Postgresql 8.4 reading OID style BLOBs with Hibernate
- by peter
I am getting this weird case when querying Postgres 8.4 for some records with Blobs (of type OIDs) with Hibernate. The query does return all right but when my code wants to read the content of the BLOB with the simple code below, it gets 0 bytes back
public static byte[] readBlob(Blob blob) throws Exception {
InputStream is = null;
try {
is = blob.getBinaryStream();
return org.apache.commons.io.IOUtils.toByteArray(is);
}
finally {
if (is != null)
try {
is.close();
}
catch(Exception e) {}
}
}
Funny think is that I am getting this behavior only since I've started adding more then one such records to the table.
The underlying JDBC library is type 3 (postgresq 8.4-701).
Can someone give me a hint as to how to solve this issue?
Thanks
Peter
