Check your error.log  in Apache/logs which shows errors in this format.....

SQLException: [interclient][interbase] arithmetic exception, numeric
overflow, or string truncation

and then check the Jserver/logs/mod_jser.log which stores errors on this
format....

[20/10/1999 10:25:20:397] (ERROR) ajp11: Servlet Error:
java.lang.NullPointerException: null
[20/10/1999 10:25:20:397] (ERROR) an error returned handling request via
protocol "ajpv11"

Not definitive.... Just do try's n Catch's and put the error to a string.
 and then return the string on the HTML page.  Just for debugging purposes.


Hope this helps.
