Answer 1

the mySql blob class has the following function : blob.getBytes use it like this: //(assuming you have a ResultSet named RS) Blob blob = rs.getBlob("SomeDatabaseField"); int blobLength = (int) blob.length(); byte[] blobAsBytes = blob.getBytes(1, blobLength); //release the blob and free up memory. (since JDBC 4.0) blob.free();
