Question

我在Netbeans 7.4 / JDK 1.7环境中运行Tomcat 7上的简单应用程序时遇到了问题。

faces-config.xml：

<?xml version='1.0' encoding='UTF-8'?>
<faces-config version="2.2"
    xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd">
    <managed-bean> 
        <managed-bean-name>menedzer</managed-bean-name>
        <managed-bean-class>pl.helion.jeeweb.notowaniagieldowe.entity.Menedzer</managed-bean-class>
        <managed-bean-scope>request</managed-bean-scope>
    <managed-bean>
</faces-config>

pl.helion.jeeweb.notowaniagieldowe.entity.Menedzer：

package pl.helion.jeeweb.notowaniagieldowe.entity;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;

public class Menedzer {
    private List<Spolka> spolki;

    public List<Spolka> getSpolki() {
        return spolki;
    }

    public void setSpolki(List<Spolka> spolki) {
        this.spolki = spolki;
    }

    public Menedzer(){
        spolki = new ArrayList<Spolka>(3);
        Date d = new Date();
        spolki.add(new Spolka("Kocia Spółka Węglowa", "KSW", "energetyczny", 20.0, 11.1, d));
        spolki.add(new Spolka("KitKompDotCom", "KKDC", "informatyczny", 90.0, 3.4, d));
        spolki.add(new Spolka("Kocie Dance Studio", "KDS", "rozrywkowy", 15.0, -11.7, d));
    }

}

这是如何引起的？如何解决？

[编辑]：

几乎逐字节地研究后，我发现了PackMan Error，节点<managed-bean>未关闭，但已打开两次...... BTW。 NetBeans应该显示那种XML解析错误。

Answer 1

标记<managed-bean>未正确关闭
