!2 What to Do If You Have the Wrong Java Runtime Environment
FitNesse requires version 1.5 or later of the Java Runtime Environment (JRE).
If you see the messages:
''!-C:\fitnesse>java -jar fitnesse.jar-!
!-Exception in thread "main" java.lang.NoClassDefFoundError:-!
!-java/lang/CharSequence-!
!- at fitnesse.FitNesse.parseCommandLine(Unknown Source)-!
!- at fitnesse.FitNesse.main(Unknown Source)-!
!-C:\fitnesse>pause-!
!-Press any key to continue . . .-!''
Then you need to download and install version 1.5 or later of the JRE. Follow these steps:
* Press a key to close the command window
* Go to [[this download link][https://jsecom15a.sun.com:443/ECom/EComActionServlet;jsessionid=jsecom15a.sun.com-9752%3A415dafbe%3A147685f2fbcc1de1]].
* Accept the terms of agreement (if you are permitted), and click Continue.
* Download the right JRE installer for your machine and operating system.
* Launch the installer, and follow its instructions to install JRE 1.5 or later.
* Change the PATH environment variable so that it points to the new JRE.
* Go to the /bin folder that contains java.exe, and copy the pathname (for example, ''C:\Program Files\Java\j2re1.5.0_13'')
* Go to Settings>Control Panel>System>Advanced>Environment Variables>PATH>Edit
* Paste in that same complete pathname
* Save the PATH environment variable, and close the System control panel
* Double-click run.bat again.
* Return to DownloadingAndInstallingFitNesse.
