I am evaluating the Liferay Portal, and Flex application support is one of the key criteria for success. While I have been able to success get a JSP/Struts portlet up and running, my flex web application (deployed as a JSP) runs independently but not as a portlet. The portal page just hangs and refuses to load completely. I cannot get anything useful from the logs.

If anyone has any working test code or pointers they can share, that will be greatly helpful!!

Thanks in advance!!

Hi

I've developed a simple flex portlet (I'm using flex 3)
(http://www.adobe. com/devnet/ flex/articles/ flex_portals_ 05.html)

But it didn't work on Liferay 4.4.2

If someone has a flex portlet working on liferay
Please send me.

Thanks in advance

Hi

I'm working with the ext environment
I've added the flex ant lib folders from "lcds" to \ext\txt-web\docroot\WEB-INF
and I've changed my web.xml like this

There are no errors when I start tomcat
but the flex part of my portlet didn't appear

Thanks.

Hi all.
I want to embed MXML code into JSP file. Please tell me how to declare . I'm developing a flex portlet but I had a problem: I added flex-bootstrap.jar lib in to /WEB-INF/lib folder and I had error: Current URL /web/guest/home generates exception: Unable to read TLD "META-INF/taglib.tld" from JAR file "file:/C:/cvsroot/lportal/ext/servers/tomcat/webapps/ROOT/WEB-INF/lib/flex-bootstrap.jar": java.lang.NullPointerException.
taglib.tld is missing. Where can I download it?

Please help me. Thank you very much.

On my Blog (http://fandry.blogspot.com), I have posted the steps necessary to create a Liferay Portlet with BlazeDS.
The Portlet access a public Web Service. I am using BlazeDS as a proxy for WebService access, but the configuration would work also for RPC/AMF, Messaging and HttpService data access.

The blog post URL is: http://fandry.blogspot.com/2008/11/liferay-portlets-using-blazeds.html

This blog is great, i sucessful integrated the flex portlet into liferay.

How can i read/acess the userid of the Liferay user in the flex mxml?

A good place to look at Personalization in Liferay is this LR forum/post post on getting User Attributes.

We (www.portletoasis.com) have successfully been able to create Flex portlets using GraniteDs (AMF channel) in Liferay. The great
thing about GraniteDs is that you can consume hibernate objects (annotated with EJB 3.0 annotations)
and fetch both eager/lazy associations from Flex. You also have the option of using Adobe LCDS on
a multi-core cpu server without charge; however, GraniteDs provides Seam integration as well
as Acegi Security.

Hi Zoltan,

The project ( liferay-portal-tomcat, Flex 3.0, and Granite 1.2.0) is interesting. Could you please give us any updates on your current project. I guess many projects will benefit a lot from your current project.

Thanks

Hello,

I apologize for taking so long to respond. As it turns out, there has been a tremendous amount of progress made in ironing out the various nuances in Flex portlet development. We've come up with 2 primary courses examining how the portlet 168 and 286 specifications intersect with using Flex to create portlets. The classes will be offered in July/August. Here is a brief rundown:

Essential Flex Portlet Development (online)
- Portlet Architecture & a Hello World Flex Portlet
- User profile information & Portlet Preferences
- Standard Role-Based Portlet Security
- Using the Flex webtier compiler for dynamic content
- Accessing Liferay's SOAP services with JSR 286 features
- "serveResource" method, action urls, etc.
- Portlet Communication: session-information and public shared render parameters.
- JSR 286 portlet events

Advanced Flex Portlet Development (onsite, scheduleable)
- Fine-grained Portlet permissions with Liferay APIs
- Integrating Liferay's Spring services with Flex
- Advanced AJAX-based portlet communication with Flex-Flex portlets / Flex-other types of portlets
- Advanced server&client-side portlet communication with BlazeDs / Java.
- Spring & EJB 3.0 (lazy-init) integration using GraniteDs.

Note: This last approach allows for Flex-data binding, deeply nested object access in Flex, and first-class
Flex classes generated from Java classes.

Both classes will give a survey of various approaches to security, data-access, data-sharing, portlet preferences, etc. In general, the portlet-compliant case is examined first, then special attention is given to Liferay-specific approaches/APIs. You should be able
to walk away with a toolbox of approaches and boiler-plate code to accomplish various tasks. You should also have an idea of a suitable approach to use for your specific situation.

Thanks,
Richard
