[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-2237) Oracle driver and BLOB types fail in real world scenario

Oracle driver and BLOB types fail in real world scenario -------------------------------------------------------- Key: HHH-2237 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2237 Project: Hibernate3 Type: Bug

Components: core Versions: 3.2.0.ga Environment: JBoss AS 4.0.4 GA, JBoss Portal 2.4 GA Reporter: Magesh Kumar Bojan Attachments: test.log When JBoss Portal is started up using Oracle 10g (10.2.0.1) and using the Oracle JDBC driver (version 10.2.0.2), and using the JBoss Portal CMS module, if you upload a file, it throws IOExceptions. The file size is arbitrary and should be more than 100KB. Some of the IOExceptions thrown are and not limited to: java.sql.SQLException: Io exception: Bad file descriptor and java.sql.BatchUpdateException: Io exception: Read error Please use the attached test.log for testing. There is a workaround for this as in you can modify the BlobImpl like this and it works: public BlobImpl(InputStream stream, int length) { byte[] bytes = new byte[length]; try { stream.read(bytes,0,length); } catch (IOException e) { e.printStackTrace(); } finally { try { stream.close(); } catch (IOException e) { //ignore } } this.stream = new ByteArrayInputStream(bytes); this.length = bytes.length; } This code is not optimized, but for those who feel they need an urgent fix, this works!
