Problem inserting clob value into xmltype column

Question

Hi all,
I have created a table in XML DB using as:
CREATE TABLE TransDetailstblCLOB ( id number, data_xml XMLType) XmlType data_xml STORE AS CLOB;
I am trying to insert large xml data into the data_xml column which is of type XMLTYPE.
I followed this link (http://www.oracle.com/technology/sample_code/tech/java/codesnippet/xmldb/HowToLoadLargeXML.html) to create a clob object and insert into xml.
I am getting the following error:
ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00229: input source is empty
Error at line 0
ORA-06512: at "SYS.XMLTYPE", line 254
ORA-06512: at line 1
My code snippet:
private static CLOB getCLOB(String xmlData, Connection conn) throws SQLException{
     CLOB tempClob = null;
     if(conn==null){
          log.debug("Connection object is null");
          throw new SQLException("Connection object is null");
     try{
     // If the temporary CLOB has not yet been created, create new
     tempClob = CLOB.createTemporary(conn, true, CLOB.MODE_READWRITE);
     // Open the temporary CLOB in readwrite mode to enable writing
     tempClob.open(CLOB.MODE_READWRITE);
     // Get the output stream to write
     writer = tempClob.getCharacterOutputStream();
     writer.write(xmlData);
     } catch(SQLException sqlexp){
          tempClob.freeTemporary();
     sqlexp.printStackTrace();
     } catch(Exception exp){
     tempClob.freeTemporary();
     exp.printStackTrace();
     return tempClob;      
public static void insertXML(String xmlData, Connection conn){
     CLOB clob = null;
     String query;
     log.debug("Inside insertXML" +xmlData);
     try{
     query = "INSERT INTO TransDetailstbl1(data) VALUES (XMLType(?)) ";// Changed prev TransDetailstbl
     // Get the statement Object
     pstmt = conn.prepareStatement(query);
     //      xmlData is the string that contains the XML Data.
     // Get the CLOB object using the getCLOB method.
     clob = getCLOB(xmlData, conn);
     // Bind this CLOB with the prepared Statement
     pstmt.setObject(1, clob);
     int i =pstmt.executeUpdate();
     log.debug("pstmt.executeUpdate () status ::: "+i);
     // Execute the Prepared Statement
     if (i == 1) {
     log.debug("Record Successfully inserted!");
     } catch(SQLException sqlexp){
     sqlexp.printStackTrace();
     } catch(Exception exp){
     exp.printStackTrace();
     finally{
          try{
               pstmt.close();
//           Flush and close the stream
               writer.flush();
               writer.close();
          // Close the temporary CLOB
          tempClob.close();
          catch(Exception e)
               log.debug("Cant close prepared statement.");
               e.printStackTrace();
Can anyone help me out?
Please let me know if any other info is required.

Hi all,
I now modified the code to write the data using Stream.
I am getting this error message: SQLException while updateORA-24813: cannot send or receive an unsupported LOB
On googling it seems the its usually caused when I am using the different versions of oracle on
server and client.
My oracle details:
Database product version : Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - Production
With the Partitioning, OLAP and Data Mining options
JDBC driver name : Oracle JDBC driver
JDBC driver version : 9.2.0.1.0
DataStoreHelper name is: com.ibm.websphere.rsadapter.OracleDataStoreHelper@22542254.
JDBC driver type : thin
Can anyone tell me how to proceed?
Thanks
