We are designing a new application with WAF architecture. Since We are new to EJB, J2EE relatd technologies we can't able to write coding for Base classses for Controller servlet, request processor, screen flow manager etc. We have taken WAF architecture coding for Sun blue print. but we couldn't able to find how it actually works. moreover they didn't provide supporting xml files like "mappings.xml" file. Any one can provide a sample small application that implement WAF architecture will really be appreciated.
