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

[12年前 に Ravi Kiran によって更新されました。]

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 ??
