SQLSERVER and BLOB

Question

Hello,
I m trying to insert/retrieve an image from a SqlServer 2000 DB, I have a [Microsoft][SQLServer 2000 Driver for JDBC]. Im allways getting (String or binary data would be truncated.). Can anyone help me , I ve already looked in this forum and on the net but I cant put this to work, I dont know if it is a problem with the table definition or other thing...
my table in sqlserver:
CREATE TABLE DBTEST.dbo.ImageTable ( ImgName VARCHAR PRIMARY KEY, MyImage image );
My code:
public class ImageStream {
     public static void main(String[] args) {
          ImageStream i = new ImageStream();
          i.put("ssfsf");
     void put(String file){
     try{     
          Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver" );
          String url = "jdbc:microsoft:sqlserver://csal1007:1433;DatabaseName=DBTEST"; 
          Connection dbCon = DriverManager.getConnection(url,"sa","");  
          File              fl    = new File("c:\\new.txt");
          FileInputStream   fis   = new FileInputStream( fl );
          PreparedStatement pstmt =
               dbCon.prepareStatement("INSERT INTO  ImageTable(ImgName, MyImage) VALUES (?, ?)");
          pstmt.setString( 1, "teste");
          pstmt.setBinaryStream(2,fis,(int)fl.length());
          pstmt.executeUpdate();
          pstmt.close();
          dbCon.close();
          fis.close();
       }catch(Exception e){ System.out.println("error " + e);}     
}Can any one of U look at this!!! ths should be easy I thought... I m sure lots of U have done something similar... so gimme a help

Hi there,
I use SQL Server 2000 and store binary data.
To do this I use the PreparedStatement method setBytes
So your code would go something like this:
public class ImageStream {
public static void main(String[] args) {
     ImageStream i = new ImageStream();
     i.put("ssfsf");
void put(String file){
try{
    Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver" );
    String url = "jdbc:microsoft:sqlserver://csal1007:1433;DatabaseName=BTEST";
    Connection dbCon = DriverManager.getConnection(url,"sa","");
    File              fl    = new File("c:\\new.txt");
    FileInputStream   fis   = new FileInputStream( fl );
    long length = fl.length();
    if (length > Integer.MAX_VALUE) {
            // File is too large
    // Create the byte array to hold the data
    byte[] bytes = new byte[ (int) length];
    // Read in the bytes
    int numRead = fis.read(bytes, 0, bytes.length);
    // Close the input stream and return bytes
    fis.close();
    PreparedStatement pstmt =  dbCon.prepareStatement("INSERT INTO  ImageTable(ImgName, MyImage)VALUES (?, ?)");
    pstmt.setString( 1, "teste");
    pstmt.setBytes(2,bytes);
    pstmt.executeUpdate();
    pstmt.close();
    dbCon.close();
    }catch(Exception e){ System.out.println("error " +  e);
