The Ruby on Rails framework provides some very handy XML features that make it easier to use database data for development and to provide XML-formatted database data for JavaScript applications. JavaScript also has built-in XML parsing capabilities, so it is easy to receive and parse XML-formatted data. But what if you want to access a Java™ application without deploying an additional server? This is JRuby's job. JRuby on Rails is a Java implementatio

Preface Introduction JRuby is an implementation of pure Java based on the famous Ruby programming language, which is a dynamic, open source programming language, characterized by simplicity and high development efficiency. Ruby has good syntax, and programming statements are natural to read and easy to write. This article shows you how to use the NetBeans integrated development environment for JRuby develo

JVM is awesome! Developers people that Bash Java make the mistake of mixing up the Java language and the Java platform. sure, the Java language is verbose; it lacks closures, mixins, etc. but the JVM is freaking awesome. it's blazing fast, it runs everywhere, has multiple garbageCollectors, has native threads and great monitoring tools. as a result, you may still want to run your server-side applications on the JVM. the best part is that you don't have to use the Java language. if you are a fan

I. Overview Rational Function tester is an automated functional testing tool for IBM. It uses Java as a scripting language. If you are not familiar with it, visit the IBM website. Ruby is currently a hot language in Web development. It is simple, flexible, loose, and interesting. In this year's automated testing project, the company used rft to build a testing framework and Ruby to identify some OCX controls on the page.

What is jruby? Jruby is a Ruby interpreter implemented in pure Java. Through jruby, you can directly run Ruby on JVMProgramTo call the Java class library. Many Ruby ides written in Java use jruby to explain the syntax. Jruby, an open-source Ruby interpreter under JVM, can

As a Java programmer, you don't want to use Ruby in your product until you can interact with existing Java applications and class libraries, which support many of the basic features of Ruby. An open source Ruby interpreter under JRUBY,JVM can use Ruby class libraries in Java. Like a standard ruby interpreter, Ruby code can be executed correctly in JRuby, except for invoking native methods (c code) or Java c

The growing sense of JRuby is a promising project, combining Ruby's sexy syntax with Java's extremely rich class library, and the ability of a team to continually fix bugs and improve performance, which has the potential to be a "boy killer". The four recommendations for performance tuning are listed on the JRuby wiki: 1, tuning compiler, JRuby long qiantouming

Recently, organization leaders deployed a task to develop the user self-service system. This task was completed independently by only one of me-Haha, a wonderful job. It happened that the landlord was recently confused by the wonderful features of Ruby, so he put it into the arms of Ruby on Rails without hesitation. However, in the process of system development, the leaders made new instructions to interact with the ruijie Sam system. MB! What should I do? Well, fortunately, there is still

Although JRuby's performance is close to Cruby, sometimes it's still not fast enough. Cruby users can use Ryan Davis's Rubyinline Library, which provides built-in support for C + + to make it easier to generate Ruby's C extensions. Charles Nutter from the JRuby camp has now implemented a Rubyinline builder for JRuby, which can instantly compile embedded Java code. The following is an example of a factorial

I. Overview Rational function Tester is an IBM automated test tool that uses Java as a scripting language and does not understand that his friends can go to the IBM website. Ruby is the hottest language in web development at the moment, simple, flexible, relaxed, and fun. In this year's automated test project, the RFT was used to build the test framework, and the identification of some OCX controls in the page was identified by Ruby.
