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 7u9 for Windows, Linux, Solaris and OS X. The 7.2.1 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 SDK is required to use JavaFX features in the NetBeans IDE 7.2.1. You can download the JavaFX 2.2 SDK from the JavaFX download site.

Note:

  • JavaFX 2.2 is bundled with the latest JDK 7 for Windows, Mac and Linux.
  • If you install the JDK 7 Update 6 or newer to default locations, the NetBeans IDE can create a JavaFX-enabled Java platform automatically.
  • To use JavaFX features in the NetBeans IDE, we strongly recommend upgrading your JDK version to JDK 7 Update 6 or newer.

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?

    Workaround: Before the installation, remove all big zip files from the desktop.

top

Core IDE

The unresolved Core IDE issues for this release are as follows:

  • Difficulties starting the IDE (Solaris x86 and Dual-Core Opteron).

    Description: On certain Solaris x86 and Dual Core Opteron configurations, you may encounter problems starting the IDE due to a JDK bug with loading GTK look&feel libraries.

    Workaround: If you encounter this behavior, specify the following command line option: -laf javax.swing.plaf.metal.MetalLookAndFeel

  • Characters do not display properly in some Asian locales.

    Description: When running the IDE with some Asian locales on Ubuntu and some other Linux distributions, the IDE's screen text may become unreadable. On certain Linux distributions multi-byte characters may display as a rectangle due to JDK font setting issues.

    Workaround: Please see the FAQ for help with resolving this issue: http://wiki.netbeans.org/FaqI18nLinuxAsianFonts

  • Issue #88776: Profiled application can crash when profiling using dynamic attach mode.

    Description:When running on JDK 1.6, profiling an application with dynamic attach mode can lead to the profiled application crashing.

    Workaround: Start the application you want to profile with the -Xshare:off switch.
    See also Issue #113847.

  • Issue #110074: Editor periodically freezes on Solaris.

    Description: When running the IDE on Solaris with JDK 6, 6u1 or 6u2, threads may become blocked for a long time and cause the editor to be unresponsive.

    Workaround: Upgrade your JDK 6 installation to Update 3 or newer.

  • Issue #119617: Cursor lost in editor and cannot type using keyboard.

    Description: It can sometimes occur that after using a hint in the editor window that the insertion point in the editor disappears and you cannot type using the keyboard. This has mostly been reported on Mac OS X 10.4, but there have been some reports on some versions of Ubuntu.

    Workaround: Use the mouse to open and then close a dialog window (for example, a properties dialog). This returns the focus to the editor and the insertion point and keyboard will work as normal.

  • Issue #130357: I18N - OS X will not generate javadoc if the project name or path has multibyte characters.

    Description: The javadoc task is written in MacRoman, the default OS X encoding, when creating the temporary parameter file. This may be due to the BSD and Mach parts (system & kernel calls) accepting parameters in UTF-8, but the OS X and HFS only accepting MacRoman.

    Workaround: Avoid using multibyte characters in the name of the project or the path to the project.

  • Issue #200826: On Windows 7, newly installed IDE running on JDK 7 won't connect to network.

    Description: In some cases the firewall of the local system may filter responses from the network while connecting to a remote host. When connecting to a remote host the JDK will first attempt to use IPv6 and then IPv4. The firewall may filter out a negative response from the host when using IPv6 with the result that the JDK does not attempt to connect to the host using IPv4.

    Workaround: Modify the netbeans.conf to add the -J-Djava.net.preferIPv4Stack=true command line switch, or modify the NetBeans options of the environment variable.

  • Issue #207060: On Windows XP, UNC paths cannot be used as URIs.

    Description: On Windows XP, the automatic update of any file view (Project, Files, etc.) does not work when UNC style paths are used (for example, \\MyServer\myShare\myDirectory) instead of drive letters (for example, Y:\myDirectory).

    Workaround: Restart the IDE. Alternatively, choose Tools > Options > Miscellaneous > Files from the main menu, deselect the Enable auto-scanning of sources option, and select Refresh Folder in the context menu of a folder.

  • Issue #211406: Views and Palettes keeps scrolling itself to the drag position after drag-and-drop.

    Description: After dragging and dropping something from Projects or Files Views or Palette in GUI designers, when you scroll the View or Palette up or down it will scroll back to the drag position, requiring you to scroll to select some nodes and components.

    Workaround: You must restart the IDE.

  • Issue #215141: IDE on a Retina Macbook is very blurry

    Description: The IDE appears blurry when viewed on a Retina display.

    Workaround: Run the IDE on JDK 6.

  • Issue #217817: IDE becomes unresponsive on Mac OS X running on JDK 7u9 and earlier.

    Description: The IDE might become unresponsive on OS X when running on JDK 7u9 and previous updates of JDK 7.
