Patterns can optionally be matched "loosely". When the end of the pattern matches *[^*]*$ (wildcard, no wildcard, wildcard), if the pattern fails, it is also matched as if the last two characters didn't exist. The goal is to support the legacy "*!*" syntax, where the "!*" is optional.

In the action mapping and action results, the wildcard-matched values can be accessed with the token {N} where N is a number from 1 to 9 indicating which wildcard-matched value to substitute. The whole request URI can be accessed with the {0} token.

<constant name="struts.mapper.alwaysSelectFullNamespace" value="false"/>
<constant name="struts.patternMatcher" value="regex" />
