Is this a column of type ORDImage or a column of some other type? I am not sure what you mean by ordImagedomain column.
In either case, reading the values from the database into the Java program and updating the other database with those values would be one way to do this. ORDImage is an object type and has a BLOB attribute so the select statement should be written accordingly. Chapter 5 in the Oracle Multimedia User's Guide has some examples.
