jsf-2

问题 I am trying to get the JSF web front-end to redirect to back to the login page (in Spring Security) when the session times-out. I have tried using a meta-refresh approach, however this causes an undesired side-effect that the meta-refresh time will not be updated when only AJAX controls are used on the page. This means that the page may refresh while you are still using it, because you haven't transitioned to another page and only made AJAX calls to the server. I have not found a way to

问题 Is it possible to execute two methods in action of <h:commandButton> ? For example, <h:commandButton action="#{bean.methodOne();bean.methodTwo();}" /> 回答1: You can use f:actionListener like this. <h:commandButton action="#{bean.methodOne();}"> <f:actionListener binding="#{bean.methodTwo();}" /> </h:commandButton> You can add as many f:actionListener elements as you need. 回答2: Add a methodThree in your bean : public Object methodThree() { methodOne(); methodTwo(); return someThing; } And call

问题 The JSF 2.2 web based application I am developing makes use of various error pages which are located in the WEB-INF directory and are displayed when an HTTP error or Java exception is encountered based on the configuration in the web.xml file. On some error pages I would like to include a form which allows the user to report the issue and include various attributes that would be helpful when investigating the issue such as the request URI and the error message. The issue I've got is when the

问题 In my setup I have a @Named Bean, the class ObWithDate is a @Entity with a date field validFrom . Objects of this class are in a List<ObWithDate> of the bean. I want to update the ObWithDate immediately if a user changes a date. The p:dataTable thus is showing several p:calendar components: <h:form id="fUser"> <p:dataTable id="dt" var="i" value="#{myBean.list}"> <p:column> <p:calendar id="cValidFrom" value="#{i.validFrom}"> <p:ajax event="dateSelect" listener="#{myBean.up}" update=":fUser:dt"

问题 Is there a way to decrease the load time of the page in IE just by using Data tables. If we use server side pagination and sorting, can we also do a quick search on server side and also render only that particular tab instead of the whole page. <h:panelGroup id="transactionsPanel"> <h:dataTable> </h:dataTable> <ui:repeat value="#{backing.pages}" var="page" varStatus="current"> <h:commandLink value="#{page}" actionListener="#{backing.page}" rendered="#{page != backing.currentPage}" > <f:ajax

问题 The first thing that I must say is that I never use a web filter on Java Web Applications so perhaps it could be a stupid idea. I'm trying to create a method that could check the privilegies of the user and give the access or not to a certains pages if he can or not access to these pages. For a better explanation I will do an example. You should imagine a crud web application ok? This application have these web pages: List.xhtml (that contains all rows and the links to manage these rows);

问题 I have generating a HtmlCommandButton in backing bean. By clicking that button I want to delete a HtmlColumn from a HtmlDataTable which was also generated in the baking bean. <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/> <title>JSF dynamic</title> </head> <body> <h:form prependId="false"> <br/><br/> <h:outputText value="Enter no. of columns : "/> <h:inputText value="#{MyTest.colNos
