我对 PrimeFaces 手机非常陌生。我正在使用 PrimePush 技术开发一个移动聊天示例应用程序。

我在用

  • primefaces-3.4.2.jar
  • 大气兼容-jbossweb-1.0.8.jar
  • 大气兼容tomcat-1.0.8.jar
  • 大气兼容-tomcat7-1.0.8.jar
  • 大气运行时-1.0.8.jar

我能够在 PrimeFaces 的桌面版本中运行 PrimePush 聊天。它运行良好，但如果我对移动版本使用相同的示例，JBoss 6.1.0 会出现以下异常：

java.lang.NullPointerException

我的 Facelets 页面是：

                            //keep scroll

                </pm:content>

            </pm:view>

        </pm:page>

    </f:view>

</html>

我的支持bean是：

   package test;


    import java.util.ArrayList;
    import java.util.List;
    import javax.annotation.PostConstruct;

    public class ChatUsers {

    private List<String> users;

    @PostConstruct
    public void init() {
        this.users = new ArrayList<String>();
    }



    public List<String> getUsers() {
        return users;
    }

    public void setUsers(List<String> users) {
        this.users = users;
    }

    public void addUser(String user) {
        this.users.add(user);
    }

    public void removeUser(String user) {
        this.users.remove(user);
    }

    public boolean contains(String user) {
        return this.users.contains(user);
    }
}
