Welcome!

Please let us know about your experiences with the Web Beans RI alpha!

Is it a Seam replacement? Can we use it without Seam?

[nickarls]

There is some information on this at the end of the page here

Not exactly - however, Web Beans will form the core of Seam3.

I'm trying to get the gist of it. From your point of view, for a new project would it be suitable to use WebBeans instead of Seam2 ?

Regards.

[gavin.king]

At this moment, probably not, since Web Beans is in alpha, and because most of the features of Seam don't yet exist for the Web Beans environment. Eventually Seam3 (which will be built around Web Beans) will replace Seam2. Somewhere along the path between this alpha release and the GA release of Seam3 (hopefully sooner rather than later), you will be able to start using Web Beans for serious projects.

OTOH, right now is your opportunity to influence the development of the Web Beans standard, so please take the time to try out the RI. We need feedback!

HI Gavin,

I have written introduction article on Web Beans here:
http://www.javabeat.net/articles/98-what-is-web-beans-1.html

I would like to write one example program for my next article on web beans. So, I have downloaded JBoss 5.0. Can I write Web Beans in the 5.0 version. Is there any other things I have to download?

[gavin.king]

Yes, you have to download the Web Beans RI alpha and install it in JBoss. There are instructions in the Web Beans documentation.

HI Gavin,

I have downloaded and installed. But when I am running the example program I am getting the following exception:

10:07:48,954 ERROR [[/Web]] Exception sending context initialized event to listener instance of class org.jboss.webbeans.servlet.WebBeansListener

It says: Check if Web Beans is properly installed into your container

Did you follow all the instructions, and install the Web Beans plugin correctly?

[kks_krishna]

I have followed installing. But I got the error while updating using ant as follows:
