jsf-2.2

问题 Is this a correct approach to inject @ApplicationScoped bean in @SessionScoped bean? will this lead my application scoped bean to be stored in the session of every user? I have an application scoped bean that contains some values we share among all the system users, and now I need to get that values within a method in a session bean. 回答1: Injecting a bean of the same or a broader scope in another bean is completely legal and correct either in JSF or CDI beans, like the example you provided.

问题 Caution : Although this question covers long textual information with a mess of Java code snippets, it is merely targeted to JavaScript/jQuery and a bit of PrimeFaces stuff (just <p:remoteCommand>) as mentioned in the introductory part in the beginning.

问题 My first JSF page was throwing javax.faces.application.ViewExpiredException . while I searched I got this solution which solved my problem. <context-param> <param-name>javax.faces.STATE_SAVING_METHOD</param-name> <param-value>client</param-value> </context-param> But I am concerned about the security implication. 回答1: This doesn't save the "session" in client side at all.

If I have JSF tags in my dynamic XHTML content like

问题 So I have this very weird issue... I have tried searching all over StackOverflow and tried everything I could find, but I simply cannot fix this error from happening. The error is: /index.xhtml @15,60 value="#{user.name}": Target Unreachable, identifier 'user' resolved to null It's a school project and the project works for some of my classmates, but it also won't work for some.
