Get started with Java

Welcome to PDFTron. Java for the PDFTron SDK is supported on both Linux and Windows. To get started, choose your preferred platform from the tabs below.

Linux Java PDF library integration

This guide will help you run PDFTron samples and integrate a free trial of the PDFTron SDK into Java applications on Linux. Your free trial includes unlimited trial usage and support from solution engineers.

Prerequisites

  • JDK version ≥ 5
  • PDFTron SDK for Linux:

Run PDFTron SDK in production
A commercial license key is required for use in a production environment. Please fill out our licensing form if you do not have a valid license key.
Keep your commercial license key confidential.
License keys are uniquely generated. Please make sure that it is not publicly available (e.g. in your public GitHub).

Initial setup

  1. Extract the folder from the .zip file.
  2. Get your PDFTron trial key.

Run the samples

Run a specific sample

  1. Navigate to the JAVA folder in a sample project, for example /Samples/AddImageTest/JAVA and run the sample with
./RunTest.sh

Run all samples

  1. Navigate to /Samples and run
./runall_java.sh

The tests will run one by one.

Output files will be in /Samples/TestFiles/Output

Integrate into your application

This section will show you how to use our SDK to create a simple PDFTron "Hello World!" application. It will create a document with one blank page and save it as a linearized PDF in its running directory.

  1. Navigate to the /Samples directory of the PDFTron SDK and create a directory called myApp if it does not exist already. This guide will assume your project is named myApp.

  2. Enter your myApp directory and create a JAVA directory for organization. Then create a myApp.java file. Open this file in your favorite text editor and paste:

//@data {"ga":7331024761}// import java.io.File; import java.io.IOException;

import com.pdftron.common.PDFNetException;
import com.pdftron.pdf.*;
import com.pdftron.sdf.SDFDoc;
import com.pdftron.sdf.ObjSet;
import com.pdftron.sdf.Obj;

public class myApp
{
    public static void main(String[] args)
    {
        PDFNet.initialize();  // PDFNet must be initialized before accessing any PDFTron API
        try
        {
            PDFDoc doc = new PDFDoc();
            Page page = doc.pageCreate();  // Start a new page
            doc.pagePushBack(page);  // Add the page to the document
            doc.save("output.pdf", SDFDoc.SaveMode.LINEARIZED, null);  // Save the document as a linearized PDF
        }
        catch(PDFNetException e)
        {
            e.printStackTrace();
            System.out.println(e);
        }
        System.out.println("Hello World!");
    }
}
```
  1. Navigate back to your myApp project folder and compile your application using our PDFNet library:

//@data {"ga":2044133006}// javac -cp .:../../../Lib/PDFNet.jar myApp.java ```

  1. Run the project by executing:

//@data {"ga":1350016038}// java -Djava.library.path=../../../Lib -classpath .:../../../Lib/PDFNet.jar myApp ```

If all goes well, your terminal should output:

```

//@data {"ga":1866078370}// PDFNet is running in demo mode. Permission: write Hello World! ```

Check the output.pdf that the program output in the same directory. It should be a PDF with one blank page.
