...two excerpts from ReadMe.txt and UsingICEfacesWithSeam.html included with the demo:
Note: As of the ICEfaces 1.6.0 DR#2 release ICEfaces has been tested to work with Seam v1.1.6. Due to Seam API changes introduced in Seam 1.2 that break backwards-compatibility support for Seam 1.2 is not available in this release, but will be provided in subsequent releases.
(but the Seam 1.1.6 runtime libs are included in the demo EAR, so no sweat for the demo), and:
The source code for the application is located in the seam-comp-showcase.jar (inside the seam-comp-showcase.ear)
Also note that the EAR is built using JDK 6, so when running into "java.lang.UnsupportedClassVersionError: Bad version number in .class file" you'll need to run JBoss using a newer JDK.
Cool, good news :-)
The slighly bad news is that it's not reccomneded yet to run on 1.2 as something chnaged in Seam for the 1.2 fix.
They hope to have this fixed for the 1.6 Final (due ???)
