How to catch and fix this error
We have a web app running on Tomcat 5.028. When running at our company,
it works. However, it crashes (exits) at client site when access
certain page (it used to work). When we ask them to sent us the
database used and run it at our company, it works fine.
There is an Sql query in this page. Records are written out to the
page. Some records already came down before it crashes.
Please tell me how do I trouble shoot this? What kind of log can I make?
This is an urgent problem. Please help. Thank you very much for your time.

One suggestion I can give u (one which I / we follow when faced with a
similar situation) is to go to the client site (ot necessarily prod)
to debug it.
If you have used log4j then there are ways u can enable trace logging
in production and catch the problem ....
>From the looks of it - does ur webapp have to make a connection
outside the local domain (or firewall) to run the queries?

Second to posting the logs, I think these things can be different between
the two places and you might want to check.
- database access control and permission setting
- jdbc driver
- jarred lib files
- database version (or validity of sql statement for the version)
- You might also want to compare the jsp-converted-to-java files, if
relevant.
