Image insertion in Database

Question

Case I:-
int fileLength =(int)ft.length();
PreparedStatement pstmt = con.prepareStatement("insert into image values(1,empty_blob()");
pstmt.setString(1,"MyImage");
pstmt.setBinaryStream(2,fis,fileLength);          
int insertcount = pstmt.executeUpdate();
if(insertcount == 1)
     System.out.println("Image inserted successfully");
          else
               System.err.println("Some Error occured while writing the image to the database");
               throw new SQLException("Some Error occured while writing the image to the database");
          try{
               con.commit(); */
          }catch(Exception et){
          et.printStackTrace();     
          JOptionPane.showMessageDialog(null, "The Image and its record is saved ");
Case II
     String str = "insert into image values(1,empty_blob())";
Statement stmt = con.createStatement();
stmt.executeQuery(str);
str = "select * from image where id = 1" ;
ResultSet rs = stmt.executeQuery(str) ;
if (rs.next())
oracle.sql.BLOB blob = (oracle.sql.BLOB)rs.getBlob("photo");
     File ft=new File(imageName);
     fis= new FileInputStream(ft);
     System.out.println("After Reading the file");
     OutputStream outstream = blob.getBinaryOutputStream();
                    byte buffer[] = new byte [100] ;
                    int length = - 1;
                    System.out.println("Before writing the file");
                    while ((length = instream.read(buffer)) != -1)
                    outstream.write(buffer, 0, length);
Case I : The Exception occur as : TNS End Data Channel
Case II: The insert take place but the value of Orablob is NULL
     If You have any Workable code for just inserting the image and reteriving it just send the code i will try it

Hi,
try something like that, it works for inserting. For getting image from database use the second select within changing of input and output streams.
target = new File("Pictures\\" + tarName + ".jpg");
String sqlCommand0 = new String("INSERT INTO T_PICTURES VALUES(?,sysdate,empty_blob())");
String sqlCommand1 = new String("SELECT CODE, PICTURE FROM T_PICTURES WHERE code ='"+ tarName +"' FOR UPDATE");
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@pxedms:1521:cam1",user.getUsr(), user.getPass());
conn.setAutoCommit(false);
PreparedStatement pstmt = conn.prepareStatement(sqlCommand0);
pstmt.setString(1, tarName);
pstmt.execute();
pstmt.close();
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery(sqlCommand1);
while(rset.next()){
FileInputStream inFile = new FileInputStream(source);
FileOutputStream outFile = new FileOutputStream(target);
int c;
BLOB blobFile;
OutputStream oraOut;
blobFile = ((OracleResultSet)rset).getBLOB(2);
oraOut = blobFile.getBinaryOutputStream();
while((c = inFile.read()) != -1){
outFile.write(c);
oraOut.write(c);
outFile.close();
oraOut.close();
stmt.close();
rset.close();
conn.commit();
conn.setAutoCommit(true);
conn.close();
