Q:

How to submit a valid user request to Liferay Default Landing Page

I am using Liferay 6 .

I have created a page and added 6 portlets to it and configured inside portal-ext.properties file as
auth.forward.by.last.path=true
default.landing.page.path=/user/test/home
This private page with all my 6 portlets is  shown only  when i use Liferay's sign in Portlet (The default login page of Liferay )
Similarly i have my Custom Portlet  made of struts2 , which is shown on entering http:localhost:8086 as shown below

<s:form action="helloForm" method="POST" theme="simple">
    Enter Your Name:<s:textfield name="namer" />
    Enter Your Name:<s:textfield name="passer" />
    <s:submit/>
</s:form>

Currently , when user clicks on submit the Struts2 Action class recivies that as shown 
public String execute() throws Exception {
    HttpServletRequest request = ServletActionContext.getRequest();
    String name = ParamUtil.getString(request, "namer");
    //  does Database check and decides the return page 
    return ActionSupport.SUCCESS;         
}

Now my requirement is that , if he is a valid user , i want to redirect him/her to the Landing Page configured 
Please tell me how to do this ??

A:

HttpServletResponse response = ServletActionContext.getResponse();
String targetUrl = "/user/test/home";
response.sendRedirect(targetUrl);
