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

You can provide the class path with the -cp param:

java -cp /path/to/weka/weka.jar weka.classifiers.trees.J48 ...
# on Windows, this is probably something like 
java -cp C:\path\to\weka\weka.jar weka.classifiers.trees.J48 ...
