Hi Ray,

This is now edited and makes filter by using extended MapUtil class. I did add filter feature to MapUtil and made it PredicateFilter compatible, so these filters can be used together with ListUtil.

DynamicServletRequest API has been extended. I did add also packageinfo files, but I'm not sure if I did that correctly.

Now the DynamicServletRequest is created without intherit option and all the parameters are "dynamic" parameters, without that there where use cases that it did not work.

I'm heading how to Diamond Bar and I will be there at Monday. I'm reading my mail next time around 6 hours.

I have tested this with several test cases, so it should work.
