Note: Under WEB-INF : componet.xml, pages.xml and web.xml are there.
pages.jpdl.xml is outside the WEB-INF i.e. where seam.properties is put.
Problem: When we click the <h:commandButton value="Guess" action="guess"/>
on numberGuess.jsp, the navigation to the next page is not happening.
We are using seam.2.0.0 and jboss server is 4.2.2.GA. -
