How to receive get parameters from url in struts2

I am using struts2 & configured so the url will look like as www.myweb.com/index instead of www.myweb.com/index.action

But now the problem i am facing is how should i map in struts.xml file & get request parameters as in struts1 i can receive it through mapping.getParameters() but what available in struts2 for this?

<action path="/profile/*"
type="net.viralpatel.struts.cleanurl.ProfileAction"
parameter="{1}">
<forward name="success" path="/profile.jsp" />
<forward name="fail" path="/profile.jsp" />
</action>

String parameter = mapping.getParameter();

So in struts2 if i hit www.myweb.com/index/p=2 www.myweb.com/index/biz/name /here biz & name are 2 parameters/ www.myweb.com/index/biz/name/23 /here biz & name & 23 are parameters/

Thanks

You can use wildcard patterns to pass the parameter.

<action name="/profile/*" class="net.viralpatel.struts.cleanurl.ProfileAction">
 <param name="id">{1}</param>
<result>
  <param name="location">/profile.jsp</param>
  <param name="id">{1}</param> 
</result>
 </action>

You can also use Named Parameter

<constant name="struts.patternMatcher" value="namedVariable"/>


@Namespace{"/users/{userID}");
public class ProfileAction exends ActionSupport {
private Long userID;
public void setUserID(Long userID) {...}
}

if the request URL is /users/10/detail, then the ProfileAction will be executed and its userID field will be set to 10.

Parameters after the action name

To use parameters in the URL, after the action name, make sure this is set:

 <constant name="struts.enable.SlashesInActionNames" value="true"/>
 <constant name="struts.mapper.alwaysSelectFullNamespace" value="false"/>

Then the action mapping will look like:

 <package name="edit" extends="struts-default" namespace="/edit">
 <action name="/profile/*" class="net.viralpatel.struts.cleanurl.ProfileAction">
    <param name="id">{1}</param>
    <result>/profile.jsp</result>
 </action>   
 </package>

When a URL like /edit/profile/123 is requested, ProfileAction will be called, and its "id" field will be set to 123.

Use the patternMatcher, wildcards are for doing something else.

http://struts.apache.org/2.x/docs/wildcard-mappings.html

Using the REST plugin is another option, or the regex matcher, depending on your needs.
