Hi guys,

i wonder why i get this error could not find or load abc. Basically i am using command prompt to run the java file.

The command is like this: java -cp weka.jar abc then i have that error show above.

Please post the full contents of the window showing all of the error message text.
To copy the contents of the command prompt window:
Click on Icon in upper left corner
Select Edit
Select 'Select All' - The selection will show
Click in upper left again
Select Edit and click 'Copy'

Paste here.

What class files are in the weka.jar file? Is abc the full name of the class you are trying to execute?
