Hi! We are discussing whether it's a good idea to switch from plain portlet development on a liferay installation to spring webmvc portlet based development. We're starting the development of some portlets soon, so now is the time. But the problem I see is that we'd like to use some of the portlet 2.0 features, which won't work with ve...
I am trying to use Public Render Parameter to inter portlet communication. I have PorteltA and PortletB on Submit of PortletA ( processAction) sets render parameter "city" which is defined in portlet.xml. PortletB gets "city" parameter in doView() and display on view jsp.

I have tried the following ways: response.setCharacterEncoding("ISO-8859-1") ; PrintWriter out = resWrapper.getWriter(); out.println("á"); out.close(); OR response.setContentType("text/plain; charset=ISO-8859-1"); PrintWriter out...
Hi Guys, I have worked with Websphere Portal 6.0,6.1 and developed portal applications usign JSR 168,JSR 286 Portlets.

But want to know what are the major difference at...
On a Java portal you can have portlets that include data provided by other applications. We want to replace our existing Java portal with a Django application, which means duplicating the Java portal's ability to display portlets. The two Sun specifications in question that we want to duplicate are JSR168 and JSR286. I need a cPython so...
Does Spring 3.0 Portlet MVC really support JSR-286 aka Porlet 2.0? I've seen anecdotal mentions of it but nothing in any documented form. If so, has anyone successfully implemented a JSR-286 plugin with Spring 3.0. If yes, on what platform? Any good reference information, or better yet, a sharable implementation? ...
I get the following exception when deploying a JSR 286 portlet into Oracle WebLogic Server 11g (to deploy it later in Oracle WebCenter 11g): <19-ene-2010 13H32' CET> <Error> <oracle.portlet.server.containerimpl.PortletApplicationImpl> <BEA-000000> <Error al procesar el archivo "/WEB-INF/portlet.xml" en la lÝnea 6 columna 68. org.xml.sax...
I am trying to build something "portlet server"-ish on the google app engine. (as open source) I'd like to use the JSR168/286 standards, but I think that the restrictions of the app engine will make it somewhere between tricky and impossible. Has anyone tried to run jetspeed or an application that uses pluto internally on the googl...
I know that Spring 3 supports JSR-286 (portlets version '2.0'). However I can't find a lot of documentation on that. Can anyone share some links about this? Thank you. ...

Hi, I am new to portlets and have a question about how they work in CMS portals ( we are evaluating LifeRay as a CMS ). Let's say, for example, I would like to create a portlet to display all the books required for a particular course. You don't have to be logged in to see this, it will appear on public website. In the CMS, I will cre...
I want to use displaytag in my jsr 286 portlet but it gives exception. Can anyone provide me examples for using display tag with portlet as I could not found any examples through googling. ...
The Java world has a JSR-286 standard for how portals and portlets should interoperate: software components sharing a unified web page. There seem to be a number of portal implementations. But is there a live "marketplace" of interchangeable portlets that will run in them? From what I can find searching the web, it looks very lopsided -...
Hi, is it possible to implement IPC with GWT2 Portlets? Preferably i'd like to use the JSR286 Event mechanism, but would have to do so out of the GWT Portlets. I am using a Liferay 6 Portal. Has anyone any experience with this kind of environment? thanks for your help, stefan ...
Hello, I'm trying to use external paging in a JSR-286 portlet with DisplayTag 1.2. I would like DisplayTag to generate the paging links from a parameterized Action URL that i have defined, but i can't seem to make that work. Here is the code in my JSP: < portlet:actionURL var=actionUrl > < portlet:param name="someParam" value="someVal...
We've been given a requirement that our new project be JSR 286 compliant so that it can eventually be hosted in SharePoint. But in the same breath we were told that we're not being asked to write a portlet. Just be compliant with the standard. We were originally thinking of using Struts 2 and just writing a normal application. Does t...
