Getting errors while writing to a BLOB column using PrepareStatement

Question

Hello,
I am getting the following errors when I am trying to insert in a BLOB in the oracle 9i database:
java.sql.SQLException: ORA-00604: error occurred at recursive SQL level 1 ORA-06502: PL/SQL: numeric or value error ORA-06512: at line 205 ORA-22297: warning: Open LOBs exist at transaction commit time
It gets inserted into the BLOB column correctly even after throwing exception.I am using the following code:
String outputXML = outputXML //Some huge string having a length of 52k
String pKey = "DATA-WORKATTACH-URL MELLONFINCORP-GSS-CPG E-444!20061130T211932.030 GMT";
String createDateTime = "20061212T145931.448 GMT";
String createOpName = "Haque, Nadeem";
String createOperator = "ADCDTB6";
String createSystemID = "WFE";
String insName = "TESt INS";
String objClass = "Data-WorkAttach-Note";
String updateDateTime = "20061207T191900.510 GMT";
String updateOpName = "Haque, Nadeem";
String updateOperator = "ADCDTB6";
String updateSystemID = "WFE";
String label = "This is a test for label";
String attachDate = "20061207T191900.510 GMT";
String attachedBy = "Nadeem";
String attachName = "Nadeem Haque";
String note = "This is a test note";
String refObjectKey = "E-438!20061130T211932.030";

Hello,
I am getting the following errors when I am trying to
insert in a BLOB in the oracle 9i database:
java.sql.SQLException: ORA-00604: error occurred
at recursive SQL level 1 ORA-06502: PL/SQL: numeric
or value error ORA-06512: at line 205 ORA-22297:
warning: Open LOBs exist at transaction commit
time
You're doing exactly what the error says, that is committing with an open LOB. Look at the following piece of code: you write in the LOB, you flush it and then commit. There is no closing of the LOB stream before committing.
Try putting the tempBlobOStream.close() instruction before the commit.
// Write the data into the temporary CLOB from the
he byte array
          tempBlobOStream.write(ba);
          // Flush and close the stream
          tempBlobOStream.flush();
nn.commit();
          //Close everything
tempBlobOStream.close();
