In addition to building Web and console applications with Ruby, you can write complex GUI desktop applications that run unmodified on multiple platforms. Thanks to JRuby, a robust alternative to the traditional C implementation of Ruby, Ruby GUI toolkits can use UI tools available to the Java platform. This article introduces Monkeybars, a library that uses JRuby and Swing for building applications, and takes you through an example application. ...

Andreas blogged about why he likes JRuby even though he dislikes Java. JRuby is "It's just Ruby" with more than 50,000 tests to ensure MRI compliance. The blog highlights that there is no need to know Java, at all, to run JRuby. Here are some advantages that are described in the blog: JVM runtime optimization Efficient memory usage Native threads to spread work on multiple cores Great garbage collection to make memory usage more efficient JIT and AOT compilation Inegration with Java libraries Running Rails applications on existing Java application servers Documentation and specs Read more details here . Do you know Rails applications can be deployed (without any packaging) on GlassFish v3 ? Check out more details here . Technorati: lotd JRuby ruby rubyonrails glassfish ...

Among my friends, it's not a secret that I personally don't like Java. During my time at the university, I had to deal with it for some courses, but somehow nobody could convince me to really like the language. With Ruby, it was the exact opposite - I saw a few code examples, read some articles about it and I immediately started to like the language and it's charming way of doing OO like I always wanted it to be. ...

Had an interesting bug using Hibernate from JRuby today. Totally unexpected actually. Interestingly, it actually exposed a problem with dynamic dispatch when going into a static language. To a degree I guess it’s about getting our overload resolution more correct, but it seems like a general rule will be hard. ...

This is an interesting thing I ran across when dealing with JRuby 1.1.4 and Swing - some of this may be just my lack of understanding of some of the Java integration features, some of it may be lingering bugs in the Java integration, and some of it may just be what has to be done to make it work; anyway - here goes. ...

The JRuby project is making Ruby faster and more scalable than ever. One advantage to running Rails on the Java Virtual Machine is that you can leverage other Java libraries, like the Apache Derby database. The blend of Derby, JRuby, and Rails allows for rapid prototyping of dynamic Web applications. Learn how to use these technologies together to prototype your next great idea. ...

I started out building Roodi using the JRuby apis to parse Ruby code and build an AST. My main alternative to that was to use ParseTree. The advantage of using JRuby was twofold. Firstly - I could get access to newline characters as part of the AST, which I wanted to use in checks. Secondly - I could get access to line numbers, which I wanted to use as part of the error message output. I've just sacrificed both of those advantages and switched the code base to use ParseTree instead. Why? Because it makes the tool more widely usable. I had my own non-JRuby projects that I was trying to run Roodi in, and it became a pain in the ass. Now I get much better portability, which is worth the sacrifices I had to make. I suspect I can patch line numbers in later, and I'm not that fussed about losing the checks that needed to check the newline characters. ...

A compilation of today's news of interest: Jacob explains the (simple) configuration options for JRuby Pool . SSS does a Shallow Dive into Mural , the Open Source MDM engine in the GlassFish community. The JSR314 EG has released the Expert Draft 2 for JSF 2.0 ( Download ). This version includes Section 13.3 on JavaScript API (thanks for the tip , Roger), as well as Section 3.6 on Composite UI Components (see the Enterprise Tips on this feature: Part I and Part II ). Our household owns several aging Apple laptops so I am keeping an eye on the MacBook Shipments rumor, although OpenSolaris continues to make progress and that may soon be a realistic option for us. Intel has announced the new high-end Dunnington processors ( InternetNews ), and Sun already has machines to accompany them ( Marketwatch ). And in all the noise about the LHC I had missed that the CERN is Thumpers and StorageTek products to store the data - through the Customer Ready program. ...
