The latest release of the library is Apache PDFBox 3.0.0-RC1. It allows us to create PDFs, read, and manipulate PDFs. It includes several command-line utilities. It is an open-source library that can be used while dealing with PDF documents. So, in this section, we will discuss only Apache PDFBox, iText, and PDF Clown library.

The first two libraries are more popular and widely used by developers. There are various libraries that can be used to create a PDF file using a Java program.

What if we want to create a PDF file in Java using the Java program? In this section, we are going to learn how to create PDF using a Java program. Using the POI Library, we can easily create DOC, DOCX, XLS, XLSX, PPT, and PPTX files. It is an API that deals with Microsoft Office Documents. Import .In the previous sections, we have learned about Apache POI Library. Consider following simple Struts Action class which uses this mechanism to generate a dummy PDF and sent the output to browser. Hence the PDF should be generated on fly and sent to client browser. Generate PDF as Output Stream in HTTP request Sometime we may want to add the PDF generation functionality to a web application, where user on clicking some link or button is served with PDF output. Thus in our case we have created a output file and sent output to it. Also, by supplying OutputStream object to getInstance() method sends the output to OutputStream.

OutputStream file = new FileOutputStream( new File( "D:\\Test.pdf")) ĭocument.add( new Paragraph( "Hello World, iText")) ĭocument.add( new Paragraph( new Date().toString())) Ĭode language: Java ( java )In above code snippet we have created Document object which represents our PDF document. After you execute this, a file Test.pdf will be created in C: drive (If you are using Linux, you may want to have /usr/test.pdf as path). All you have to do is to put itext.jar in your class path and paste following code in GeneratePDF.java class and compile and execute it.

Getting iText Download iText jar from its home page iText core: iText-5.2.1.jar Generate simple PDF in Java using free Java-PDF library It is very easy to generate a simple PDF file in Java using iText.

Split, concatenate, and manipulate PDF pages.

Add bookmarks, page numbers, watermarks, etc.

Generate dynamic documents from XML files or databases.

Rather, you’ll build iText into your own applications so that you can automate the PDF creation and manipulation process. Typically you won’t use it on your Desktop as you would use Acrobat or any other PDF application. iText is an ideal library for developers looking to enhance web- and other applications with dynamic PDF document generation and/or manipulation. iText is a free Java-PDF library that allows you to generate PDF files on the fly ( dynamically). Doing this with Java is not an easy task as Java does not gives default api’s to handle PDF files. Generating PDF files in today’s enterprise applications is quite common.
