Answer 1

Hi,
my English, where is it? ;-)
I have a class with an attribute file, then I want to recover within the attribute file the content of the Blob field.
I am familiarized with Blob, but I do not give with the way to do.
I try this but the FileNotFoudException takes place
          BLOB blob = ((OracleResultSet)resultSet).getBLOB(i++);
          File manual = new File( "" ); // simply I want to have the file in memory, nothing but
          if (blob!=null) {
            InputStream blobStream = blob.getBinaryStream();
            FileOutputStream fileOutStream = new FileOutputStream( manual );
            byte[] buffer = new byte[10];
            int nbytes = 0;
            while ( ( nbytes = blobStream.read( buffer ) ) != -1 )
              fileOutStream.write( buffer, 0, nbytes );
            fileOutStream.flush();
            fileOutStream.close();
            blobStream.close();
          }
