Setting maximum packet size in JDBC driver to send data to database

Question

Could someone tell me how I can set the JDBC connection property of maximum packet size to send data to database?

Hi thanks....I'm having this strange SQLException while trying to insert BLOB image data to Oracle database. I'm saying this strange because for the same image that has been inserted before it's throwing the exception. My program is run from Oracle form and then some image data are inserted into database through a loop. I can't realize what's the problem inside my code that's causing this problem. In fact, when I run my program independently not from Oracle Form, it runs fine, every image data get inserted into database. Given below is my code snippet:
public void insertAccDocs(String[] accessions) throws SQLException
    for(int q=0; q<accessions.length; q++)
    final String  docName = accessions[q];
    dbThread = new Thread(new Runnable(){
    public void run()
      try{
      System.out.println("insertDB before connection");
               getConnected();
               System.out.println("insertDB after connection");
               st=con.createStatement();
         //String docName = acc; commented
     // String docName = singleAccession;
               String text = formatFree;
               String qry = "INSERT INTO DOCUMENT VALUES
('"+docName+"','"+text+"','"+formatted+"','"+uiid+"')";
               System.out.println("parentqry"+qry);
               int ok=0;
               ok=st.executeUpdate(qry);
               if(ok==1)
            System.out.println("INSERTION SUCCESS= "+ok);
                    System.out.println("Image List Size"+ imgList.size());
            // inserting into child
                    for(int i=0;i<imgList.size(); i++)
                  String imgPath = ""+imgList.get(i);
                              System.out.println("db"+imgPath);
                              FileInputStream fin = new FileInputStream(imgPath);
                              BufferedInputStream bufStr = new BufferedInputStream(fin);
                              byte[] imgByte = new byte[bufStr.available()];
                              String img = "" + imgNameList.get(i);
                              System.out.println("imgid="+i);
            callable = con.prepareCall("{call prc_insert_docimage(?,?,?)}");
            callable.setString(1,docName);
                        callable.setString(2,img);
            callable.setBinaryStream(3, bufStr , (int)imgByte.length);
            callable.execute();
        callable.close();
                 con.commit();
        con.close();
               else
                    System.out.println("INSERTION NOT SUCCESS");
   //   } //else end of severalAcc
               }catch(Exception err){ //try
                    System.out.println(err.toString());
    } //run
  }); //runnable
  dbThread.start();     
}And the exception thrown is :
java.sql.SQLException: Data size bigger than max size for this type: #####
Please let me know if possible how I can get around this.
