java classpath error using LibSVM programmatically within Weka

Question

I'm trying to use LibSVM programmatically in Java, via the Weka wrapper written by El-Manzalawy, running on Windows 7. I've added C:\Program Files (x86)\libsvm-3.12\java\libsvm.jar to my CLASSPATH environmental variable. After adding that I can now use LibSVM via the Weka explorer user interface, but it still fails when I'm calling it in code (debugging in eclipse).

I try to create it using Weka.core.Utils.forName. This goes through to LibSVM.java which then calls the java method Class.forName(...), passing CLASS_SVM as the param which is set to "libsvm.svm".

I've used Weka.core.Utils.forName to create others classifiers programmatically without problems.

Anyone have any ideas?

You should be able to glue libsvm and weka in your java program using the answer posted here: How to use LibSVM with Weka in my Java code?
