If you are building a Rails application, JRuby on Glassfish is a winning combination. I have five Rails apps deployed to Glassfish and I haven't had any problems so far. I have been impressed with the performance and deployment was super easy.
Lots of activity in the Java world. I talk to many customers deploying new projects in Java. I also see lots of activity in JRuby and other dynamic languages. Take a look at the Tiobe Index for a more : http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html
As for Metro, on GlassFish, you can call Java libraries from dynamic languages (and vice-versa), so Project Metro with Java, JRuby, etc, is an option.
我认为你的观察很有偏见。 最主要的是需要。 你是否需要通用数组来做所有事情，或者你可以在没有通用数组帮助的情况下有效地完成所有事情...:)并且Java并没有过时..它实际上是一个巨人。 v. 大巨人。 这取决于您的项目，您将如何管理它以及您将运行哪些服务，正如您自己所说的 ROR 一样。 尝试一下 Java，你一定会生活在其中:)
your observation is quite biased i think. the main thing is need. do you require generic arrays for everything or you can do all the thing efficiently without the help of generic arrays ... :) and Java is not outdated .. it is actually a GIANT . a v. big GIANT . it depends on your project how you are going to do it manage it and what services you are going to run as you yourself said abt the ROR . give a shot on Java you will surely live in it :)
I would guess that both suggestions fit your needs equally good. So when you are more familiar with the .NET tools and libraries you should stick to that since there is not much value in learning two things that do (about) the same. Specially when those things are as complex.

如果您正在构建 Rails 应用程序，JRuby on Glassfish 是一个成功的组合。 我有五个 Rails 应用程序部署到 Glassfish，到目前为止还没有遇到任何问题。 其性能给我留下了深刻的印象，而且部署非常简单。

Java 世界中有很多活动。 我与许多使用 Java 部署新项目的客户交谈过。 我还看到 JRuby 和其他动态语言中的大量活动。 查看 Tiobe 指数了解更多信息：

至于 Metro，在 GlassFish 上，您可以从动态语言调用 Java 库（反之亦然），因此使用 Java、JRuby 等的 Project Metro 是一种选择。

我猜这两个建议同样适合您的需求。 因此，当您更熟悉 .NET 工具和库时，您应该坚持下去，因为学习两个功能相同的东西没有太大价值。 特别是当这些事情如此复杂时。
