File saving in DB. Please, help!!!!!!!!

Question

Hello,
I need your help very very much.
My data base is Oracle 9i.
I'd like to save file as Blob in the table of the data base.
What I have to do?

Answer 1

To write to blob
import oracle.sql.*;
import oracle.jdbc.driver.*;
//variables
oracle.sql.BLOB blob = null;
try {
     StringBuffer sbf = new StringBuffer();
     try {
          // fileObject is the file you wish to read
          FileInputStream fin = new FileInputStream(fileObject);
          long fileLen = fileObject.length();
          int counter = 0 ;
          while ( counter < fileLen ) {
               char c = (char) fin.read();
               sbf.append(c);
               counter++;
     } catch ( Exception e ) {
          throw e ;
     byte[] bArray = sbf.toString().getBytes();
     //get databse connection
     Class.forName(DRIVER_NAME);
     connection = DriverManager.getConnection(DATABASE_INFO,username,password);
     //execute query
     query = "select BLOB_FIELD from TABLE_NAME FOR UPDATE";
     statement = connection.createStatement();
     resultset = statement.executeQuery(query);
     while (resultset.next()) {
          blob = ((OracleResultSet)resultset).getBLOB("BLOB_FIELD");
     OutputStream outputStream = blob.getBinaryOutputStream();
     int bytes_a_time = 2048;
     int bytesWritten = 0;
     int start = 0;
     int length = bArray.length;
     if (bytes_a_time > length) {
          bytes_a_time=length;
     while (bytesWritten < length) {
          outputStream.write(bArray,start,bytes_a_time);
          start = (start + bytes_a_time);
          bytesWritten = bytesWritten + bytes_a_time;
          if ((bytesWritten+bytes_a_time) > length) {
               bytes_a_time=length-bytesWritten;
}catch(Exception e){
To read blob value
//variables
bArray     = null;
oracle.sql.BLOB blob = null;
try {
     //get databse connection
     Class.forName(DRIVER_NAME);
     connection = DriverManager.getConnection(DATABASE_INFO,username,password);
     //execute query
     query = "select BLOB_FIELD from TABLE_NAME";
     statement = connection.createStatement();
     resultset = statement.executeQuery(query);
     while (resultset.next()) {
          blob                = ((OracleResultSet)resultset).getBLOB("BLOB_FIELD");
          int length          = (int)blob.length();
          byte[] bArray     = new byte[length];
          bArray                = blob.getBytes(1,length);
}catch(Exception e){
