Laszlo View

[fmourioux]

Hi,

A simple question : is there someone working on a Laszlo View for spring ?

For people who doesn't know Laszlo, it is like Macromedia's Flex, but it is now opensource ;-)

Take a look at http://www.laszlosystems.com/

Yes, it looks quite good from the 10 minute preview and demo apps.

you're right i put the direct link for the orthers : http://www.laszlosystems.com/lps/laszlo-in-ten-minutes/

I had a quick look at the Laszlo site and what I could see from the architecture docs, the main interface from LPS is through LPS Data connector (SOAP/XML - Web Services).

Do you know if there are other ways to interface with LPS - that is talk to a Spring service layer ?

It looks nice when you browse the sample code. If I understand it correctly LPS is a Client/Server platform that specializes on client experience of look and feel using Flash player technology.

Fabien, have you used LPS outside of the Spring framework? It would be nice if we could find a good integration point to a Spring Service layer.

Hi Hans,

Laszlo is new for me, i find it last night and i think that's it is a good way when u have complex interaction on the view part.

I really think that a good integration of Laszlo in a spring would be nice.

It works with XML data so everything is possible.

I'll try to use it with my current spring app next week if someone has any idea, send it and follow me ;-)

Has anyone made any progress here?

I have a spring service serving up an XML view to be consumed by LZX. However, I'd much rather talk directly via Laszlo's <javarpc> remoting.

I don't think this is possible because Laszlo has no idea of our Spring context. Anyone down this road as well?

I also recently came across Laszlo and it seems good.


Did anyone try to use Laszlo + Spring + Hibernate application. If yes, could you please share your experience regarding how to intergrate Laszlo with Spring framework?

Thanks!

I recently deployed a Laszlo view layer with a Spring middle-tier.

I used vanilla Spring MVC that served up XML responses. Laszlo consumed the XML via dataset requests.

The response from the client was phenomenal. RIA rocks!

I'm currently writing a document that I'll post on the Spring, Laszlo, and Liferay sites that demonstrates the usage of Rich Internet Applications via Laszlo with a Spring middle-tier as JSR-168 compliant portlet.

Cheers,

Thanks very much for your prompt response Roll.

I'm looking forward to your article as i'm seriously considering Laszlo for our project.

I'm not a GUI person. So could you please explain a little bit on what do you mean by:

I used vanilla Spring MVC that served up XML responses. Laszlo consumed the XML via dataset requests.

If you could outline those things in a high-level steps, i'll try to do more research on that.

Thanks!

I don't consider myself a GUI person either, which is one reason why I love Laszlo.

I'm assuming you already are familiar with Spring MVC. I have a controller that essentially serves up XML. I currently use XStream for swizzling my model into XML. However, you could inject your model directly into your view and have it create the XML there, use XML-RPC, expose as a web service, etc. There are several possiblities here.

Next, walk through the Laszlo developer documentation. There are several sections on developing "data driven applications". Here you'll learn how to make XML HTTP requests to your Spring middle-tier.

They conceivably could exist in the same webapp, however, I chose for development purposes to have two separate web contexts. One for the Laszlo view and the other for the Spring web application that serves up the XML.

Enjoy!
