/**
* <!-- START SNIPPET: javadoc -->
*
* Default action mapper implementation, using the standard *.[ext] (where ext
* usually "action") pattern. The extension is looked up from the Struts
* configuration key <b>struts.action.extension</b>.
*
* <p/> To help with dealing with buttons and other related requirements, this
* mapper (and other {@link ActionMapper}s, we hope) has the ability to name a
* button with some predefined prefix and have that button name alter the
* execution behaviour. The four prefixes are:
*
* <ul>
*
* <li>Method prefix - <i>method:default</i></li>
*
* <li>Action prefix - <i>action:dashboard</i></li>
*
* <li>Redirect prefix - <i>redirect:cancel.jsp</i></li>
*
* <li>Redirect-action prefix - <i>redirect-action:cancel</i></li>
*
* </ul>
*
* <p/> In addition to these four prefixes, this mapper also understands the
* action naming pattern of <i>foo!bar</i> in either the extension form (eg:
* foo!bar.action) or in the prefix form (eg: action:foo!bar). This syntax tells
* this mapper to map to the action named <i>foo</i> and the method <i>bar</i>.
*
* <!-- END SNIPPET: javadoc -->
*
* <p/> <b>Method Prefix</b> <p/>
*
* <!-- START SNIPPET: method -->
*
* With method-prefix, instead of calling baz action's execute() method (by
* default if it isn't overriden in struts.xml to be something else), the baz
* action's anotherMethod() will be called. A very elegant way determine which
* button is clicked. Alternatively, one would have submit button set a
* particular value on the action when clicked, and the execute() method decides
* on what to do with the setted value depending on which button is clicked.
*
* <!-- END SNIPPET: method -->
*
* <pre>
* <!-- START SNIPPET: method-example -->
* <s:form action="baz">
* <s:textfield label="Enter your name" name="person.name"/>
* <s:submit value="Create person"/>
* <s:submit name="method:anotherMethod" value="Cancel"/>
* </s:form>
* <!-- END SNIPPET: method-example -->
* </pre>
*
* <p/> <b>Action prefix</b> <p/>
*
* <!-- START SNIPPET: action -->
*
* With action-prefix, instead of executing baz action's execute() method (by
* default if it isn't overriden in struts.xml to be something else), the
* anotherAction action's execute() method (assuming again if it isn't overriden
* with something else in struts.xml) will be executed.
*
* <!-- END SNIPPET: action -->
*
* <pre>
* <!-- START SNIPPET: action-example -->
* <s:form action="baz">
* <s:textfield label="Enter your name" name="person.name"/>
* <s:submit value="Create person"/>
* <s:submit name="action:anotherAction" value="Cancel"/>
* </s:form>
* <!-- END SNIPPET: action-example -->
* </pre>
*
* <p/> <b>Redirect prefix</b> <p/>
*
* <!-- START SNIPPET: redirect -->
*
* With redirect-prefix, instead of executing baz action's execute() method (by
* default it isn't overriden in struts.xml to be something else), it will get
* redirected to, in this case to www.google.com. Internally it uses
* ServletRedirectResult to do the task.
*
* <!-- END SNIPPET: redirect -->
*
* <pre>
* <!-- START SNIPPET: redirect-example -->
* <s:form action="baz">
* <s:textfield label="Enter your name" name="person.name"/>
* <s:submit value="Create person"/>
* <s:submit name="redirect:www.google.com" value="Cancel"/>
* </s:form>
* <!-- END SNIPPET: redirect-example -->
* </pre>
*
* <p/> <b>Redirect-action prefix</b> <p/>
*
* <!-- START SNIPPET: redirect-action -->
*
* With redirect-action-prefix, instead of executing baz action's execute()
* method (by default it isn't overriden in struts.xml to be something else), it
* will get redirected to, in this case 'dashboard.action'. Internally it uses
* ServletRedirectResult to do the task and read off the extension from the
* struts.properties.
