"Classcast Exception using Oracle Blobs(10g) and JBoss 4.0" To view the discussion, visit: http://community.jboss.org/message/563449#563449 -------------------------------------------------------------- Hi all, Im using oracle 10g and JBoss 4. Im getting the following error : java.lang.ClassCastException : oracle.sql.BLOB Conn = DBConnector.getConnection(); // Initially inserted an empty_blob() to data base //retrieving the record and locking it. PreparedStatement pStatement = conn.prepareStatement("Select ............... for Update") ResultSet result = pStatement.executeQuery(); System.out.println(result.getClass().getName()); result.next(); BLOB blob =((OracleResultSet)result).getBLOB(1); OutputStream outStream = blob.setBinaryStream(1L); int size = blob.getBufferSize(); byte[] buffer = new byte[size]; int length = -1; while ((length = inputStream.read(buffer)) != -1) outStream.write(buffer, 0, length); inputStream.close(); outStream.close(); Ive also tried casting my ResultSet obj with WrappedResultSet of org.jboss.resource.adapter package. This is also throwing a classcastexception. Please provide a solution.
