Hi all,
I'm trying to load Genbank sequence into BioSQL database with
BioJavax/Hibernate. It's Ok to load the first sequence. Then I got the
exception when loading new sequences or reloading the same sequence.
Seems the Hibernate is trying to insert "genbank" namespace again. Can
anybody tell me what I did wrong? Thanks in advance.

public class SequenceLoaderNew {
public void loadSeq(String fileName, String namespace) throws
FileNotFoundException, BioException {
System.out.println("Start loading file " + fileName + " at " +
System.currentTimeMillis());
BufferedReader br = new BufferedReader(new FileReader(fileName));
Session session = new
Configuration().configure().buildSessionFactory().openSession();
RichObjectFactory.connectToBioSQL(session);
RichSequenceDB db = new BioSQLRichSequenceDB(session);
RichSequenceIterator rsi =
RichSequence.IOTools.readGenbankDNA(br, new SimpleNamespace(namespace));
while (rsi.hasNext()) {
Transaction tx = session.beginTransaction();
RichSequence sequence = rsi.nextRichSequence();
System.out.println("Loaded sequence" +
sequence.getAccession() + ", identifier: " + sequence.getIdentifier());
try {
System.out.println("Delete sequence" +
sequence.getAccession() + " if exists.");
db.removeSequence(sequence.getAccession());
} catch (Exception ex) {
}
try {
System.out.println("Save sequence " +
sequence.getAccession());
session.save("BioEntry", sequence);
tx.commit();
session.flush();
session.clear();
} catch (HibernateException ex) {
tx.rollback();
ex.printStackTrace();
}
}
}
public static void main(String[] args) throws BioException,
FileNotFoundException {
SequenceLoaderNew sl = new SequenceLoaderNew();
//sl.loadSeq("/genomeseq/bacteria/NC_005813.gbk", "genbank");
sl.loadSeq("/genomeseq/bacteria/NC_004349.gbk", "genbank");
}
