Java Concepts

Hi, Below is the code ,to create the different types of request URL. As we know in Liferay we have 3 types of URL 1.ActionRequest 2.RenderRequest 3.ResourceRequest. //Create Render URL PortletURL renderURL = PortletURLFactoryUtil.create( actionRequest,PortalUtil.getPortletId(actionRequest), themeDisplay.getLayout().getPlid(), "0"); renderURL.setParameter("customparam","customvalue"); actionResponse.sendRedirect(renderURL.toString()); If you want to create the ActionRequest put 1 instead of 0 in the last argument. We can check the code in the  PortletURLImpl class of liferay if (_lifecycle.equals(PortletRequest.ACTION_PHASE)) { _reservedParameters.put("p_p_lifecycle", "1"); } else if (_lifecycle.equals(PortletRequest.RENDER_PHASE)) {

Creating the Resource URL Liferay's default uses the resource url for ajax requests          <portlet:resourceURL id="addResource" var="addResourceURL">         </portlet:resourceURL> Creating the Ajax function creating the Jquery  ajax function function <portlet:namespace/>getEntries(){                 var url = "${addResourceURL}";                         $.ajax({                                 type : "POST",                                 url : url,                                 dataType : "JSON",                 ...

Sometimes it may requires to create URL in Javascript. In Liferay we can create any URL in Javascript.  In Normal Case we can create Action URL as            < portlet:actionURL var="testURL" name="update" /> In Javascript we create as           <aui:script>            AUI().ready('liferay-portlet-url', function(A){           var actionURL = Liferay.PortletURL. createActionURL ();          actionURL .setParameter("cmd", "test");            });          </aui:script>    To create renderURL we put as Liferay.PortletURL. createRenderURL() ; in above script.    To Create resourceURL we put as Liferay.PortletURL. createResourceURL() ; Refer "LiferayPortletURL" interface to get more idea. Apart from the setting the parameter(...
