I'm trying to use ajax4jsf 1.1.0 with RAD v7 and WebSphere v6.1.
Then, I tried to deploy a war file incuded in sample:
a4j-simpleRepeator http://labs.jboss.com/portal/jbossajax4jsf/demo/index.html and it work fine.
The diference between first and second test is this line :
filter configuration. So, what is in your web.xml ?
