Question

我努力解决这个问题

我有两个xhtml页面索引页

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"         "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://xmlns.jcp.org/jsf/html"
      xmlns:f="http://xmlns.jcp.org/jsf/core">
    <h:head>
        <title>Facelet Title</title>
    </h:head>
    <h:body>
        <h:link value="Go to page2" outcome="response">
            <f:param name="field1" value="firstvalue" />
            <f:param name="field2" value="secondvalue" />
            <f:param name="field3" value="thirdvalue" />
        </h:link>
    </h:body>
</html>

和回复页

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"     "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://xmlns.jcp.org/jsf/html"
      xmlns:f="http://xmlns.jcp.org/jsf/core">


    <h:head>
        <title>Facelet Title</title>
    </h:head>
    <h:body>
        <f:metadata>
            <f:viewParam name="field1" value="#{bean2.field1}"/>
             <f:viewParam name="field2" value="#{bean2.field2}"/>
             <f:viewParam name="field3" value="#{bean2.field3}"/>
        </f:metadata>

        <h:outputText value="#{bean2.field1}" />
        <h:outputText value="#{bean2.field2}" />
        <h:outputText value="#{bean2.field3}" />
    </h:body>
</html>

并且只有一个bean

  @Named(value = "bean2")
  @SessionScoped
 public class Bean2 implements Serializable{

    private String field1;
    private String field2;
    private String field3;
//...... getters and setters
 }

当我点击索引页面中的链接时，它会导航到响应页面但不设置字段值

你有什么建议为什么不起作用？

注意：我正在使用glassfish 4.0

谢谢...

通过更改名称空格来解决

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:f="http://java.sun.com/jsf/core" 
      xmlns:h="http://java.sun.com/jsf/html">

通过JSF获取请求
