Answer 1

i saw a bit code about this convertions,
//one side
ResultSet r = ...........
BLOB b = (BLOB)r.getBlob('ICON');//BLOB is oracle type not Blob
byte[] base = b.getBytes();
Strgin res = Base64.encode(base);
//other side
String dec = datos;// data in base64
byte[] base = Base64.decode(dec.getBytes());
BLOB b = null;
b.setBytes(base);
is this code correct????
i tried to test but a have an error with
public static void BLOBToFile(BLOB datos,String path)
try
FileOutputStream fos=new FileOutputStream(path);
byte[] tempBin=new byte[8];
long cant=1;
while (cant <= datos.length())
tempBin=datos.getBytes(cant,Integer.MAX_VALUE);
cant = Integer.MAX_VALUE+1;
fos.write(tempBin);
fos.close();
catch(Exception e)
e.printStackTrace();
and the error is outOfMemory
how can i test my code??
