Seam 1.2.1.GA examples are targeted at JBoss AS 4.0.5.GA. You'd need to make some modifications to them to get them running on JBoss AS 4.2.0.GA
On jboss-4.2.0 I had present this changes that I had to consider for running jboss seam 1.2.1 with support of MyFaces 1.1.5, but as soon as I deploy the same example on jboss-4.0.5 with EJB3 support, the server shows me the same error code.
Hi, Pete, accept my apologies, because I again setup my version of jboss-4.0.5-GA and it works successfully. Where can I found documentation about the process that I have to do, for the compatibility with jboss-4.2.x-GA and jboss-seam-1.2.1 ?. Thx, for your help.
Follow the last 3 bullets here: http://docs.jboss.com/seam/1.2.1.GA/reference/en/html_single/#d0e2067
You may also need commons-beanutils and commons-digester as they are no longer in the jsf-libs, just include those in your project lib folder and build script for the war.
Thanks, Samuel for your help.
