can check the JDBC
connection?

There is nothing in error logs of both apache or tomcat that is really
helpful.

Any help will be highly appreciated.

Salutations,
