Inserting CLOBs 32k failed with error "Broken Pipe"

Question

Hi,
We use WLS 8.1 SP2 and Oracle 8i and the oracle thin jdbc driver ojdbc14.jar shipped
with WLS.
Inserting a clob >32k an SQL exception is raised ("Broken Pipe") and the db connection
is becoming stale. Then a restart of WLS is necessary.
Perhaps the current driver doesn't work with 8i ??
Any thoughts?
Thanks in advance

Thanks in advanceThe first thing to do is to try Oracle's latest version of the thin driver.

We switched to Oracle 9.2.0.4.0 and installed the latest thin driver ojdbc14.jar
(for Oracle 9.2.0.3). But there is always the same problem.
Ok. As a last step before contacting Oracle, would you run that code,
changing it to get it's connection directly from the oracle driver?
If the same problem occurs, we can file a TAR with Oracle.

This is the code:
PreparedStatement ps = null;
try {
con.prepareStatement(DBConstants.CREATE_IMPORT_LOG_ERROR);
ps.setLong(1, logId);
ps.setLong(2, recNo);
ps.setInt(3, errorType);
if (rec == null) rec = "NULL RECORD";
CharArrayReader cReader = new CharArrayReader(rec.toCharArray());
ps.setCharacterStream(4, cReader, rec.length());
ps.setInt(5, PDBConstants.IMPORT_LOG_ERROR_STATUS_OPEN);
ps.setString(6, "A");
ps.executeUpdate();
