问题 I noticed that there are different bean scopes like: @RequestScoped @ViewScoped @FlowScoped @SessionScoped @ApplicationScoped What is the purpose of each? How do I choose a proper scope for my bean? 回答1: Introduction It represents the scope (the lifetime) of the bean.

Are you by the way already aware of the new JSF 2.0 "implicit navigation" feature? 回答2: You need to use wildcards to achieve this Just

问题 I'm migrating a jsf 2.0 application to jsf 2.2.6. There is a extensive use of implicit EL object component as styleClass="#{component.valid?'':'err'}".

问题 I want to use JPA/JNDI, as my experience with Netbeans and Glassfish has been that I could configure database settings at the server and so I'd be able to publish to different servers without changing anything in the code or configuration.
