That message means that your Java app can't find a JRE/JDK to run with. How are you trying to execute the Java program? From a command line prompt? or from a shell script?

You may want to check you Path variable to make sure it has the correct JRE included. Or you could try from a command prompt something like c:\path\to\jre.desired.version\bin\java YourProgram

First thing look at the path system variable:
for linux: echo $PATH
for window : path
And see if the location of your jre is listed.
Hope that helps

Select Start, select Control Panel. double click System, and select the Advanced tab.
Click Environment Variables. In the section System Variables, find the PATH environment variable and select it. Click Edit. If the PATH environment variable does not exist, click New.
In the Edit System Variable (or New System Variable) window, specify the value of the PATH environment variable. Click OK. Close all remaining windows by clicking OK
