How to resolve ORA-01460 Error? - oracle

Question

I am uploading photos to oracle database.The code for my AddPhotoServlet class is as follows.
import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.util.List;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
public class AddPhotoServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try {
// Apache Commons-Fileupload library classes
DiskFileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload sfu = new ServletFileUpload(factory);
/*if (! ServletFileUpload.isMultipartContent(request)) {
System.out.println("sorry. No file uploaded");
return;
}*/
// parse request
List items = sfu.parseRequest(request);
FileItem id = (FileItem) items.get(0);
String photoid = id.getString();
FileItem title = (FileItem) items.get(1);
String phototitle = title.getString();
// get uploaded file
FileItem file = (FileItem) items.get(2);
// Connect to Oracle
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection con =DriverManager.getConnection("jdbc:oracle:thin:#localhost:1521:xe", "cloud", "cloud");
con.setAutoCommit(false);
PreparedStatement ps = con.prepareStatement("insert into photos values(?,?,?)");
ps.setString(1, photoid);
ps.setString(2, phototitle);
// size must be converted to int otherwise it results in error
ps.setBinaryStream(3, file.getInputStream(), (int) file.getSize());
ps.executeUpdate();
con.commit();
con.close();
out.println("Proto Added Successfully. <p> <a href='listphotos'>List Photos </a>");
}
When i run the html page in the server while uploading it throws the error :
ORA-01460:unimplemented or unreasonable conversion requested.
Can anyone please help me with this ?
I have created my table as :
create table photos
(
id number(5) primary key,
title varchar2(50),
photo blob
);

Check out the oracle jdbc developer's guide for working with streams and lobs. There are quite a few options on how the data is handled that has different performance/memory implications.
One portion of the second doc (on lobs) covers the use of temporary lob objects by using Connection.createBlob() and writing the content to that object and then setting that blob object on the statement.
