发送命令输出从JSF managedBean将jQuery终端

我已经集成在与处理命令的一个ManagedBean目的JSF应用程序jQuery Terminal Emulator，而不是在jQuery的。我已经成功地将命令发送给bean，然后将结果设置为回调参数，但我无法弄清楚如何在终端中显示此结果。发送命令输出从JSF managedBean将jQuery终端

下面是相关的代码段：

terminal.xhtml

<h:form> 
     <p:remoteCommand name="sendRemoteCommand" 
      action="#{processCommand.rcAction}" 
      oncomplete="handleComplete(xhr, status, args)" /> 
    </h:form> 
    <h:panelGroup id="term_demo" layout="block" /> 
    <h:outputScript library="primefaces" name="jquery/jquery.js" 
     target="body" /> 
    <h:outputScript library="js" name="jquery.terminal-min.js" /> 
    <h:outputScript target="body"> 
     $(document).ready(function() { 
      $('#term_demo').terminal(function(command, term) { 
       if (command !== '') { 
        try { 
         var result = sendRemoteCommand([ { 
          name : 'command', 
          value : command 
         } ]); 
         if (result !== undefined) { 
          term.echo(new String(result)); 
         } 
        } catch (e) { 
         term.error(new String(e)); 
        } 
       } else { 
        term.echo(''); 
       } 
      }, { 
       greetings : 'Javascript Interpreter', 
       name : 'js_demo', 
       height : 200, 
       prompt : 'js> ' 
      }); 
     }); 

     function handleComplete(xhr, status, args) { 
      // Need to find a way to return args.result 
      // to the terminal! 
     } 
    </h:outputScript>

ProcessCommand.java

@ManagedBean 
@RequestScoped 
public class ProcessCommand { 
private String command; 

public void rcAction() { 
    FacesContext context = FacesContext.getCurrentInstance(); 
    Map map = context.getExternalContext().getRequestParameterMap(); 
    command = (String) map.get("command"); 

    RequestContext requestContext = RequestContext.getCurrentInstance(); 
    requestContext.addCallbackParam("result", command + "_ok"); 
}

在JS功能handleComplete()，可变args.result设置正确到“[command] _ok”，而我' d想要返回它，以便当jQuery终端函数调用sendRemoteCommand标签中指定的Primefaces的<p:remoteCommand>标签时，它能够获得后者返回的结果

非常感谢！

编辑：我使用JSF 2.0（钻嘴鱼科2.2，Glassfish的4，Primefaces 4.0）

我最终改变的策略，并通过一个servlet URI作为第一个参数为terminal函数，该函数，由于GSON，可以处理由终端发送的JSON请求并发送JSON响应。

这是Terminal.xhtml

jQuery(function($) { 
      $('#terminalPanel').terminal("terminalSerlvet", { 
      login: false, 
      greetings: "Javascript Interpreter", 
      tabcompletion: true, 
      completion: function(term, string, callback) { 
       callback(cmd); 
      }}); 
     });

Servlet的方式清洁:)

：

@WebServlet(urlPatterns = "/terminalSerlvet") public class JSONTerminalServlet extends HttpServlet { private static final long serialVersionUID = 1L; protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { System.out.println("Entering JSONTerminalSerlvet#doPost..."); Gson gson = new Gson(); StringBuilder sb = new StringBuilder(); BufferedReader reader = request.getReader(); TerminalCommandData cmdData; try { String line; while ((line = reader.readLine()) != null) { sb.append(line); } cmdData = (TerminalCommandData) gson.fromJson(sb.toString(), TerminalCommandData.class); } finally { reader.close(); } if (cmdData != null) { // Write response data as JSON. response.setContentType("application/json"); response.setCharacterEncoding("UTF-8"); response.getWriter().write(new Gson().toJson(buildJsonResponse(cmdData))); } }
