I have existing JSF portlet application running in Liferay ,How to add Seam support? I am using JSF2. Also I am confused which seam version should I use? Seam2 or Seam3?
Thanks,
Manoj
I've not added Seam support to an existing JSF application, so I can't comment on that part. If you are using JSF2, though, your only option at this point is Seam 3. Support for JSF2 is slated for Seam 2.3, but that is in Beta right now. Here's the latest info I've seen on Seam 2.3: https://community.jboss.org/blogs/marek-novotny/2012/04/02/seam-230beta1-is-out

I'm trying to move our application from an old JSF 2.2 version to JSF 3.0 (part of the Jakarta EE 9 platform). In the transition we want to replace the Mojarra implementation of JSF and want to replace it with the standard jakarta.faces-api. In the past we used explicit implementaions of JSF, servlet and other technologies, part of the Java EE specification. Now we want to use the standard-api approach.
I have a problem with a class that don't exist in the standard api but in the Mojarra implementation of JSF, the AbstractTagLibrary.
We use a Websphere-Liberty in the newest version, so with activated JSF features the application useses MyFaces.
What i tried so far was to replace the AbractTagLibrary with an own implementation. Bot i got an error that AbractTagLibrary should be of type org.apache.myfaces.view.facelets.tag.AbractTagLibrary.
The AbractTagLibrary is used to create custom EL functions. Like in this article.
My question is, how can i replace the AbstractTagLibrary with the standard jsf-api approach? Is there a good way to approach such a problem?
As BalusC said in his comment, the approach is JSF 1.x minded and can be solved by a JSF 2.0 approach explained here: https://stackoverflow.com/a/7080174.
Last week IceFaces has released its new version 2.0.0. It was long been in the beta version and finally came out to final version. In the release notes it is specified as "JSPs are not supported by ICEfaces 2.0 - use Facelets". What does that mean?. Are we not suppose to write any JSP's?. What about the existing projects running on JSP files.
Please advise me.
It's not that IceFaces specifically doesn't support JSPs. It's the fact that IceFaces 2.0.0 is based on JSF 2.0 and it takes advantage of a couple of JSF 2.0 specific features.
A lot of the new JSF 2.0 specific features are simply not supported in JSP. So if any technology depends on those features, it automatically doesn't support JSP. (this is one reason why it's so important for legacy JSF projects to migrate from JSP to Facelets ASAP).
I put some references to authoritative sources on the wikepedia article about Facelets (http://en.wikipedia.org/wiki/Facelets). This is the one from the official specification (emphasis mine).
JSF 2.0 (JSR 314, http://jcp.org/en/jsr/detail?id=314) specification, maintenance release 2, section 10.1:
Facelets is a replacement for JSP that was designed from the outset with JSF in mind. New features introduced in version 2 and later are only exposed to page authors using Facelets. JSP is retained for backwards compatibility.
From JSF 2.0, Facelets is the official view technology. Even if JSP is supported it will be minimal. Read more here
How can I configure jsf in openbravo? Is it possible?
If possible, could you guide me, since I am new to openbravo.
jBoss Seam integrates with Openbravo. Seam itself was brought to make easier integration of JSF with another technologies.
I have been looking for a JSF extension (Richfaces, IceFaces, and more) but all seem to be according to JSF1.x and ones for JSF2.0 are still alpha or in development and most of the documentation assumes you're using JSF1.2.
Is there any production well known extension available?
RichFaces 3.3.3 is compatible with JSF 2.0. It has however no full JSF 2.0 integration yet.
PrimeFaces 2.0 is already JSF 2.0 ready for months, it was the first to do so.
My opinion would be biased if I say PrimeFaces I guess :) So for real life experiences please see: http://www.primefaces.org/whyprimefaces.html
Is there any good java cms compatible with jsf seam ?

Nuxeo. I haven't used it, but it's been around for a while.
