Subject [jira] Updated: (BEEHIVE-1130) ClassCastException in the DefaultExceptionsHandler when handling JSP rendering exceptions on a direct call to a JSP
Date Mon, 25 Jun 2007 20:45:26 GMT

     [ https://issues.apache.org/jira/browse/BEEHIVE-1130?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Russ Baker updated BEEHIVE-1130:
--------------------------------


Verified that the exception is handled correctly and neither a ClassCastException nor an AssertException
is not thrown. The exception goes through the ExceptionHandler like it should and is handled
by the code in that handler. Verified against SVN 549584 using Carlin's example.

> When a request is made directly to a JSP (not via a page flow) and the rendering of the
JSP throws an exception, the PageFlowPageFilter will catch the exception and try to use the
DefaultExceptionsHandler. However, the DefaultExceptionsHandler expects the request to be
a PageFlowRequestWrapper and calls PageFlowRequestWrapper.get(). In this scenario, the request
is not a PageFlowRequestWrapper so the get() method throws either an AssertException (when
checking for the PageFlowRequestWrapper) or a ClassCastException when running without asserts.
