I am trying to run this example in AS 5. I have modified the build to use the env vars. and I have changed the persistence.xml to include the schema. I can build and deploy the ear. I am getting an error from running the application. I get a first screen with create new todo and Show all todos but if I click on any link I get an error page: Bean or property class TodoBean for managed bean todoBean cannot be found. AS I am a complete beginner, can some one suggest what I can do or what is wrong? I have a strange feeling that the server is confused with so many deploy and undeploys but I don't know how to reset it.
