Java EE (Java Enterprise Edition) General Discussion

Hi. I got a HTML form that allows a user to enter freehand SQL statements and send them to an DB2 database via a SQL Java servlet. After the query executes, it returns an Excel file containing the resultset of my query. Unfortunately, I got a query that when executed, my browser returns "The page could not be found..." due to connection timeout. With another query with different set of criteria, it runs fine-so my Tomcat is running fine. I've executed the same exact query in Excel via JDBC-ODBC bridge Java application and it ran fine and also executed the same query in QMF for Windows, and it ran fine also. So this lends me to believe I need to configure my Tomcat somehow, I presume the connection timeout limit.

Is there a way to remove or increase the connection timeout limit?
Thanks in advance.
