Fabien,
Just a follow-up to my previous email.
I was able to get the calling URI of the page that caused the exception
along with the time of the exception to be stored in the application log of
Tomcat (or your webapp).
In my error page (error.jsp) I put:
<% // Log the calling URL to the log file. All other info about the
exception is logged automatically.
application.log("Exception occured on page-> " + (String)
request.getAttribute("javax.servlet.error.request_uri"), exception);
%>
This placed the calling URI and date/time in my log file as shown:
2001-11-17 01:14:26 Exception occured on page-> /rfq/inqtableman.jsp
java.sql.SQLException: Error during query: Unexpected Exception:
java.sql.SQLException message given: Column not found: Unknown column
'inqmain.inqNumberZZZ' in 'order clause'
at org.gjt.mm.mysql.Connection.execSQL(Connection.java:807)
at org.gjt.mm.mysql.Connection.execSQL(Connection.java:740)
at org.gjt.mm.mysql.Statement.executeQuery(Statement.java:159) . . . . . .
. (much more information written by Tomcat)
The above example is for an SQL exception, and you must have the exception
and error page defined in the web.xml file of your web application.
I did not need the code in the calling page that I wrote in the previous
email.
BTW I am using Tomcat 4.0, W2K
Hope this helps,
Barry
