How do I add custom error pages?
...
There are also some other neat settings you should check out in getApplicationSettings()
, getDebugSettings()
, getExceptionSettings()
, getMarkupSettings()
, getPageSettings()
, getRequestCycleSettings()
, getSecuritySettings
and getSessionSettings()
. See the javadoc for more information.
If calling setInternalErrorPage()
, make sure to also call:
Code Block |
---|
// show internal error page rather than default developer page getExceptionSettings().setUnexpectedExceptionDisplay(IExceptionSettingsExceptionSettings.SHOW_INTERNAL_ERROR_PAGE); |
...
This is assuming that you have mapped "/404" in your WebApplication:
Code Block |
---|
mountmountPage(new HybridUrlCodingStrategy("/404", PageNotFound.class)); |
In your error WebPage:
Code Block |
---|
public class PageNotFound extends WebPage { private static final long serialVersionUID = 1L; public PageNotFound() { // Add any necessary components } @Override protected void configureResponse() { super.configureResponse(); getWebRequestCycle().getWebResponse().getHttpServletResponse().setStatus(HttpServletResponse.SC_NOT_FOUND); } @Override public boolean isVersioned() { return false; } @Override public boolean isErrorPage() { return true; } } |
...
Code Block |
---|
// also see AbortWithWebErrorCodeException and AbortWithHttpStatusException
throw new AbortWithHttpStatusException(404, true);
|
For wicket 6 and beyond:
Code Block |
---|
throw new AbortWithHttpErrorCodeException(404, "Some message");
|
Overriding All Error Pages for RuntimeException
...
Code Block |
---|
public final class MyRequestCycle extends WebRequestCycle { /** * MyRequestCycle constructor * * @param application the web application * @param request the web request * @param response the web response */ public WebRequestCycle(final WebApplication application, final WebRequest request, final Response response) { super(application, request, response); } /** * {@inheritDoc} */ @Override protected final Page onRuntimeException(final RuntimeExceptionPage ecause, final PageRuntimeException causee) { // obviously you can check the instanceof the exception and return the appropriate page if desired return new MyExceptionPage(e); } } |
...
Code Block |
---|
getSession().error(message);
throw new RestartResponseException(MyErrorPage.class, optionalPageParameters);
// use RestartResponseAtInterceptPageException(MyErrorPage.class);
// instead to interrupt current request processing and immediately redirect to an intercept page
// it may be tempting to do the following, but it should not be done:
// error(message);
// setResponsePage(MyErrorPage.class);
// Why not?
// What about this; will it work? (My experience says no, but I don't know why not.)
// getSession().error(message);
// setRedirect(true);
// setResponsePage(MyErrorPage.class);
