Seam 3 is a set of CDI extension. Not a new version of Seam 2 framework actually.
So there are a few ways to create/configure CDI project in JBoss Tools.
1. You can use JBoss Central to create a new Java EE 6 application or any example project which supports EE 6.
2. Create your own maven project with CDI dependencies.
3. Create a new CDI Project using New CDI Project wizard (New->Project->CDI->CDI Project)
4. Create a new Java/Web Project/... and enable CDI support for it (Right click on the project-->Configure->Enable CDI)
Then just add Seam 3 jars into the project's classpath and CDI Tools will enable Seam 3 support automatically.
If you are using maven then adding Seam3 dependencies is enough for that (if you have installed JBoss Tools CDI Maven integration plugins of course)
Thanks for answer Alexey, I'm gonna check the links that you provided me to know how to create CID projects. Just one question more, what IDE do you think that is better for that? JBoss Developer Studio or Eclipse JUNO? Do you have a clear difference between both, advantages or disadvantages of each one?
JBoss Tools is a set of plugins for Eclipse.
JBoss Developer Studio = Eclipse + JBoss Tools
If you didn't work with Eclipse before I would recommend you to install JBoss Developer Tools instead of installing Eclipse + JBoss Tools manually.
And BTW if you still want to use Eclipse Juno + JBoss Tools, be aware that JBoss Tools 3.3.0 supports Eclipse Indigo. You can install it on Eclipse Juno, but we don't guarantee that everything will work.
"JBoss Developer Studio is the supported IDE for doing JBoss Middleware development. It is based on Eclipse and the supported parts of the JBoss Tools project. The IDE comes with everything preconfigured and works out-of-the-box; making it easy to get started doing real work." (c)
btw. Juno has no support for CDI projects except a little support found in Eclipse JSF 2 support for named beans.
JBoss Tools is the only eclipse plugin (known to me) that provides explicit support for CDI.
