Hello,
I starting to make a simple application using Tapestry 3.1 I have tomcat 5.5.7
using JDK 1.5.
My next step was to integrate a call to hibernate but this part is not working
yet.
Going to this url: http://localhost:8080//firstApp/app?service=page/Login
I am getting this error: org.apache.tapestry.ApplicationRuntimeException
