Does Wildfly 18 Supports Seam 2.3 Applications? - jsf

Question

I want to migrate an application from Wildfly 8 to the latest Wildfly 18. The web application uses the following frameworks: hibernate 3, seam 2.2, JSF 1.2, and Richfaces 3.3.3. Since hibernate 3 isn't supported anymore in Wildfly, we need to migrate to hibernate 4 which isn't compatible with Seam 2.2. Thus, we have to migrate to Seam 2.3 and this leads to migrating to JSF 2.3 (Wildfly modules) and to Richfaces 4.
My project is an ear that contains inside it a war folder.
For JSF, I am using the supported module by Wildfly both com.sun.faces.impl and javax.faces.api. I also added jsf-facelets-1.1.15.jar as a jar under web-inf/lib.
For hibernate, I included the following jars in my ear: hibernate-commons-annotations-4.0.5.Final.jar, hibernate-core-4.3.11.Final.jar, and hibernate-entitymanager-4.3.11.Final.jar.
For seam, I included the seam jars: jboss-seam.jar, jboss-seam-debug.jar, ...
For Richfaces, I included the following libraries under the war folder: richfaces-a4j-4.5.17.Final.jar, richfaces-core-4.5.17.Final.jar, and richfaces-rich-4.5.17.Final.jar. I also included their dependencies.
I am still getting this error which I am not able to debug: Unsupported Operation Exception.
Did anyone encountered this issue ? And do you know if Seam 2.3 is still supported by the latest Wildfly especially that on Seam documentation, they gave the project examples on Jboss As 7?
Thank you for your help.

Answer 1

The migration you are trying to achieve will result in a non-supported environment as well.
From http://seamframework.org/
Seam Moving Forward
As many of you may be aware, there have been a number of changes
within Seam over the past year. Here is a quick highlight of the
changes and how they may affect you and your application.
Seam 2
Seam 2.2 targets JBoss AS 5 and 6 as well as JBoss Enterprise
Application Platform 5 - Java EE 5 based architecture Seam 2.3 targets
Java EE 6 capabilities such as JSF2 and JPA2 on the JBoss Enterprise
Application Platform 6 - Seam 2.3 also supports RichFaces 4 which is
also available for commercial support via Web Framework Kit. If you
are looking for the long-term support with a service level agreement
of Seam 2.2 and/or Seam 2.3 then please contact us at
http://www.redhat.com/contact/sales.html Seam 2.3 is part of Web
Framework Kit, included as part of the JBoss Enterprise Application
Platform subscription .
Seam 2.3 was released in September 2012. This is an update to the Seam
2 code base to make it compatible with Jave EE 6. It runs well on
JBoss AS 7.
Seam 3
Active development of Seam 3 has been halted by Red Hat. Many projects
have moved over to Apache DeltaSpike , and others have been absorbed
into different projects. Please see the below table for information
about where the functionality from each module has gone and how you
can participate.
So no, it does not support WildFly 18 (Java EE 8)
Richfaces is 'dead' (sunset) for 4 years now. https://developer.jboss.org/wiki/RichFacesEnd-Of-LifeQuestionsAnswers
JSF 2.x has facelets built-in, so no need to include them. (Causes problems even)
Wildfly 18 has JPA2 built-in so no need to include hibernate manually (Might cause problems even)
Also read https://docs.jboss.org/seam/2.3.0.Final/reference/en-US/html/migration23.html
Switching to using
PrimeFaces (fully html 5, css3 etc compliant)
JPA2
CDI (with Deltaspike)
OmniFaces
OptimusFaces
is a way better thing to do (Although JSF is 'old' compared to e.t.c. Angular it is still modern when combined with the above technologies and more stable).
