Thread-Topic: Change in JSP error handling in Tomcat5.0??

Subject: Change in JSP error handling in Tomcat5.0??

Hi.

While testing a JSP error page that was working fine 9 months ago, I =
found that the page is not now performing its function.
Instead of displaying an appropriate error message when the associated =
JSP receives alphabetic data instead of the integer data
that it is expecting, an HTTP 500 message saying that the data =
manipulation JSP cannot be displayed is generated by the browser.=20

The simple application behaves fine when valid data is entered, and the =
JSP error page itself can be rendered directly (if a
suitable check is made for the implicit object 'exception' being equal =
to null).

Here is the (very ordinary) error page declaration line in the data =
manipulation JSP:
<%@ page errorPage=3D"AdderError.jsp" %>

Here is the (equally ordinary) associated line in the JSP error page:
<%@ page isErrorPage=3D"true" %>

The only changes that have taken place since I last tested these pages =
are the replacement of Java SDK1.4.2 with SDK1.5.0/5.0 and
the replacement of Tomcat 4.1 with Tomcat 5.0.

It seems highly unlikely that the change of SDK could have led to this =
problem, but I suppose that there may be some change to
Tomcat (or, more likely, version 2.4 of the servlet API) that has passed =
me by.

Can anybody shed light on the cause of this change in behaviour?

Any assistance would be greatly appreciated.

Cheers.
Jan
