Blob interface problem

Question

hi all,
im facing an stylist problem when inserting blob into oracle dbms. im trying in a very simple way like this :
stmt.executeUpdate("insert into picture values('sample1.gif',empty_blob())");
ResultSet rs= stmt.executeQuery("select * from picture where name='sample1.gif' for update");
          rs.next();
          oracle.sql.BLOB blob=(oracle.sql.BLOB)rs.getBlob(2);
          FileInputStream in= new FileInputStream(filename);
          OutputStream os=blob.getBinaryOutputStream();
          int data;
          while((data=in.read())!=-1){
                         os.write(data);
     in.close();
     os.close();
this code is ok but i have an allergy about standerizing my coding so im trying to use the following code :
stmt.executeUpdate("insert into picture values('sample1.gif',empty_blob())");
ResultSet rs= stmt.executeQuery("select * from picture where name='sample1.gif' for update");
          rs.next();
          java.sql.Blob blob=rs.getBlob(2);
          FileInputStream in= new FileInputStream(filename);
          OutputStream os=blob.setBinaryStream(1);
          int data;
          while((data=in.read())!=-1){
                         os.write(data);
     in.close();
     os.close();
but the problem is setBinaryStream(int pos) is not implemented by oracle.sql.BLOB class. my oracle version is 9.0.1.0.1. when i run it,it shows an exception like abtract method error. is there any way not to use the oracle.sql.BLOB for inserting blob into oracle database ?

I can't give a definitive answer but I've observed the same problem.
The ability to get an outputstream to a Clob was only introduced in JDBC 3.0.
Chapter 5 of Oracle's JDBC Developer's Guide and Reference http://download-west.oracle.com/docs/cd/B10501_01/java.920/a96654/jdbc30ov.htm#1004903 mentions that only some JDBC 3.0 features are implemented; none of the mentioned features include the API calls for streaming to a Clob.
