How to use libsvm in weka

Question

I am unable to use lib svm in weka.

I have followed the steps here and did much googling but to no avail.

How to use LibSVM with Weka in my Java code?

I would just need this code

LibSVM classifier = new LibSVM()

to work.

But however it keeps on cannot detect the LibSVM library

What am i doing wrong?

i cannot get the jar

You can get the wlsvm.jar from here: http://www.cs.iastate.edu/~yasser/wlsvm/

from here as proposed in the solution.

Is there anyway i can install LIBSVM into weka using the GUI then extracting the jar out?
