Jboss does not load SeamResourceServlet

[designeng]

I'm newbie in Seam, and I need your help. Project can not be deployed for this reason:

DEPLOYMENTS IN ERROR:
  Deployment "vfs:///C:/Users/1/indigo/.metadata/.plugins/org.jboss.ide.eclipse.as.core/JBoss_6.x_Runtime_Server1351075074523/deploy/MyProject.war" is in error due to the following reason(s):
 java.lang.ClassNotFoundException: org.jboss.seam.servlet.SeamResourceServlet 
from BaseClassLoader@19134a{vfs:///C:/Users/1/indigo/.metadata/.plugins/org.jboss.ide.eclipse.as.core/JBoss_6.x_Runtime_Server1351075074523/deploy/MyProject.war}

Though as it's said in the guide-reference, SeamResourceServlet is the Seam built-in feature.

jboss-seam.jar I added to the project build-path.

Something missed?

Configuration:

java 6

jboss 6.1.0 final

seam 2.2.2

eclipse Indigo

jboss tools 3.3.M3

Please, help! The project should be started in a short time, and this annoying error prevents work.

Sorry, it seems to me I guess what's wrong. I tried to build project from source in workspace, and added seam jars not entirely, "on demand" by compilation problems. Whereas the classic seam project created by seam-gen (Eclipse "Seam Web Project" tab) loads all them in Web App Libraries. So all I need is to create seam project from scratch  by jboss-tools and put existing source in it, flood over, so say, no idea how it should sound in english. Yes?
