Create a PDF file using JAVA

Introduction

This weblog presents Java code to create a PDF file to be displayed in EP6 portal using AbstractPortalComponent.

I currently use this solution to convert all my reporting htmlb table display to PDFs.

I am going to use iText’s open source api to create a PDF file.

These apis can also be used to read PDF file. For more information about api check out the site. www.lowagie.com/iText/.

There is plenty of documentation and example code at this site.

Required Jars:

You can download the following iText jar from http://www.lowagie.com/iText/download.html.

servlet.jar, itext-1.2.jar

Steps to create PAR component

Step 1:

Create an AbstractPortalComponent using Eclipse or Netweaver Studio. Add the above jar (itext-1.2.jar) to PORTAL-INF->lib folder.

Step 2:

Add the following lines to doContent method.

public void doContent(  IPortalComponentRequest request,  IPortalComponentResponse response) {  try {   //create a document with certain page size   Document document = new Document(PageSize.A4);   HttpServletResponse res = request.getServletResponse(true);   //set the mimetype   res.setContentType(“application/pdf”);   PdfWriter.getInstance(document, res.getOutputStream());   //open the document for adding stuff   document.open();   //create a table with 3 columns   PdfPTable table = new PdfPTable(3);   PdfPCell cell;   //add the first row as header   cell = new PdfPCell(new Paragraph(“Rank”));   cell.setBackgroundColor(new Color(34, 90, 141));   table.addCell(cell);   cell = new PdfPCell(new Paragraph(“Name”));   cell.setBackgroundColor(new Color(34, 90, 141));   table.addCell(cell);   cell = new PdfPCell(new Paragraph(“Points”));   cell.setBackgroundColor(new Color(34, 90, 141));   table.addCell(cell);   //add the data rows.   int flag = 0;   Color bg;   for (int i = 0; i <= 10; i++) {    //alternate colors    if (flag == 0) {     flag = 1;     bg = new Color(204, 204, 255);    } else {     flag = 0;     bg = new Color(255, 255, 255);    }    cell = new PdfPCell(new Paragraph(“1”));    cell.setBackgroundColor(bg);    table.addCell(cell);    cell = new PdfPCell(new Paragraph(“Prakash Singh: ” + i));    cell.setBackgroundColor(bg);    table.addCell(cell);    cell = new PdfPCell(new Paragraph(“” + (50000 – i * 10) + “”));    cell.setBackgroundColor(bg);    table.addCell(cell);   }   document.add(table);   document.close();  } catch (Exception e) {  } }

Step 3:

Deploy it in portal and run it. You should get the following output.

And stored in c:\tomcat\webapps\irj\WEB-INF\lib\ext.

And refered in the project.
