Installing the Java Runtime Environment (JRE)

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:
 

1.  If you're using Windows 95/NT or Solaris, from your browser, go to this page.  Otherwise, look up the pointer on the Unidata Java Resources site.

 
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.  In Windows: after downloading it, run the .exe file and follow the wizard through the install process; you may need to restart your machine when you're done with the install
   
   
4. If you are using a Windows OS, please read this important note and follow the instructions therein before going any farther.

 
5.  afterwards, open a Command Prompt window and type:


    jre <enter>

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

    Java(tm) Runtime Loader Version 1.1.x

followed by usage information.  If instead of this response, you get something like "command jre 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.
