Yes, JRuby is reliable! Oracle uses JRuby for Oracle mix (<a href="http://mix.oracle.com/" rel="nofollow noreferrer">http://mix.oracle.com/</a>), Sun had used it for Kenai (<a href="http://kenai.com" rel="nofollow noreferrer">http://kenai.com</a>), and it's gonna be the next base for java.net (from kenai site: "Work is on-going for migrating the Java.net domain over to the Kenai infrastructure")!!

You can run almost every code, some gems uses native C extension and in JRuby there's a primitive support to it, but yes...rails just works.

You can deploy Rails apps in Application Servers like Tomcat or JBoss with Warbler that wraps Rails apps inside a .war file, it's pretty awesome!

update: you can see a lot of benchmarks here: <a href="http://programmingzen.com/2010/07/19/the-great-ruby-shootout-july-2010/" rel="nofollow noreferrer">http://programmingzen.com/2010/07/19/the-great-ruby-shootout-july-2010/</a>

blocks|key|1956701|text|JRuby岩石！！简单的原因是它的可移植性、特性以及与Java库的集成。我个人使用它与Netbeans和快速调试器，随之而来的似乎非常方便。另外，您不希望看到本机构建错误并处理它们。您为JRuby下载的所有这些宝石都可以在任何平台上100%25地工作。使用JRuby，您只是简单地引入了Java平台独立性的优势。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1956702|此外，JRuby使用本机线程，它使用OS线程，而不是CRuby中的绿线程(我认为最新版本的情况并非如此)|1956703|在吉斯特，加油JRuby！|1956704|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

JRuby rocks!! The simple reason being its portability features and integration with Java libraries. I personally use it with Netbeans and the fast debugger that comes with that seems very handly. Plus you do not want to see that native build errors and handling them. All these gems that you download for JRuby work 100% across any platform. With JRuby, you are simply bringing in the advantages of the Java's Platform independence.

Moreover, JRuby uses native threading which uses OS threads instead of Green threads as in CRuby (i think its not the case with the latest versions though)

In Gist, go JRuby!!

I am doing a lot of jruby work right now and can tell you that rails is certainly a viable option under the jruby interpreter. I've been pretty pleased and in my case have to use many native Java libraries, so jRuby is just such an awesome wrapper around that java code. I will say that I have had some technical challenges some that are worked out, some that are not yet.

<ol>
<li>unit testing: spooling up the jvm and then spooling up rails takes much longer, so your tests take longer to run - solution, potentially something like nailgun that keeps the jvm running</li>
<li>deployment: i have not gotten warbler to work for me, with my flavor of tomcat. this is a major issue for us. </li>
<li>pick your libraries, while some c extensions work, they are not all equally compatible. </li>
</ol>

if you are interested I would highly reccomend the jruby book, in beta, from Pragmantic Programmers at <a href="http://pragprog.com" rel="nofollow noreferrer">http://pragprog.com</a>

blocks|key|1956829|text|对于windows，我发现当处理更多的数据时，它比MRI更稳定。窗口上仍然有一些but，但它们实际上是可以解决的。推荐。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1956830|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

for windows I have found it to be much more stable than MRI when working with larger amounts of data. There are some bugs on windows still but they are actually work-around-able. Recommend.

Disclaimer: I don't use jruby in my day job - I merely experimented with running existing code using jruby.

It doesn't mean that it'll run all code successfully. For example, bioruby currently calls fork on jruby even though <a href="http://github.com/bioruby/bioruby/issues#issue/6" rel="nofollow noreferrer">jruby doesn't really support it</a>. (That's more of a bug in bioruby than a bug in jruby though)

I wouldn't call such behaviour "unreliable" though. It's fail-safe, like a <a href="https://stackoverflow.com/questions/234075/what-is-your-best-programmer-joke/236138#236138">plane that would not get off the ground, much less crash</a>.

I'm interested in promoting JRuby in our office as the platform hosting Rails applications.

But how reliable is it?

Is its performance better than MRI 1.8.7?

JRuby 1.5 states that it is 100% compatible with Ruby 1.8.7, does this mean that JRuby can run any Ruby/Rails code?

How reliable is JRuby?

我有兴趣在我们的办公室里推广JRuby作为Rails应用程序的托管平台。但它有多可靠？其性能是否优于MRI 1.8.7？JRuby 1.5声明它与Ruby1.8.7兼容100%，这是否意味着JRuby可以运行任何 Ruby/Rails代码？
