Convert gif to byte array

[Keith Harrison]

Hello.

I have the following method:

    
  public static byte[] getPhoto (int iNumPhoto) throws Exception, SQLException{
 
try{
 

System.out.println("Photo ID=" + iNumPhoto);
conn = QueryToolDBConnection.getConnection();
conn.setAutoCommit (false);
Blob img ;
 
stmt = conn.createStatement ();
 
// Query
req = "Select image From Images Where ImageID = " + iNumPhoto ;
 
rset  = stmt.executeQuery ( req );
 
while (rset.next ())
{
  img = rset.getBlob(1);
  imgData = img.getBytes(1,(int)img.length());
}
 
} catch (SQLException exception){
System.out.println("ERROR in getPhoto(" + iNumPhoto + "): " +
"Error cause by query Statement.");
System.out.println(exception.toString());
System.out.println(req);
 
} finally {
try{
stmt.close();
conn.close();
 
}catch (SQLException ignored){}
}
 
System.out.println("imgData:" + imgData);
if(imgData == null){
 
>>>>>>>>>>>>>>>>>>>>>> HERE <<<<<<<<<<<<<<<<<<<<<<
 
}else{
return imgData ;
}
 
}

At the point where I have typed >>> HERE <<< I want to read in a gif image from localhost root directory (i.e "/images/noImage.gif") and convert it to a byte array to use as return.

Seems simple enough but need guidance!

Thanks to anybody who can help
