    *"java code to view pdf file on browser without downloading them."* This is impossible. A browser ***must*** download a file in order to display it! BTW - 1) Words typed in all lower case are hard to read, like trying to listen to someone who is mumbling. Please use an upper case letter at the start of sentences, for the word I, and proper names like `ArrayList` or Oracle. 2) This had the [tag:eclipse] tag added and none other. This has **nothing** to do with your IDE and everything to do with Java and PDF (for which tags are now added). – Andrew Thompson Mar 07 '15 at 10:43

You need to use a servlet to do that:

import java.io.IOException;
import java.io.*;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.sql.*;

public class viewPDF extends HttpServlet {

    public void doGet(HttpServletRequest request, 
            HttpServletResponse response)
    throws ServletException, IOException {
        OutputStream out = null;
        DB1 db = new DB1();
        Connection conn=db.dbConnect(
                "jdbc:jtds:sqlserver://localhost:1433/smpp","sa","");

        try {

            response.setContentType("application/pdf");
            out = response.getOutputStream();
            byte[] b = db.getPDFData(conn);
            out.write(b,0,b.length);
            out.close();
        } catch (Exception e) {
            throw new ServletException(
                    "Exception in Excel Sample Servlet", e);
        } finally {
            if (out != null)
                out.close();
        }
    }

    public void doPost(HttpServletRequest request,
            HttpServletResponse response)
            throws IOException, ServletException {
        doGet(request, response);
    }
}
