How to create and fill out your own PDF form with Java


In this tutorial, you will learn how to populate a PDF document with Java using the PDFBox library. In addition you will see how to create your own forms or add editable fields to an existing PDF document.

Creating a simple form

To create a form, let's use LibreOffice Draw.

Display the form toolbar. View Menu > Toolbars > Form Controls.

In a blank document, enter two text fields:

Display the properties of the text field:

Rename the fields to 'txt_1' and 'txt_2' respectively. Also leave the 'Read-only' property as 'Yes'.

Export the document as PDF. Mine is like '/tmp/pdf-java.pdf'

My template looked like this:

Populating the PDF through Java

Create a new maven Java project and add the dependency below:


Create a Java class with the code below:

    public static void main(String[] args) {
        try {
            PDDocument pDDocument = PDDocument.load(new File("/tmp/pdf-java.pdf"));
            PDAcroForm pDAcroForm = pDDocument.getDocumentCatalog().getAcroForm();
            PDField field = pDAcroForm.getField("txt_1");
            field.setValue("This is a first field printed by Java");
            field = pDAcroForm.getField("txt_2");
            field.setValue("This is a second field printed by Java");
        } catch (IOException e) {

Run the program and see the result:

Remember, the ending file was saved to: "/tmp/pdf-java-output.pdf".

The complete source code it's on github:


In this short tutorial, we learned how to populate a PDF from a PDF template created with LibreOffice Draw. Use your creativity to create beautiful templates, do automation, create batch files and more.
