Auto Generated Code for Using Persistence Not Compiling
I am new to JSF development and was trying to complete the Using Java Persistence in J2EE 1.4 Web Application tutorial. Since I have an existing database, instead of creating a new entity class, I used the create entity class from DB option. I then followed the steps for creating a web interface. When I try to complile the code, I get the following errors. Is there an additional library that I need to include or did I miss a step? Any help would be greatly appreciated.
