I've reduced my real problem to a simple somepackage.CustomException example.
In my real application, there are actions, such:
<action path = "/_spikeAction_3rdLayerEx"
validate = "false"
scope = "request"
name = "spikeAction_3rdLayerEx"
type = "_spikes.ownactions.SpikeAction_3rdLayerEx">
</action>
where the action class is:
public final class SpikeAction_3rdLayerEx extends Action {
private static Logger logger =
Logger.getLogger(SpikeAction_3rdLayerEx.class.getName());
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse
response)
throws Exception {
try {
/*
* some our code that can throw checked exception....
*/
throw new Exception("3rd layer exception", new
Exception("the cause"));
} catch (Exception e) {
logger.log(Level.SEVERE, "log 3rd layer exceptions and
forward to error
page", e);
throw e;
}
// return null;
}
}
this works well, when in web.xml is:
<error-page>
<error-code>500</error-code>
<location>/ErrorPage_3rdLayer.jsp</location>
</error-page>
so the page ErrorPage_3rdLayer.jsp is displayed. But how can i configure the
environment to display mentioned error page every time when AnyException
extends Exception (or extends RuntimeException) occurs, no matter whether in
an action or jsp page simply browsed by browser?
The second problem is that i have some BaseActionForm extends ActionForm,
which has got the method validate. When an Exception (ClientException, or
RemoteException, or RuntimeException) occurs in this method, sturts don't
display error page. It is possible this situation is caused by wrong design
of the application, which is in progress of development.
