jsf-2

问题 I'm having a project using JSF2 (2.1.2), Richfaces4 (4.0.0.Final) on tomcat6 (6.0.28). In order to manage portability between Tomcat and WebSphere7 for my EARs, I have the following jars inside my tomcat lib: el-api-2.2.jar, jsf-api-2.1.2.jar, jsf-impl-2.1.2.jar, validation-api-1.0.0.GA.jar. My problem is that I never managed to change the log levels of JSF or Richfaces and except from the initialization ones, I don't see any inside my console. Even when I get exceptions in my server response

问题 I have a JSF 1.2 based webapp from which I copied the JSTL import xmlns:c="http://java.sun.com/jstl/core" You can also find this import in many places on the Internet. I can't remember whether the above worked in my former web project or not, in any case, it does not work in my current JSF 2.0 based webapp. I got a warning from the container saying: Warning: This page calls for XML namespace http://java.sun.com/jstl/core declared with prefix c but no taglibrary exists for that namespace. I

问题 I've a little problem right there. When I want to populate DataTable in JSF I have to create a model first, then use it in my view. Like on Primefaces sample here. And now, I have to create DataTable that will display data, that came from webservice. I don't know how many columns there will be, and I don't know their names... Could you recommend some wise solution ? PS. I don't know also how to returned data from webservice - it is still to determine. EDIT public Bean() { columns = new

问题 Im working on a web application using JSF2 . I want to pass parameters from a managed bean in backing bean action and I want to retrive the same parametrs in an other managed bean the both with a request scope. Thanks in advance. 回答1: Use <f:param> in the command link/button and use @ManagedProperty or <f:viewParam> in the target bean or view.

问题 I do not understand the behaviour of JSF2 during valdation. Hope someone can help me. I have a form where the fields are validated after (ajax) submit - ok If the validation failed a error message is shown - ok For my example when I enter a valid birthday and the field name is empty an errormessage for name is shown after submit. Now when I enter a valid name and delete the input from the birthday field an errormessage is show for birthday (that's ok) but now the old 'valid' birthday stands

问题 Is bookmarkability achievable though using the includeViewParams=true query parameter with JSF implicit navigation ? If yes, then how ? 回答1: First we need to understand what exactly "bookmarkability" is and what exactly includeViewParams does. This way the effect of the combination of both can be better understood. Bookmarkability concerns the HTTP request URL in its exact form as you see in the browser's address bar. It's exactly the URL as the enduser would store in its bookmarks and/or

问题 JSF 2.0, Mojarra 2.0.1, PrimeFaces 3.4.1 There are similar questions but I need sth. else; javascript function has to wait for the backing bean method, which is filling the variable that wanted to be pulled from js function. What I want to say is: <p:commandLink action="#{statusBean.getStatuses}" oncomplete="afterLoad()"/> Assuming js function just getting the value and printing it to the screen. function afterLoad() { alert("#{statusBean.size}"); } And here is the birthday kid: @ManagedBean

问题 Is there any scope like JSF @ViewScoped in Spring 3.0? I have an application using JSF+Spring where backing beans are managed by Spring. I didn't find any scope like JSF wiew scope in Spring. I saw the blog Porting JSF 2.0’s ViewScope to Spring 3.0, but it didn't work for me. Here's my attempt on the custom Spring scope: import java.util.Map; import javax.faces.context.FacesContext; import org.springframework.beans.factory.ObjectFactory; import org.springframework.beans.factory.config.Scope;
