I would like to use the WEKA library in a Java program but I can't seem to find the methods I installed using WEKA's package manager.

Does anyone know where the installed methods are stored?

For clarification, I installed WEKA, installed the extra package using WEKA and can use it with the WEKA GUI. But I can't find the installed package in the .lib file.

  • $\begingroup$ Fyi you only need to locate the file weka.jar which contains all the weka libraries $\endgroup$ – Erwan Dec 9 '19 at 15:51
  • $\begingroup$ Thanks for the comment Erwan, not all packages are in the weka.jar. When you install a package using their package manager, they're stored in the packages folder, which I didn't know existed until now. $\endgroup$ – abdnChap Dec 9 '19 at 16:03
  • $\begingroup$ Oh ok sorry I didn't know that, thanks! $\endgroup$ – Erwan Dec 9 '19 at 16:06
  • $\begingroup$ That's why I posted the question, I couldn't find the method I wanted in the jar and didn't know packages were stored elsewhere. Hopefully others will see my answer and won't spend as much time looking as I did haha $\endgroup$ – abdnChap Dec 9 '19 at 16:08

I don't know how WEKA stores the extra packages on other installations, but for my Windows 10 with WEKA 3.8 it was here:

WEKA stores the extra packages in a direcory called packages. This package was in my user directory and under the wekafiles folder.

Example: "C:\Users\myUser\wekafiles\packages....."

Hope this helps someone else.
