Linux Java PDF library integration

This section will show you how to use our SDK to create a simple Apryse "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 Apryse 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:

   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 Apryse 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!");
       }
   }

3. Navigate back to your myApp project folder and compile your application using our PDFNet library:

   javac -cp .:../../../Lib/PDFNet.jar myApp.java

4. Run the project by executing:

   java -Djava.library.path=../../../Lib -classpath .:../../../Lib/PDFNet.jar myApp

   If all goes well, your terminal should output:

   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.
