JSP not accessing my Beans
yasudevil May 21, 2009 3:52 PMHi I'm really new on the Seam and JSF scenario and it's beeing a preety though but refreshing experience so far.
At the moment i'm trying to make a simple Hello World like application without EJB or JPA.
My configuration files are the following:
faces-config.xml
