Question

我正在为openfire开发一个插件。

从jsp，我使用getter和setter来传输数据。我的问题类似于这里提到的问题： https://community.igniterealtime.org/message/155892#155892

我一直试图从一周内弄明白。

我有以下代码：

<%@ page
   import="org.jivesoftware.openfire.XMPPServer,
           de.meisterfuu.openfire.plugin.teamFantasian_UserServicePlugin,
           org.jivesoftware.util.ParamUtils,
           org.jivesoftware.openfire.container.Plugin,
           org.jivesoftware.util.*,
           java.util.*,
           java.util.HashMap,
           java.util.Map"
   errorPage="error.jsp"%>


<%@ taglib uri="http://java.sun.com/jstl/core_rt" prefix="c"%>
<%@ taglib uri="http://java.sun.com/jstl/fmt_rt" prefix="fmt"%>

<%
    boolean save = request.getParameter("save") != null;    
    String pNameSpace = ParamUtils.getParameter(request, "pNameSpace");
    String pModule = ParamUtils.getParameter(request, "pModule");
    String pCreateUser = ParamUtils.getParameter(request, "pCreateUser");
    String pCreateUser_input = ParamUtils.getParameter(request, "pCreateUser_input");
    String pCreateUser_output = ParamUtils.getParameter(request, "pCreateUser_output");




  teamFantasian_UserServicePlugin plugin = (teamFantasian_UserServicePlugin) XMPPServer.getInstance().getPluginManager().getPlugin("teamFantasian_UserServicePlugin");


    Collection<Plugin> a = XMPPServer.getInstance().getPluginManager().getPlugins();

    out.write(Arrays.toString(a.toArray()));

    if(plugin == null) {

    out.println("Cant find plugin ..!!");
    return;
    }

这是我的目录结构：

请勿使用下划线表示插件名称。将您的插件重命名为teamFantasianUserServicePlugin。

获取实例：

XMPPServer.getInstance().getPluginManager().getPlugin("teamfantasianuserserviceplugin");

插件名称应为小写。
