set different attribute according to the change of parameter

Can I do the following?

Same action class sets different attribute
according to the change of parameter?

Thanks

<action path="/userProfileMaint"
	type="com.erp.struts.SetRoleHref"
	parameter="userProfileMaint"

<action path="/quotationMaint"
	type="com.erp.struts.SetRoleHref"
	parameter="quotationMaint"

public class SetRoleHref extends Action {
	    String myValue = request.getParameter("parameter");
	    session.setAttribute("rolehref", myValue);

My action class like this

public ActionForward userProfileMaint (ActionMapping mapping,
		ActionForm form,
		HttpServletRequest request,
		HttpServletResponse response) throws Exception {
		HttpSession session = request.getSession();	
		session.setAttribute("rolehref", "userProfileMaint");
		return mapping.findForward("success");
	}

my struts-config.xml

	<action path="/userProfileMaint"
	type="com.erp.struts.SetRoleHref"
	parameter="userProfileMaint"
	scope="request">
	<forward name="success" path="user.showRoleProgram" />
	</action>

The result is
javax.servlet.ServletException: Request[/userProfileMaint] does not
contain handler parameter named 'userProfileMaint'. This may be caused
by whitespace in the label text.

What can I do?

Should the parameter be passed into Action class by
http://xxx/foo?a=b ?

Can the Action class get the parameter value
and the link is http://xxx/foo only?

I do not want the parameter appear in the URL.

Thanks

Sure, you can do that, except that the 'parameter' attribute in the 
action mapping isn't exposed as a request parameter (those come from the 
  HTTP request). You need to call getParameter() on the ActionMapping 
instance instead.
