Factory in Solr

[Heba Farouk <He...@bibalex.org>]

Hello there

I'm trying to add a factory in solr for tokenizing Arabic text, but I
receive some error (the one at the last of my email)

 

Here is my code:

 

package org.apache.solr.analysis;

 

import gpl.pierrick.brihaye.aramorph.lucene.ArabicTokenizer;

 

import java.io.Reader;

 

import org.apache.lucene.analysis.TokenStream;

import org.apache.solr.analysis.BaseTokenizerFactory;

 

 

public class ArabicTokenizerFactory extends BaseTokenizerFactory{

      public TokenStream create(Reader input) {

          return new ArabicTokenizer(input);

      }

}

 

 

Can u help me

 

Thanks in advance

"VerrifyError" is a pretty low level JVM error ... based on that message 
i'm guessing that the version of the TokenStream class you compiled 
against isn't the same version being used when you run Solr ... if you 
compile your factory using the jars that come with Solr in your 
classpath (and no other versions of lucene jars) it should work.
