facescontext

问题 I am trying to add some unit tests to a JSF application. This application didnt rely heavily on any best practices, so many service methods use the FacesContext to pull data from managed session beans like so: (this is inside a util class) public static Object getPageBean(String beanReference) { FacesContext fc = FacesContext.getCurrentInstance(); VariableResolver vr = fc.getApplication().getVariableResolver(); return vr.resolveVariable(fc, beanReference); } What would be the best way to mock

问题 I've been struggling for the last couple of days with the login part of my web app. I've gotten to the point where I can succesfully authenticate a user using the JDBCRealm on tomcat(by reading users from a sql server database). Now I want to send some kind of feedback when the user's account has been blocked, or when the credentials are incorrect, this is where I'm stuck now. I wanted to use this: try { request.login(request.getParameter("user"), request.getParameter("pass")); } catch

问题 The problem is the following: I need to serialize the user session, so, it will still be present after a server restarts. Using JavaEE and Tomcat 7 works fine with implements Serializable , but the problem is the FacesContext . Indeed, after restarting the server, FacesContext.getCurrentInstance() returns null , and therefore I cannot access the message bundle (and therefore my message.properties cannot be found anymore). So, how do I keep the FacesContext when restarting Tomcat? 回答1: Your

问题 I use PrimeFaces 3.5.x and Mojarra JSF 2.1.x I would like to access and show the versions of both libraries programmatically. I use the versions as maven2 properties, but I hope there is an easier way to get the versions. I hope to find something like: Primeface.getVersion(); FacesContext.getCurrentInstance(); A JavaScript based solution would be fine too, since I only want to display the version on a status page. 回答1: For JSF: //returns the major version (2.1) FacesContext.class.getPackage()

问题 After autheticating my user, I want to put a reference in the session to current logged in user. Here how I do it in the setCurrentUser method : FacesContext facesContext = FacesContext.getCurrentInstance(); HttpSession session = (HttpSession) facesContext.getExternalContext().getSession(true); session.setAttribute("CURRENT_USER", currentUser); Unfortunately, the session reference is always null ! Alternatively, I tried with the sessionMap FacesContext facesContext = FacesContext

问题 I have an ADF web application with Faces 1.2 In my managed bean I am trying to access the parameters of the post request, but always getting null. This is my post form that I am posting to the Faces: <form name="input" action="http://127.0.01:7072/myapplication/faces/login.jspx" method="post"> <input type="hidden" name="user" id="user" value="myUserName"/> <input type="submit" value="Submit"/> </form> FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("user");

问题 I've been trying to use JSF 2.3 with TomEE server and I'm having problems using the @Inject annotation with the FacesContext object. When I use it, i get the following exception while starting my TomEE server: SEVERE: CDI Beans module deployment failed org.apache.webbeans.exception.WebBeansDeploymentException: javax.enterprise.inject.UnsatisfiedResolutionException: Api type [javax.faces.context.FacesContext] is not found with the qualifiers Qualifiers: [@javax.enterprise.inject.Default()] Am

问题 I have a stateless bean which has a method, where I want to get the current/logged user. My code to get it: Principal p1 = FacesContext.getCurrentInstance().getExternalContext().getUserPrincipal(); But I am getting nullpointer exception on this. Why is that? Or is there any other way to get the logged user? I am using weblogic. 回答1: You're not supposed to grab the FacesContext in an EJB. Even more, your EJBs should be completely free from any JSF dependencies. In other words, you should not

问题 I was wondering what is the correct way of implementing the custom Validator in JSF 1.2. In my Validator class' public void validate(FacesContext context, UIComponent component,Object value) throws ValidatorException {} method, I am doing the validation check and just adding the FacesMessage instance to the context by context.addMessage(new FacesMessage(xxx...); in case of invalid condition. This seems to be working fine in my application. However, I am not sure if I also need to explicitely
