This page describes how to set up and run JMF for Windows. JMF for Windows is an optimized implementation of JMF that contains class files and native libraries for running JMF players.

Setting Up JMF

Run the installation program to extract JMF to a directory, such as C:\Program Files\JMF2.1.1. We'll refer to the directory as %JMFDIR%.

Verify that your CLASSPATH and PATH have been configured properly. During installation, InstallShield should automatically set up your CLASSPATH and PATH.

set CLASSPATH=%JMFDIR%\lib\jmf.jar;%JMFDIR%\lib\sound.jar;.;%CLASSPATH%

Your PATH should be set to include the JMF library files, if you had specified that they not be installed in the Windows\System directory:

set PATH=%JMFDIR%\lib;%PATH%

Running JMF with Netscape Communicator

If Netscape Communicator is already installed on your system when you install JMF, the JMF installation program (with your permission) sets up JMF to work with Netscape Communicator. If the installation program fails to detect Netscape Communicator during installation, there are two ways to get JMF to work with Communicator:

  • You can uninstall JMF 2.1.1 (from the Add/Remove Programs option in the Windows Control Panel) and then install both Netscape Communicator 4.06+ and JMF 2.1.1, in that order. (This is the easier option.)
  • Install Netscape Communicator and then copy the JMF shared libraries and classes to the Netscape directory.
  • From the %WINDIR%\System32 directory or %JMFDIR%\lib directory:
    • Copy jm*.dll and jsound.dll to C:\Program Files\Netscape\Communicator\Program\Java\Bin

    Note:These instructions assume that Netscape Communicator was installed in C:\Program Files\Netscape. If that's not true, substitute the appropriate directories.

Note: JMF requires access to several resources outside the normal Java sandbox. When Communicator brings up dialogs asking you to grant privileges to JMF applets, you should grant them. To avoid the repeated display of security dialogs, you might want to enable "Remember this decision" in the security dialog.
