Could not find or load main class when calling Weka

Question

I apologise for my Java noobness but I am trying to use Weka from console and for some reason I get following error:

Error: Could n         


        

Answer 1

I assume, you use windows, so this is windows command line example. If you get

SET WEKA_HOME=C:\Program Files\Weka-3-7
SET CLASSPATH=%CLASPATH%;%WEKA_HOME%\weka.jar
SET HEAP_OPTION=-Xms4096m -Xmx8192m
SET JAVA_COMMAND=java %HEAP_OPTION%
%JAVA_COMMAND% weka.core.SystemInfo

You should get your system values along with weka values, like weka.version: 3.7.9
