t5: intercepting exceptions from RequestExceptionHandler
Hi,
I have url like this:
http://localhost/display/ZmM%3D
but seems it will reject the parameter that has an equal sign even it is
urlencoded:
[ERROR] RequestExceptionHandler Processing of request failed with uncaught
exception: Input string 'ZmM=' is not valid; the character '=' at position 4
is not valid.
questions:
1) is there a way to let t5 accept the equal sign as part of url parameter?
2) how to intercept this exception in code?
Thanks,

Hi Thiago,
You are right, the easiest way is to override that URLEncoder service, need
only add this:
markSafe("01234567890-_.:=");

In the upload request issue, I put:
public static void
contributeHttpServletRequestHandler(OrderedConfiguration<HttpServletRequestFilter>
configuration, MultipartDecoder multipartDecoder)
{
configuration.add("UploadRequestFilter", new UploadRequestFilter(),
"before:MultipartFilter");
}
but in this case, where should i put? of course not
"before:multipartFilter".

Hi Thiago,
I have code before, that was used to intercept file upload exceptions, can
we use similar approach to intercept this exception too?
public class UploadRequestFilter implements HttpServletRequestFilter {
final private Logger logger;
public UploadRequestFilter(Logger logger) {
this.logger = logger;
}
public boolean service(HttpServletRequest request, HttpServletResponse
response,
HttpServletRequestHandler handler) throws
IOException {
boolean result = true;
try {
result = handler.service(request, response);
} catch (RuntimeException e) {
Throwable err = e.getCause();
logger.info(err.getMessage());
if (err instanceof
FileUploadBase.FileSizeLimitExceededException) {
response.sendRedirect("/info/filesizeproblem");
} else if (err instanceof FileUploadBase.IOFileUploadException)
{
logger.error("looks like time out error");
try {
throw err;
} catch (Throwable throwable) {
throwable.printStackTrace();
}
} else {
}
}
return result;
}
}

As an alternative to overriding, decorating RequestExceptionhandler
might allow you to do what you want.

One solution is to override the
org.apache.tapestry5.services.URLEncoder service.
To intercept exceptions, you'll need to override the
RequestExceptionHandler service.

Hi Thiago,
My problem is, those links are already distributed, can't be changed, if I
can intercept this exception then I can redirect the process, any idea how I
can intercept that exception?
Thanks,
Angelo

I guess many people are having problems with the new URL decoding used
by Tapestry since 5.0.16 (or some version near this one) as it does
not accepts some valid URL encoded values. Angelo, while this is not
solved in Tapestry itself, you can try changing your URL to
/display?ZmM%3D and get the value through
HttpServletRequest.getQueryString().
