On quick look that code looks fine, though removeField is an expensive
operation and unnecessary for this.
We really need the full traceback of the exception.

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

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. The Chandler project created this for PyLucene because
they were
having trouble with GCJ:
