Question

我有一个JSF应用程序，它有一个表单，当单击该按钮时，它应该重定向到另一个页面。但是在点击按钮后，它会给出一个像http://localhost:8080/LiceningServer/faces/index.xhtml这样的网址，并显示错误。这是我的完整代码。

JSF page

    <h:form class="form-horizontal" action= "index2.xhtml" method="post" id="formId">

               <div>
               <label class="control-label" for="inputEmail">First Name :</label>
               &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
               <h:inputText id="firstname" placeholder="First Name" value="#{form.firstName}"> </h:inputText>
               </div>

               <h:commandButton value="click" action="#{form.submitted}"/>

    </h:form>

managed bean代码

    public String submitted(){  
      return "next.xhtml";
    }

给出错误

Answer 1

删除h：表单上的action和method属性。他们不需要。 JSF负责这一点。

重定向到另一个页面会在JSF中出错
