portlet

I'm trying to create portlet in liferay with just only from a JSP file called view.jsp . What I need is: When the portlet loads, I want to call custom Java class where I generate an array. I need to pass that array to the view.jsp . How to do that? Have you created your portlet with the create.sh script from Liferay? In this case, we will need to create a new portlet class that extends MVCPortlet : public class ArrayPortlet extends MVCPortlet { } Also, you will have to change the WEB-INF/portlet.xml file to point to its class. Replace the line below by <portlet-class>com.liferay.util.bridges

I am asked to work on portlets and portals. I want to know the difference between a portlet and a servlet? How / where does a portlet differ (may be functionally) from a servlet? Portlets are part of JSR-168 standard that regulates portal containers and components. This is different standard from standards for web containers (and servlets). Though there are definitely strong parallels between these two standards they differ in containers, APIs, life cycle, configuration, deployment, etc. The main difference between portlet vs. servlet could be that while servlet always responds to single type

I want to run some code as soon as my plugin ( portlet , hook or theme ) is available in Liferay. I can't find anything like a startup listener in liferay-plugin-package.xml , liferay-portlet.xml , liferay-hook.xml or liferay-look-and-feel.xml . There is another way. You could utilize the StartupAction. It is merely an Event, which get's triggered on every startup of a plugin. This method will only get triggered once on a server start or deploy. Recognize, that the doRun method get's a String array of companyIds as an argument. A companyId is representing a portal instance (the Liferay

I am trying show a portlet (that previously I have created) from another one, but the pop-up is empty. First, I create the renderURL: <liferay-portlet:renderURL var="testPopupURL" portletName="<%=rule.getBannerPortletId() %>" windowState="<%=LiferayWindowState.POP_UP.toString() %>"></liferay-portlet:renderURL> and I do the link: <aui:a href="#" onClick="showPopup('${testPopupURL}')">View</aui:a> and this is the function showPopup: function showPopup(url){ console.log("En el showPopup "); AUI().ready('aui-dialog', 'aui-io', 'event', 'event-custom', function(A) { window.myDialog = new A.Dialog({

How to show error message in liferay portal? I read on liferay.com site that for show error message I can use liferay-ui:error tag from tag library, but it's not working, how to use it? Jonny You are right in about "liferay-ui:error" tag so on your JSP you will have: <%@ taglib uri="http://liferay.com/tld/ui" prefix="liferay-ui" %> <liferay-ui:error key="some-error" message="Your error message goes here!" /> Then in your Java code you will need either the RenderRequest or ActionRequest normally however any type of HTTPServletRequest or PortletRequest can also be used. Then you pass your

I have faced problems in trying to install new portlets to Liferay running on Glassfish domain. I figured out the flow very lately and want to share it with others also. So, please read the answer and hope this helps someone :) (Pre requisites for the problem is that I knew that adding projects running on Glassfish is done with a autodeploy folder, but making them visible on Liferay was another story.) So, you make first a .war file let's say a portlet of name your_file.war. You wanna have it running on a glassfish domain under Liferay portal. Steps to success: 1) Navigate to Control Panel ->
