Installing the Java Runtime Environment (JRE)

updated 4/1/2005

Before you can use the VISITview in local mode, you must have the Java Runtime Environment installed and running properly on your machine.  Installation only takes a few minutes.  Follow these steps:

If you are using Windows 95/98/NT/2000/XP then VISITview comes with the Java Runtime Envrionment you need...and you do not need to install it separately. If you want to do a "standard" installation of Java, however, continue on......

  1.  If you're using Unix, or running from your browser, go to this page and get a version of Java 1.3.1 or later.
  2.  follow the menus; be sure to get the JRE (unless you intend to do Java development, then get the JDK). Note that the JRE may not be available separately for all different operating systems.
  3.  After installing the Java Runtime, open a Command Prompt (Terminal) window and type:

  4.     java <enter>

    If the JRE installed okay, the response should be something like:

        Java(tm) Runtime Loader Version 1.3.x

    followed by usage information.  If instead of this response, you get something like "command java not found", the most likely cause is that your PATH environment variable was not properly set to include a path to the directory containing the jre.exe.  If this is the case, you should modify the PATH to include this directory.
