Hi people! I'm new on the GWT 'world' and i'm making my final project of my graduation.
On this project I need use persistence and my problems begin here... I'm trying to call a RPC but it return an error on create the Entity Manage Factory :( This is the first warning: > Starting Jetty on port 0 > [WARN] Could not instantiate listener > com.sun.faces.config.ConfigureListener: java.lang.ClassNotFoundException: > com.sun.faces.config.ConfigureListener And this is the error when i try use RPC(with GWT application running):
