[Biojava-dev] Re: MORE Oracle BioSQL & BioJava problems

Hi Hilmar,
The DB target is Oracle 9i (9.2.0.4) running on SUSE Linux 9x.
I do believe the problem occurs on sequences that are > 4000 chars.
The offending Java code appears to be:
PreparedStatement create_biosequence = conn.prepareStatement("insert into
biosequence " + "(bioentry_id, version, length, seq, alphabet) " + "values
(?, ?, ?, ?, ?)");
String seqstr = seqToke.tokenizeSymbolList(seq);
create_biosequence.setCharacterStream(4, new StringReader(seqstr),
seqstr.length());
In all Java/Oracle applications we've developed, we've always inserted an
empty_clob(), and then updated the clob separately using the record locator.
I am a little apprehensive to hack the Opensource code, just because I want
to stay in sync with the BioJava releases...
Has anyone else using BioJava/BioSQL in Oracle run into this problem?
Thanks in advance!
MG
