Greetings ... Pete and Fmars, thanks for your answers. I obtained successfully deploy a project with Seam 1.2.1 and Trinidad 1.0.1 on JBoss AS 4.2.0, with the normal Jars required and I put adf-facelets.jar in the WEB-INF/lib ... I needed this jar to works my project. I have a only question, this Jar is free for use or is a propietary library, because I don't see this Jar in the MyFaces / Trinidad distribution ?. Thanks !!.
