Hi,
I try to implement an application specific exception handling. Therefor I
created a class that extends ExceptionHandler and my own Exception class that
has variables for holding an error code and the filename where the exception
occured.
When I generate a NullPointerException I generate a new object of my exception
class an throw it. Unfortunately, in the exception handler class I only see
an object of class Exception. So, I'm not able to get the error code and the
filename from the exception object. When I try to cast the exception
explicitly to my exception class I get a ClassCastException.
How can I get an object of my own exception in the exception handler?
Regards,
Ralf.
struts-config.xml:
<global-exceptions>
<exception handler="de.fortu.actions.FortuExceptionHandler"
type="java.lang.Exception"
key="global.error"
path="/jsp/error/error.jsp"
scope="request" />
</global-exceptions>
ExceptionHandler Class:
public class FortuExceptionHandler extends ExceptionHandler
{
public ActionForward execute (Exception ex, ExceptionConfig config,
ActionMapping mapping, ActionForm formInstance,
HttpServletRequest request,
HttpServletResponse response)
throws ServletException
{
String property = null;
String path = null;
if(config.getPath() != null)
path = config.getPath();
else
path = mapping.getInput();
ActionForward forward = new ActionForward(path);
ActionError error = new ActionError("global.error.nosession");
storeException (request, property, error, forward, config.getScope());
return forward;
}
}
