Recommended Hardware Configurations

NetBeans IDE is also known to run on the various other Linux distributions such as Oracle Linux 5, Ubuntu 8.x, Red Hat Enterprise Linux, Fedora 14, and many others.

Note: NetBeans Web and Java EE support are particularly demanding on system resources - especially when used in combination with application servers. While the above system requirements apply to most configurations of the IDE, for the best results make sure that your system meets at least the recommended system requirements when developing Web and Java EE applications.

Required Software

NetBeans IDE runs on the Java SE Development Kit (JDK) which consists of the Java Runtime Environment plus developer tools for compiling, debugging, and running applications written in the Java language.

The tested JDK for this release is JDK 7u21 for Windows, Linux, Solaris and OS X. The 7.3.1 version of the IDE cannot be installed or run using JDK 5.0.

Note: The PHP and C/C++ NetBeans bundles only require the Java Runtime Environment (JRE) 6 or 7 to be installed and run.

You can download the JDK for your platform from one of the sites listed below:


JavaFX Support

The JavaFX 2.2.5 SDK (and later) is not bundled with the NetBeans IDE 7.3.1 release. You can install it together with Java SE Development Kit 7u21 as a co-bundled product.
Please note the following:


SQL Editor and Databases

The following changes have been made to the database functionality in NetBeans IDE 7.3.1:


Multilingual Support Information

NetBeans IDE is translated into the following languages: Brazilian Portuguese (BR), Japanese (JP), Simplified Chinese (ZH), and Russian (RU).

Community translations of the IDE are also available in several additional languages and can be downloaded from the Community Contributed section of the IDE Language drop-down menu.


Compatibility with Earlier Releases

When the IDE is run for the first time after installation you have the option to import some of the settings used in a previous installation. The IDE opens using the default settings if you choose not to import the settings from the existing installation. Note the IDE only recognizes previous installations when the user directory resides in the default location. It does not recognize installations that use the --userdir switch to specify a user directory. If you would like to import settings from a location that the installer does not recognize do the following:

  1. Start the IDE go to Tools > Options in the main menu.
  2. Click the Import button at the bottom of the Options dialog.
  3. In the Select Options to Import dialog, click the Browse button and navigate to the user directory that contains the settings you want to import. For more about the location of the NetBeans IDE userdir, see the FAQ What is a userdir and where can I find it?


Archived Modules and Features

The NetBeans IDE is no longer bundled with the Java ME SDK. The Java ME SDK is available for download at the Java ME SDK Download page. You can find the instructions on installing Java ME SDK 3.2 into NetBeans IDE 7.3.1 on Windows in the Java ME SDK Support FAQ.
