Check out the PreparedStatement API. In particular look at setBinaryStream(), setUnicodeStream(), and setAsciiStream() which can be used to convert a stream to a blob during an insert/update statement.

Azhar,
You can create a ByteArrayInputStream from your byte[] and use that.

To create a Blob directly, you would have to write database specific code - something that should be avoided without a good reason.
