Summary: Oracle BLOB and byte array
Initial Comment:
Re-submiting a bug that was never fixed and closed.
The Orginial problem was
> [ 434620 ] Oracle BLOB and byte array
The Conclusion was
> If this problem persists with JBoss 2.4 or 3 then please
> report it again. JBoss 2.2 is not supported anymore.
I can confirm that this is still a bug in 2.4.
JBoss: JBoss-2.4.4_Jetty-3.1.7-1
OS: Windows 2K and Windows NT
JDK: 1.4
DB: Oracle 8.1.6
The suggested fix in [434620] works for me but hasn't
been integrated into jboss and presumably hasn't
been tested against other DBs.

dsundstrom wrote that this patch has been integrated into
JBossCMP (jboss3 cmp-2.0 engine?)(exactly into
org.jboss.ejb.plugins.cmp.jdbc.JDBCUtil) . So, I think, it is
related. I've got the latest source code (2002.06.18) from
SourceForge and it's not working due to earlier exception. I'm
using only CMP entity beans where some of them have BLOB
cmp fields (I'm not writing BLOBs on my own)

Your problem appears to be un-related. This bug was to
do with reading blobs, and it only effected
org.jboss.ejb.plugins.jaws.jdbc.JDBCCommand, you seem
to have problems writing blobs.

Is this working? I've got following exception with oracle driver
(8.1.7):
java.lang.ClassCastException:
org.jboss.ejb.plugins.cmp.jdbc.ByteArrayBlob
at oracle.jdbc.driver.OraclePreparedStatement.setBlob
(OraclePreparedStatement.java:1446)
at
org.jboss.resource.adapter.jdbc.local.LocalPreparedStatement.set
Blob(LocalPreparedStatement.java:680)
at
org.jboss.ejb.plugins.cmp.jdbc.JDBCUtil.setParameter
(JDBCUtil.java:220)
at
org.jboss.ejb.plugins.cmp.jdbc.bridge.JDBCAbstractCMPFieldBrid
ge.setArgumentParameters
(JDBCAbstractCMPFieldBridge.java:283)
In oracle driver (OraclePreparedStatement) is:
public synchronized void setBlob(int i, Blob blob)
throws SQLException {
setBLOB(i, (BLOB)blob);
}
The same code is in the current release (9.2.0.1) of oracle driver.

This patch has been integrated into JBossCMP (HEAD) with
some slight modifications (see original patch for details).
I NEED YOU TO TEST THIS (IN HEAD)
