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
