I am using a servlet that retrieves the BLOB from the database, sets the MIME type and puts it in a stream. The code is :
package TestQueryITM;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import java.net.*;
import java.sql.*;
import oracle.sql.*;
import oracle.jdbc.driver.OracleDriver;
import oracle.jdbc.driver.*;
public class MIMEServlet extends HttpServlet {
DbConnect myDbBean = new DbConnect();
int Id=6;
String MIME ="plain/text";
public void init(ServletConfig config) throws ServletException
super.init(config);
public void doGet(HttpServletRequest req,HttpServletResponse res)
throws ServletException, IOException
try
String content_type = new String();
String filename = new String();
// Load the Oracle JDBC driver:
Class.forName("oracle.jdbc.driver.OracleDriver");
// Connect to the database:
Connection conn = DriverManager.getConnection
("jdbc:oracle:thin:@ORAVISION:1521:DEV","[username]", "[password]");
// It's faster when auto commit is off:
conn.setAutoCommit (false);
// Create a Statement:
Statement stmt = conn.createStatement ();
try
BLOB lob_loc = null;
java.io.InputStream in = null;
int pos = 0;
int length = 0;
OracleResultSet rset = (OracleResultSet) stmt.executeQuery (
"SELECT text FROM test WHERE ID = "+Id);
if (rset.next())
lob_loc = ((OracleResultSet)rset).getBLOB(1);
MIME=rset.getString(2);
// File binaryFile = new File("C:/aantekeningen.doc");
// FileInputStream in = new FileInputStream(binaryFile);
in = lob_loc.getBinaryStream();
// This loop fills the buf iteratively, retrieving data // from the InputStream:
res.setContentType (application/pdf);
res.setHeader ("Content-Disposition","attachement;filename=test.doc");
ServletOutputStream op = res.getOutputStream ();
byte[] buffer = new byte[32000];
while ((in != null) && ((length = in.read(buffer)) != -1))
// the data has already been read into buf
System.out.println("Bytes read in: " +
Integer.toString(length));
op.write(buffer,0,length);
op.flush();
op.close ();
in.close();
stmt.close();
conn.commit();
conn.close();
}catch (SQLException e)
e.printStackTrace();
}catch(Exception e)
System.out.println("<BR>");
e.printStackTrace();
System.out.println("<BR>");
public String getServletInfo() {
return "TestQueryITM.MIMEServlet Information";
null
