File upload into database using Hibernate

[liljejalil]

Hello all,

Can anyone please help..

I am designing a webapplication in java. I have set up forms and sucessfully upload data into mysql database. I now want to upload a file.

i have created my class..

import java.io.Serializable;
import java.sql.Blob;

public class User implements Serializable {

    private Long userId;
  
    private Blob upfile;

	public Long getUserId() {
		return userId;
	}

	public void setUserId(Long userId) {
		this.userId = userId;
	}

	public Blob getUpfile() {
		return upfile;
	}

	public void setUpfile(Blob upfile) {
		this.upfile = upfile;
	}

   
}

and my jsp.page

<form name="upform" enctype="multipart/form-data" action="servlet/building?action=UpLoadFile" method="POST">
        Name:<input type="file"/><br>
        <input type="submit" value="Upload"/>
    </form>

i have also done the user.hbm.xml as

<class name="com.attainware.maven2example.model.User"
		table="users">

		<id name="userId" column="USERID">
			<generator class="native" />
		</id>

		
		<property name="upfile" type="blob" column="USER_FILEBIN"/>
	</class>

The problem i have is i dont know what my action class would be like..
for normal upload i ise somethin like...

public void processRequest(HttpServletRequest request,
			HttpServletResponse response) throws ServletException, IOException {
		String id = (String) request.getParameter("id");
user = new User();
user.setId(id);
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
		Transaction tx = session.beginTransaction();
		session.save(user);
		tx.commit();

the question is how do i do this action for a file. so it stores it in the database.

Thank you for your help in advance..
