You need to do simply request.getParameter("parameterName"); if you extend MultiActionController. To utilize setCommand() extend SimpleFormController

Update (for more understanding upon getParameter() method ) :

Suppose you have a form like this :

<form action="myController.html" method="post">
    Name : <input type="text" name="username" value="${param.username}" />
    <%--
       That ${param.username} will help pre-populating the value 
       of the text field with `username` parameter
    --%> 
</form>

And in your controller method, retrieve the submitted parameter like :

public ModelAndView myControllerMethod(HttpServletRequest request, HttpServletResponse response) {
    String username = request.getParameter("username");
}

As said, you cannot use bean with extending MultiActionController, you need to do it for all the bean attributes individually.
