Thanks Michael and Ian for your valuable response. I am attaching a small default code. Please have a look and tell me where am I going wrong.
import lucene from lucene import Document, Field, initVM, CLASSPATH doc = Document() fieldA = Field('fieldA', "", Field.Store.YES, Field.Index.UN_TOKENIZED) fieldB = Field('fieldB', "", Field.Store.YES, Field.Index.TOKENIZED) fieldC = Field ('fieldC', "", Field.Store.YES, Field.Index.TOKENIZED) doc.add(fieldA) doc.add(fieldB) doc.add(fieldC) def get_fields(): if doc.getField('FieldA') is not None: doc.removeField('FieldA') if doc.getField('FieldB') is not None: doc.removeField('FieldB') if doc.getField('FieldC') is not None: doc.removeField('FieldC') fieldA.setValue("abc") doc.add(fieldA) fieldB.setValue("xyz") doc.add(fieldB) fieldC.setValue("123") doc.add(fieldC) return doc def add_document(): doc = get_fields() writer = lucene.IndexWriter(index_directory, analyzer, create_path) writer.addDocument(doc) writer.close() This writer.addDocument is throwing an exception saying java.lang.NullPointerException Thanks, Aditi On Tue, Aug 19, 2008 at 3:25 PM, Michael McCandless < [EMAIL PROTECTED]> wrote: > > Ian Lea wrote: > > I don't think you need to remove the field and then add it again, but >> I've no idea if that is relevant to your problem or not. >> > > That's right: just leave the Field there and change its value (assuming the > doc you are changing to still uses that field). > > A full stack trace would be more help, and maybe an upgrade to 2.3.2, >> and maybe a snippet of your code, and what is JCC? >> > > JCC generates the necessary C/C++ glue code for Python to directly invoke > Java code.
