Odd ... the class org/tartarus/snowball/ext/CatalanStemmer.class should exist in the same jar as SnowballPorterFilterFactory, can you please confirm that you see it there?
$ jar tf lucene-analyzers-common-4.6-SNAPSHOT.jar | grep CatalanStemmer org/tartarus/snowball/ext/CatalanStemmer.class The only explanation i can think of is that maybe you manually copied some of the java or class files directly into your project instead of using hte jars? if not: can you describe a bit more about your project and how you are running this code? what does the classpath look like exactly? : Date: Thu, 4 Sep 2014 03:25:21 -0700 (PDT) : From: atawfik <contact.txl...@gmail.com> : Reply-To: java-user@lucene.apache.org : To: java-user@lucene.apache.org : Subject: Snowball filter - Error instantiating stemmer for a language : : I am trying to use some filters from the snowball package.
