关于tomcat的WebRTC

我是WebRtc技术的新手，我必须使用我自己的tomcat服务器实现音频/视频和数据交换以进行信号传输。

我已经从github（https://github.com/Mobicents/sip-servlets）分叉了mobicents实现，但是这个庞大的项目工作不正常而且我没有修复/配置它的知识。

我会很高兴看到如何在java中实现服务器端的一些说明，或者可能是一些有用的简短示例。当然，我一直在网上寻找教程，但我没有发现任何可以理解的东西。

修改

目前，我正在尝试运行mobicents demo websockets-sip-servlet。我在浏览器的控制台中获得了一些错误，例如：

* PrivateJainSipClientConnector:processSipRegisterResponse(): SIP registration failed:500  [object Object]
* GET http://localhost:8080/websockets-sip-servlet/Room/undefined 404 (Not Found)
* POST https://api.xirsys.com/getIceServers 400 (Bad Request)

我已从https://mobicents.ci.cloudbees.com/job/MobicentsSipServlets-Release/lastSuccessfulBuild/artifact/下载了tomcat 8版本。

和来自tomcat日志的堆栈跟踪：

它不是一个完整的堆栈跟踪

您能解释一下您想要实现的目标，以便更容易指导您吗？ 首先，下载二进制文件比使用源代码更容易。因此，请尝试使用https://mobicents.ci.cloudbees.com/job/MobicentsSipServlets-Release/lastSuccessfulBuild/artifact/

中较新的版本

Mobicents SIP Servlets和Restcomm使用WebRTComm作为客户端Javascript库。该库允许您使用简单的API来抽象WebRTC的复杂性，并使用SIP Over WebSockets作为交换聊天消息或设置和拆除音频和视频呼叫的信令协议。

默认情况下，RestComm带有一个WebRTC客户端，您可以使用它来自定义以满足您的需求，请参阅http://www.telestax.com/livechat-and-video-call-with-restcomm/，或者您可以下载我们正在处理https://github.com/Mobicents/olympus的新版本并帮助您做出贡献。
