PDF Generation in Java

PDF version of this tutorial is available HERE

Do you want to print something as a pdf in your java application? if, this text is for you. Its prety simple.
First you need download a jar. download it from here.
its 4.09MB in size.
now you need to configure it in your eclipse IDE. I use eclise. so no idea about others how to
configure. I hope you the other IDE users, know the best.

follow the steps-
1. Create a new java project in Eclipse named "Pdf Converter"
2. Right click on the Pdf Converter project in the package explorer view and select build path then
select Add libraries. there will pop up a box name add libraries. Select User library, press on the button at right top
side named "user library"
3. Click on New. Give a name of iText library and then Click ok.
4. now click on Add Jars button and browse the iText.jar in the directory.
5. Click OK.

Now you can use the classes of iText. The com.lowagie.text.Document is the main class for PDF document generation. First we need to instantiate it. Then we will write on it using the com.lowagie.text.pdf.PdfWriter class.

now lets see a example that print hello world as a pdf.

Code:


package iTextImpl;

import java.awt.Color;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import com.lowagie.text.Chunk;
import com.lowagie.text.Document;
import com.lowagie.text.DocumentException;
import com.lowagie.text.Font;
import com.lowagie.text.FontFactory;
import com.lowagie.text.PageSize;
import com.lowagie.text.Paragraph;
import com.lowagie.text.pdf.PdfContentByte;
import com.lowagie.text.pdf.PdfWriter;

public class HelloWorld {
   private static String text = "This is a simple tutorial on how to print your text"
         + "as a pdf.\n To print as pdf format you need to configure iText library.\n"
         + "This is a open source library.\n\n\n\n\n";

   public static void main(String[] args) {
      // document object created that describe the document attributes
      // like page size, margin etc
      Document document = new Document(PageSize.A4, 50, 50, 50, 50);
      try {
         // PdfWriter.getInstance() creates a PDF document writer that writes
         // PDF syntax to concerned file by a FileOutputStream.
         PdfWriter.getInstance(document, new FileOutputStream("hello.pdf"));
         document.open();

         document.addTitle("simple test pdf");

         document.add(new Paragraph(text, FontFactory.getFont(
               FontFactory.HELVETICA_OBLIQUE, 14, Font.NORMAL, new Color(
                     0, 150, 200))));

         // create a chunk object using chunk class of itext library.
         Chunk chunk = new Chunk("This is a simple pdf file created by: ");

         // set the distance between text and line.
         chunk.setTextRise(10.0f);
         chunk.setUnderline(new Color(10, 160, 10), 0, (float) 0.2, 3, 0,
               PdfContentByte.LINE_CAP_PROJECTING_SQUARE);

         document.add(chunk);

         document.add(new Paragraph("Bazlur Rahman", FontFactory.getFont(
               FontFactory.COURIER, 16, Font.BOLD,
               new Color(100, 150, 100))));

         document.close();

      } catch (FileNotFoundException e) {
         e.printStackTrace();
      } catch (DocumentException e) {
         e.printStackTrace();
      }

   }
}

tui ei post ta na dile toke call kortam eita janar jonno. call korte hoilo na..

Hey I've written an api with this itext. All about this will be available here

Well from what I've found out, if you are looking for a document generation system on Java, take a look at this Java document generation site. It has basic info on all the vendors. It makes for a great starting point.
