java - How to remove HttpServletRequest parameters (in JSP)? -

-

how can httpservletrequest parameter (especially in jsp) unset or removed (like in php using unset($_post['index']) function)? have tried following.

map requestmap=request.getparametermap(); requestmap.remove("index");

but says

no modifications allowed locked parametermap

is there way unset request parameters?

is there way unset request parameters?

afaik, not within jsp (or servlet matter).

but write filter wrapped current request in way replaces parameter map.

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
