What is a best solution for hot deploy to Jetty?
提问by Vitek
I have a web application which is running on jetty. Continues builds are built on hudson. I would like to make a hot deploy on demand from hudson.
我有一个在码头上运行的网络应用程序。继续构建建立在 hudson 上。我想根据 hudson 的需求进行热部署。
I found cargo plugin which should be able to do so but cargo's web doesn't show any complete example how to do it - for remote jetty server - may be I miss it?
我发现货物插件应该能够做到这一点，但货物的网站没有显示任何完整的示例 - 对于远程码头服务器 - 我可能会错过它吗？
What do you suggest? Do you have any other better solution?
你有什么建议？你有其他更好的解决方案吗？
thank you,

Jetty : can be run as as standalone : just remote copy the war you build . Standalone Jetty instances can be run independent ports .
Jetty：可以作为独立运行：只需远程复制您构建的War。独立的 Jetty 实例可以运行独立的端口。

For those of you using Windows, if you run into file locking errors, visit:
对于使用 Windows 的用户，如果遇到文件锁定错误，请访问：
http://docs.codehaus.org/display/JETTY/Files+locked+on+Windows
http://docs.codehaus.org/display/JETTY/Files+locked+on+Windows
Windows locks the files Jetty loads into memory. The above link will show you how to prevent that.
Windows 会锁定 Jetty 加载到内存中的文件。上面的链接将向您展示如何防止这种情况发生。
