No session generation in jsf

阅读更多关于 No session generation in jsf

问题 In JSP, there is an attribute session used for disable autogeneration session in a request. <%@page contentType="text/html" pageEncoding="UTF-8" session="false" %> Is there any way to do same in JSF2? Thanks Why? Because we have a public register form page as a default page in an application. It is a very simple form and session is created everytime people (or robots, etc.) request main page. ManagedBean is RequestScope, but JSF create one session in first navegation request. 回答1: Just don't

Can CDI managed beans and JSF managed beans talk to each other?

阅读更多关于 Can CDI managed beans and JSF managed beans talk to each other?

问题 I have a Tomcat 6 JSF web application that I'd like to set up with CDI beans. I will have to convert the project to CDI gradually though. My question is: can CDI beans and traditional JSF managed beans be injected into each other? Thanks. 回答1: All JSF managed beans (JMB) either are CDI managed beans (CMB) automatically, or can be recognized as such using the beans.xml marker file. (The requirements of a CMB are set very low and basically just dictate the existence of a non-parameter

gzip compression for jsf stuff

阅读更多关于 gzip compression for jsf stuff

问题 I have an jsf application (mojarra 2.1.8, primefaces 3.3) running on tomcat 6. While analyzing the page in firebug with google page-speed, I realized I could optimize some stuff by gzip-compression.

Compressing http://localhost:8080/someApp/javax.faces.resource/jquery/jquery.js.jsf?ln=primefaces could save 72,5KiB (74% reduction). Compressing http://localhost:8080/someApp/javax.faces

JSF Action vs Outcome Attribute

阅读更多关于 JSF Action vs Outcome Attribute

问题 I'm new to JSF and am trying to understand what the difference is between the action vs the outcome attributes? This is not the difference between buttons and command buttons, but between outcome vs action attributes on the same button tag. For instance, I can have: <h:button value="Go" outcome="<value>" /> or <h:button value="Go" action="<value>" /> I'm not sure when to use which one. Also, does it make a difference if <value> is <#{bean.methodThatReturnsStringInNavigationRule}> or <string
