portlet

问题 Is it possible to create widgets / portlets in GWT that can be dynamically loaded and added to a GWT web application, and where the GWT widgets can reside in a separate war files? To clarify my question: JSR168/JSR286 compliant portals make it possible to create portlets in separate projects (war files) and to dynamically load these into a portal page. Suppose you want to do something similar in a GWT application. So suppose we made a portal using only GWT for the GUI (no JSP or alike) and we

问题 We have something called nested portlets in liferay. I want to add this portlet dynamically through code. Does anyone know the code for adding nested portlets, and add other portlets inside it? Thanks !!! 回答1: for complete example i'll assume that you want to add nested portlet to current page using another portlets action handler. (if used from render action you would not see nested portlet until next view of the page) Add these methods to your code private static String addPortlet(final

问题 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? 回答1: 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

问题 Led by this comment in a previous question: Portlet: Forward a ResourceRequest to show the full portal I was wondering if the best way to generate a dynamic download from a portlet (Like, for example, a dynamically generated PDF or image), is making a ResourceRequest, or if there is a better alternative approach 回答1: The purpose of ResourceRequests and the serveResource method is to offer a way to serve resources or content fragments. So, yes, using ResourceRequests is a valid way to

问题 I'm having this issue while developing portlets: Caused by: javax.servlet.ServletException: java.lang.AbstractMethodError: javax.servlet.jsp.PageContext.getELContext()Ljavax/el/ELContext; I don't know anymore, what I can do.

问题 I'm trying to implement the Form Runner Proxy Portlet into my Liferay portal but I have a problem. In Orbeon, I have an application named "CUS07" and two forms named "CUS07" and "Test" (and Orbeon default app and forms). I set the init parameters in "portlet.xml" to display "CUS07/CUS07" form by default. It's working well. But when I go to the "Preferences" page in the portlet configuration and I set "Form Runner app name" to "CUS07" and "Form Runner form name" to "CUS07" and click on "Save"

For portletId I tried String portletId = ((PortletConfigImpl) portletConfig).getPortletId(); but it seems I can't. Guess it is because the impl is in another jar not meant to be accessed from portlets By the way, my main goal is to get to pass both params to another non-request context so I can do final PortletPreferences
