更改.class文件时，是否可以将GAE的dev_appserver设置为自动重新加载上下文?

我正在将Google AppEngine和其内置的网络服务器一起使用.我的开发以一种简单的方式进行:我对.java源代码或.jsp进行了更改，并使用ant进行了编译，并查看了必须重新启动开发服务器的更改.

I'm using Google AppEngine with their built in web server. My development goes about in a simple way: I make changes to my .java sources or .jsp and compile using ant and to see the changes I have to restart the development server.

我想知道是否有办法避免重启开发服务器的最后一步-以某种方式刷新Web服务器的缓存类上下文. Google在此开发服务器上提供的选项非常有限，我想知道是否有更好的方法.

I'm wondering if there's a way I can avoid this last step of restarting my development server - somehow refresh the cached classes context of my web-server. The options provided by Google on this dev server are quite limited and am wondering if there's a better way.

我想避免使用类似我可以购买的JRebel之类的东西，但是对于这个简单的项目，我只是想知道是否可以消除重新启动Web服务器的负担...否则，我将继续使用它.

I would like to avoid using something like JRebel which I could buy, but for this simple project I'm just wondering if I can remove the burden of restarting my web-server... otherwise I'll live with it.
