Subject Snowball filter - Error instantiating stemmer for a language
Date Thu, 04 Sep 2014 10:25:21 GMT
I am trying to use some filters from the snowball package. However, when I
run the following code:

Map<String,String> args = new HashMap<>();
TokenStream tokenStream = new StandardTokenizer(Version.LUCENE_46, new
StringReader("Some text"));
args.put("luceneMatchVersion", "4.6");
args.put("language", "Catalan");
SnowballPorterFilterFactory factory = new SnowballPorterFilterFactory(args);
TokenFilter filter = factory.create(tokenStream);

I got the following error:

Exception in thread "main" java.lang.RuntimeException: Error instantiating
stemmer for language Catalanfrom class null
	at
org.apache.lucene.analysis.snowball.SnowballPorterFilterFactory.create(SnowballPorterFilterFactory.java:79)
	at analysis.AutoLanguageAnalyizer.main(AutoLanguageAnalyizer.java:205)
Caused by: java.lang.NullPointerException
	at
org.apache.lucene.analysis.snowball.SnowballPorterFilterFactory.create(SnowballPorterFilterFactory.java:77)
	... 1 more


Any idea on how to resolve this.

Thanks in advance.

Regards
Ameer
