JetBrains Releases IntelliJ IDEA 5.1 Java IDE

Upgrade provides unprecedented localization support for Java applications, enhanced JavaScript and plug-in development support, and much more

February 06, 2006

Prague, Czech Republic, February 6, 2006 — JetBrains, creators of intelligent, productivity-enhancing applications, today announced the release of IntelliJ IDEA 5.1, the latest version of the company’s award-winning Java IDE (integrated development environment). IntelliJ IDEA 5.1 is a professional-grade tool for developers working in situations where time is money and sustained productivity is a measure of success.

Perhaps the most significant new functionality in Version 5.1 is an unprecedented level of support for internationalization of new and existing Java applications. The main new features and enhancements in IntelliJ IDEA 5.1 include:

  • Industry’s best i18n support
    IntelliJ IDEA’s greatly enhanced internationalization support now surpasses any other Java localization tool currently available, with capabilities that include:
    • New Quick Fixes for the Hard-coded string literal inspection, including the ability to smartly internationalize a string concatenation that contains hard coded literal values.
    • Convenient, sophisticated means to exclude particular string literals from internationalizations. Among these, the @NonNls annotation can be applied to constants, parameters, even entire methods, etc. causing them to be ignored for localization.
    • New intention actions and inspections for formatting properties and messages that allow you keep application resources in a consistent state.
    JetBrains has created a Japanese localization of IntelliJ IDEA 5.1 using the new i18n functionality. The localization is being released concurrently with the original English version through XLsoft K.K. – the JetBrains reseller in Japan. Information (in Japanese) is available at
  • Improved JavaScript and Web Development support
    Version 5.1 introduces a number of important improvements to JavaScript support, equipping both experienced developers and “newbies” with a full arsenal of features. Even AJAX development becomes quick and simple (especially when developing AJAX libraries).
    Other new enhancements include new navigation, completions and refactorings, plus new Find Usages capabilities for JavaScript and (X)HTML.
  • New JSP debugging support
    Source-level JSP debugging when remotely connected to IBM WebSphere 5.1 or later. Other enhancements to JSP/JEEE support include completion and/or renaming of references to Java methods from Hibernate, Spring, and JSF configuration files.
  • More support for plug-in developers
    New actions for auto-creating new application, module, and project components make it easier than ever to begin creating custom plug-ins. New inspections validate the consistency of plug-in descriptors.

Also included in this release are additional inspections plus numerous smaller-scale improvements. Details about new features and enhancements are available online at the JetBrains web site at:

“Millions of Java applications now out there do not, or cannot, realize their full potential in today’s global marketplace because a single human language was ‘hard-coded’ into them,” said Alex Tkachman, JetBrains Director of Marketing. “Until now, it simply has been too difficult and expensive to localize many of these applications. JetBrains IntelliJ IDEA 5.1 provides a technologically sophisticated, cost-effective and business-efficient means to open new horizons and marketing opportunities for many applications.”

The trailblazing IDE recently garnered yet another major industry award, the Java Developers Journal 2005 Readers’ Choice Award for Best Java IDE. IntelliJ IDEA 5.1 is priced at $499 per license and is available for purchase on the JetBrains’ web site at The IntelliJ IDEA 5.1 upgrade is available free of charge to registered users of version 5.0 via download from
