Hi!

When use the JFreeChart sample in the iText book, it works fine as a
stand-alone app with a main method. However, I cannot get it to work
in a JavaBean. It seems the document does not close =
document.close().

Im using eclipse and tomcat seems to just hang.
org.apache.catalina.startup.Bootstrap window never closes, as it
usually does.

here is the code I tried with a servlet:

package mybeans;

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

import java.awt.Graphics2D;
import java.awt.geom.Rectangle2D;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;

import org.jfree.chart.ChartFactory;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.data.category.DefaultCategoryDataset;
import org.jfree.data.general.DefaultPieDataset;
import org.jfree.data.xy.XYSeries;
import org.jfree.data.xy.XYSeriesCollection;

import com.lowagie.text.Document;
import com.lowagie.text.DocumentException;
import com.lowagie.text.Rectangle;
import com.lowagie.text.pdf.DefaultFontMapper;
import com.lowagie.text.pdf.PdfContentByte;
import com.lowagie.text.pdf.PdfTemplate;
import com.lowagie.text.pdf.PdfWriter;

    int junior = reportBean.getJuniorCount();
    int senior = reportBean.getSeniorCount();
   
    //JFreeChart myChart = reportBean.getPieChart(freshman, sophomore,
junior, senior);
    reportBean.convertToPdf(getPieChart(freshman, sophomore, junior,
senior), 400, 500, "standing");
   
  }
 
  publicvoid convertToPdf(JFreeChart chart, int width, int height,
String filename) {
     
     // step 1
     Document document = new Document(new Rectangle(width, height));
     try {
       // step 2
       PdfWriter writer;
       writer = PdfWriter.getInstance(document, new FileOutputStream
(filename));
       System.out.println("getting writer");
       // step 3
       document.open();
       System.out.println("Document open");
       // step 4
       PdfContentByte cb = writer.getDirectContent();
       PdfTemplate tp = cb.createTemplate(width, height);
       Graphics2D g2d = tp.createGraphics(width, height, new
DefaultFontMapper());
       Rectangle2D r2d = new Rectangle2D.Double(0, 0, width, height);
       chart.draw(g2d, r2d);
       g2d.dispose();
       cb.addTemplate(tp, 0, 0);
       
     }
     catch(DocumentException de) {
       de.printStackTrace();
       
     }
     catch (FileNotFoundException e) {
       e.printStackTrace();
     }
     // step 5
     
     System.out.println("Closing document");
          document.close();
    }
