RE: IllegalArgumentException Exception in URLDecoder

To reply to my own mail..

I put a empty try/catch block around the respective code...
and just ignored the exception when it arose..

ok.. it's a hack.. but at least it's not fallin over now..

try {
  queryString = java.net.URLDecoder.decode(queryString);
} catch (Exception e) {}

Subject: [Barracuda] IllegalArgumentException Exception in URLDecoder


Hi Guys,

I'm running into a exception...

Basically... when I submit any text containing the symbol '%', it falls
over.
E.g. 
req.getQueryString() is: p_comments=Test+%25

Which is "Test %"

I've traced it to the HttpServletRequestWrapper class, line 398.

Which says, 
queryString = java.net.URLDecoder.decode(queryString);

I think the decode function is attempting to 'decode' the string a second
time..

Help?
Regards
KD
