Porter Stemmer and Weka

Question

I am using Weka with the porter Stemmer provided in the SnowBall package. Everything works fine if I run my application within Eclipse, but as soon as I export it as runnable jar (With all the libraries included) weka says:

Stemmer 'porter' unknown!

How could I fix that?

Answer 1

The Snowball jar is not in your classpath, as described in the wiki. When you run your jar, you need to make sure the Snowball jar is in your classpath. You could also unpack the Snowball jar and include it in your project.
