But I have already this line in my components.xml. As you can see this exception rised during instantiating of the session bean Dispatcher. May be I can instantiate by that line: <core:dispatcher name="Dispatcher"/> ? It seams, that I know where the problem. I have seams jars in /lib and /deploy/jbossweb-tomcat5.5/jsf-libs/ directories. Am I correct that this error may occure due to imposibility in instantiate SessionLess library from that directories?
