Inserting data into oracle BLOB through JDBC

Hi all,
I am trying to insert data into oracle BLOB through JDBC. I am able to insert the data using oracle.sql.BLOB which have methods like putBytes() and setBytes().

I have two concerns:
First one: I am inserting the data using the following code

ps = conn.prepareStatement(sql);
oracle.sql.BLOB newBlob = oracle.sql.BLOB.createTemporary(conn,false, oracle.sql.BLOB.DURATION_SESSION);


sql statement contains one ? (i.e. bind variable), and docout is a stringBuffer which contains desired length of user (ex: 40,000).

Question: Is this the right way to insert blob data through JDBC or is there is any other better way? actually I want to insert Word documents into BLOB.
Second One: I have experimented this code with Oracle 9i JDBC and Oracle 10g JDBC.
Oracle 9i: In Oracle 9i jdbc driver putBytes() method is working, setBytes() is not working (error: unsupported feature).
Oracle 10g: In Oracle 10g jdbc driver putBytes() is working but it says putBytes is a deprecated method, setBytes() is working properly.

We still did not tested with Oracle 8i.

My concern is I have to write a program which can be used with any version of Oracle JDBC like 8i, 9i or 10g where I can use a single method

Oracle publishes a complete working example program for BLOBs and CLOBs, the "LOB Datatype" example, here:
I agree. Here's the link:
