The scenario is quite simple: I'm using the database to store Genbank
genome sequences. Later I've to update the sequences when Genbank has
newer releases. The following two lines are loading the same sequence
twice. The first time will insert a new BioEntry record. the second time
will delete the existing record and insert a new record again.
sl.loadSeq("/genomeseq/bacteria/NC_005813.gbk", "genbank");
sl.loadSeq("/genomeseq/bacteria/NC_005813.gbk", "genbank");
Following code is used to load multiple genome sequences by calling the
loadSeq() method multiple times. All failed except the first time.
sl.loadSeq("/genomeseq/bacteria/NC_005813.gbk", "genbank");
sl.loadSeq("/genomeseq/bacteria/NC_006723.gbk", "genbank");
sl.loadSeq("/genomeseq/bacteria/NC_008945.gbk", "genbank");
The exception message has the details. Since all variables used in loadSeq()
are local, and I did the session flush/clear/close, then it should be ok to
call the method again.
Thank you very much for your help.

I'm not sure why you'd want to do that? Either way, as far as I know,
Hibernate sessions are not designed for that. If you want to delete
the sequence then replace it with a completely new sequence object,
you have to create a new sequence object - you can't reuse the one you
just deleted. The session info is embedded into that object so even if
you clear the session, the object still refers to it.
If you just want to load a sequence, modify it, then save it back, you
should just load it then use saveOrUpdate to save it back again with
changes. If you want to replace objects in your database, don't load
them, just delete them, then use save to create new objects in their
place.

2008/5/21 gang wu <[EMAIL PROTECTED]>:
I got another problem with almost the same code(see attached code and
output). If I call the loadSeq() only once, everything works fine. The
second call of the same method will fail. By the exception message, it looks
like the session is not cleaned up yet though at the end of the method the
session has been flush/clear/closed. Anything wrong?
Or does anyone have a sequence data loader would like to share? I'm quite
frustrated after keeping trying to do this seems simple thing without
success. If I can make it work, I'd like to post it on the mailing list.
Thanks in advance.

You need to substitute this line:
RichSequenceIterator rsi = RichSequence.IOTools.readGenbankDNA(br, new
SimpleNamespace(namespace));
with this line:
Namespace ns =
(Namespace)RichObjectFactory.getObject(SimpleNamespace.class,new
Object[]{namespace});
RichSequenceIterator rsi = RichSequence.IOTools.readGenbankDNA(br, ns);

PS. You're the second person who has quoted this section of code on

from a website somewhere, could you send me the URL so I can get in
touch with the authors and get them to correct it? Thanks!

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.
