You will probably need to extract the remoting helloworld example again, as it got some Seam-1.2.1 files copied in to it. They changed some of the package names for remoting between Seam 1.2.1 GA and Seam 2.0 BETA. I uploaded a new file that excludes the Seam classes. Grab the file from http://wiki.jboss.org/wiki/attach?page=JBossSeam%2FFlexSeamExampleHelloWo... and extract the files to the SEAM_HOME/examples/remoting/helloworld/view dir. Rebuild with ant and deploy. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4066793#...
