[google-appengine] How to insert image into pdf ?

[suersh babu]

Hi,

I am using pdfjet, when I try to insert image I am getting this Error:

[ERROR] java.io.IOException: Stream closed
[ERROR] java.io.IOException: Stream closed

And this is my servlet code:
/**
 *
 */
package com.veersoft.accounting.servlet;

import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.util.logging.Logger;

import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.pdfjet.A4;
import com.pdfjet.Font;
import com.pdfjet.Image;
import com.pdfjet.ImageType;
import com.pdfjet.PDF;
import com.pdfjet.Page;
import com.pdfjet.RGB;
import com.pdfjet.TextLine;

public class PDFServlet extends HttpServlet {

......
    public void doPost(HttpServletRequest req, HttpServletResponse res)
            throws ServletException, IOException {
    }

    public void doGet(HttpServletRequest req, HttpServletResponse res)
            throws ServletException, IOException {
        OutputStream out = res.getOutputStream();
        try {
            res.setStatus(HttpServletResponse.SC_OK);
            res.setHeader("Content-Disposition", "attachment;");
            res.setContentType("application/pdf");

            OutputStream os = res.getOutputStream();
            this.example(os);

            os.flush();
            os.close();
        } catch (Exception e) {
            LOG.severe(e.toString());
        } finally {
            out.close();
        }
    }

    public void example(
            OutputStream os) throws Exception {
        ClassLoader cl = PDFServlet.class.getClassLoader();
        PDF pdf = new PDF(os);

        pdf.setTitle("Using TextLine class");
        pdf.setSubject("Examples");
        pdf.setAuthor("WebWineWatch");

        Font f1 = new Font(pdf, "Helvetica");
        Font f2 = new Font(pdf, "Helvetica");

        Page page = new Page(pdf, A4.PORTRAIT);
        f1.setSize(24);
        f2.setSize(12);

        Image image;
        String fileName = "../images/intro-3.jpg";
        try {
            BufferedInputStream bis1 =
                new BufferedInputStream(
                        getClass().getResourceAsStream(fileName));
            image = new Image(pdf, bis1, ImageType.JPEG);

        } catch (Exception e) {
            LOG.severe(e.toString());
            image = null;
        }
        if (image != null) {
            image.setPosition(0, 200);
            image.scaleBy(0.5);
            image.drawOn(page);
        }
        Image image2;
        try {
            BufferedInputStream bis2 =
                new BufferedInputStream(
                        getClass().getResourceAsStream(fileName));
            image2 = new Image(pdf, bis2, ImageType.JPEG);
        } catch (Exception e) {
            LOG.severe(e.toString());
            image2 = null;
        }
        if (image2 != null) {
            image2.setPosition(100, 100);
            image2.scaleBy(0.5);
            image2.drawOn(page);
        }

        TextLine text1 = new TextLine(f1);
        text1.setColor(RGB.BLACK);
        text1.setText("Veersoft WebWineWatch");
        text1.setPosition(250, 160);
        text1.drawOn(page);

        TextLine text2 = new TextLine(f2);
        text2.setColor(RGB.BLUE);
        text2.setText("Hello AccountingGuru.in!");
        text2.setPosition(250, 350);
        text2.drawOn(page);
        pdf.flush();
        os.close();
    }
}

Any suggestion much appreciated.
