Hi Andy
Thanks for answering my question.Is this code only for version 3.0 and higher?
Do we need to close the model or commit and end the dataset are enough?
ThanksAbdul

The correct form (all 3.x versions):
Dataset dataset = TDBFactory.createDataset(location);
dataset.begin(ReadWrite.WRITE) ;
try {
// Inside begin-commit.
Model model = dataset.getDefaultModel();
// write triples to model
dataset.commit() ;
} finally {
dataset.end() ;
}
