jsf-2

问题 I'm using: -primefaces 4.0 -jsf mojarra 2.2 -google app engine (servlet api 2.5) and this solution (Getting primefaces p:fileUpload to work under google appengine) doesn't help me because my version of primefaces is higher. There is exception when I'm using my form below with p:commandButton: java.lang.NoSuchMethodError: javax.servlet.http.HttpServletRequest.getPart(Ljava/lang/String;)Ljavax/servlet/http/Part; at org.primefaces.component.fileupload.NativeFileUploadDecoder.decodeAdvanced

问题 I am trying to understand why my login form does not display the validation message that says "wrong email or password" when the password is entered wrong.

问题 I've read that it is possible to get primefaces fileUpload to work with google appengine with a bit of tweaking. It requires apache fileupload and common io, so I added commons-fileupload-1.2.2.jar and commons-io-1.3.2.jar to my WEB-INF/lib folder. Then following the instructions of primefaces, I added their servlet: <filter> <filter-name>PrimeFaces FileUpload Filter</filter-name> <filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class> <init-param> <param-name>thresholdSize

问题 I am working with the application, which has JSF2 framework. The idea of that framework is to manage connection between Backend (Java) and Frontend.

And so, as I am building Frontend architecture based on modules pattern which has private scope each. Inside several modules I need to make AJAX call to get some data from Backend, but if I am using standart

问题 Is it possible to integrate Spring Security 3 and JSF 2, keeping JSF working as default, instead of show the new url when the user navigates, keep the old url, without using the redirect JSF attribute to navigate through pages? I can't found documentation about this. All articles I found the author redirect the page when navigate. Thanks 回答1: By default the FilterSecurityInterceptor will only execute once-per-request and doesn't do security re-checking unless there is change in the url but

问题 I know that by replacing the el-api.jar in the lib folder of the Tomcat 6 directory with an EL 2.2 capable version that it is possible to utilize the power of EL 2.2 in Tomcat 6.

问题 i define h:messages component as follows: <h:messages id="summary" styleClass="summary" globalOnly="true"/> but when i inspected element with firebug, i noticed that the id is translated to something like: j_idt33:summary what's that prefix, and why it's generated ? 回答1: That's the ID of the parent NamingContainer component like <h:form> , <h:dataTable> , <ui:repeat> , <f:subview> , a composite component, etc. JSF prepends the generated HTML client ID with the ID of the parent namingcontainer

When I add the actionListener to the menuItem I am getting an java.lang.InstantiationException. @ManagedBean(name = "sampleBean") @ViewScoped public class Sample1 implements Serializable { private MenuModel model; public Sample1() { model = new DefaultMenuModel(); for(int i = 0; i < 3; i++){ MenuItem item1 = new MenuItem(); item1.setValue("test1" + i); item1.setAjax(false); item1.setId("item1

问题 I am developing a JSF 2.0 application. On click of , I perform some logic in the backend bean action, need to redirect to another URL in a new window, and perform some clean up work in my original bean action before exiting the action. I am currently using externalContext.redirect() method along with "faces-redirect=true" (since I have some clean up code to be executed after the redirect happens). But the external URL is being opened in the same window. I would require it to open in a

问题 I am writing one composite component like a complex inputtext, that requiere a complete form (it will show a search form and one list of results for the user selects one of them). <composite:implementation> <div id="#{cc.clientId}" class="#{cc.attrs.styleClass}"> <h:inputText id="txtIdentificador" ...> <h:graphicImage id="imgIdentificador" ...> <h:inputText id="txtDescripcion" ...> <h:form id="formF2ItemWidget"> ... </h:form> </div> </composite:implementation> Logically, I would like to use
