Retrieving clob locator

Question

I am having trouble retrieving a clob locator from a column despite being able to set it in a previous statement. The clob is always returned as null.
This happens to both an 8.1.6 and 8.1.7 with the latest classes12.zip
Thanks,

Here is my code snippet:
oracle.sql.CLOB clob = null;
// Select LOB locator into standard result set.
StringBuffer sSelect = new StringBuffer();
sSelect.append("SELECT " + mercColName + " FROM BUG" + whereClause.toString() + "FOR UPDATE");
debug.println("Get Clob: " + sSelect.toString());
ResultSet rs =
stmt.executeQuery(sSelect.toString());
while (rs.next()) {
// Get LOB locator into Java wrapper classes.
try {
clob = (oracle.sql.CLOB) rs.getClob(1);
catch (Exception ex) {
//do nothing
if (clob == null)
//update row
StringBuffer sUpdateClob = new StringBuffer();
sUpdateClob.append("UPDATE BUG SET " + mercColName + " = (empty_clob()) " + whereClause.toString());
debug.println("Update Clob: " + sUpdateClob.toString());
stmt.execute(sUpdateClob.toString());
m_DelayConnection.commit();
ResultSet rs2 =
stmt.executeQuery(sSelect.toString());
while (rs2.next()) {
// Get LOB locator into Java wrapper classes.
clob = (oracle.sql.CLOB) rs2.getObject(1);
java.io.Writer writer;
// read data into a character array
char[] data = pval.toCharArray();
// write the array of character data to a CLOB
writer = clob.getCharacterOutputStream();

Found the problem. I was using the ODBC driver instead of the JDBC driver.
