Jdbc Clob

Question

When Iam trying to save data into clob type of oracle using Pooled Connection it is giving the following exception
java.lang.ClassCastException: weblogic.jdbc.rmi.SerialResultSet at....
But it is saving fine with Normal connection. Iam using Weblogic 6.1(sp2) and Oracle 9.9.1.1.1 with thin drivers.
The code is like this
select clob_col from tablename for update;
oracle.sql.CLOB objClob=((OracleResultSet)objResultSet).getCLOB(strColumnName);
                              Writer objClobWrite=objClob.getCharacterOutputStream();
Please help me on this issue.

PhaniWhen u r using clob or blob from weblogic you have use classes from package weblogic.jdbc.rmi
for uploading a clob do it like
ps = conn.prepareStatement("select data from urtable where ID=? for update");
ps.setString(1, ID);
ResultSet rsclob = ps.executeQuery();
if(rsclob.next()) {
weblogic.jdbc.rmi.SerialClob dclob = (weblogic.jdbc.rmi.SerialClob)rsclob.getClob(1);
try {
Writer datawrt = (Writer)dclob.getCharacterOutputStream();
datawrt.write(msg);
datawrt.flush();
datawrt.close();
catch(IOException iex) {
throw new Exception("Error while writing clob object");
rsclob.close();
u can do the similiar thing for Blob as well.
