Wordnet indexing error

[Sudarsan, Sithu D.]

Hi All,

We're using Lucene 2.3.2 on Windows. When we try to generate index for
WordNet2.0 using Syns2Index class, while indexing, the following error
is thrown:

Java.lang.NoSuchMethodError:
org.apache.lucene.document.Field.UnIndexed(Ljava/lang/String;Ljava/lang/
String;)Lorg/apache/lucene/document/Field;

Our code is looks like this:

String[] filelocations = {"path/to/prolog/file", "path/to/index"};
try{
     Syns2Index.main(filelocations);
} catch ....


The error typically happens at about line number 130000 in the wn_s.pl
file.

No luck with WordNet3.0 as well. We get the same error.

Any fix or solutions? 

Thanks in advance,
Sithu D Sudarsan
