How to create renderURL

<%
 PortletURL renderUrlFromJSP = renderResponse.createRenderURL();
 renderUrlFromJSP.setParameter("param1", "This portletULR is created with API in JSP");
 renderUrlFromJSP.setWindowState(LiferayWindowState.NORMAL);
 renderUrlFromJSP.setPortletMode(LiferayPortletMode.VIEW);

%>
<a href="<%=renderUrlFromJSP%>">Render Url created by JAVA API in JSP</a>



How to create ActionURL from renderResponse object

<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>
<%@page import="javax.portlet.PortletURL"%>
<portlet:defineObjects />
<%
    PortletURL actionURL = renderResponse.createActionURL();
    actionURL.setParameter("javax.portlet.action", "someProcessAction");
%>

<a href="<%=actionURL%>">Call Process Action</a>

@ProcessAction(name="someProcessAction")

public void someProcessAction(ActionRequest actionRequest, ActionResponse actionResponse){

String value = ParamUtil.getString(actionRequest, "some-parameter");

    System.out.println("#######Calling some process action##############");

}

This is the easiest way to create action URL. For example

<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>

<portlet:defineObjects />

<portlet:actionURL var="actionURL" name="someProcessAction"/>

 <a href="<%=actionURL%>">Call Process Action</a>
