How to Update Form Fields from PDF Document using Cloud Java SDK

In order to update an AcroForm via Cloud Java SDK , we’ll use Aspose.PDF Cloud Java SDK This Cloud SDK allows you to easily build cloud-based PDF creator, editor & converter apps in Java language for various cloud platforms. Open Repository package manager, search for Aspose.PDF Cloud and install. You may also use the following command from the Package Manager Console for install it using Maven.

Add Aspose Cloud repository to your application pom.xml

Add Aspose Cloud repository


    <repositories>
        <repository>
            <id>aspose-cloud</id>
            <name>Aspose Cloud Repository</name>
            <url>https://releases.aspose.cloud/java/repo/</url>
        </repository>
    </repositories>

To install the API client library to your local Maven repository, simply execute:

Installation from Github


    mvn clean install

To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:

Deploy Maven repository


    mvn clean deploy

This sample code shows updating the AcroForms in PDF documents


    package com.aspose.asposecloudpdfusecases.acroforms;

    import java.io.File;
    import java.nio.file.Path;
    import java.nio.file.StandardCopyOption;
    import java.util.ArrayList;

    import com.aspose.asposecloudpdf.model.Fields;
    import com.aspose.asposecloudpdf.model.FieldsResponse;

    public class AcroformsChangeFileds {
        public static void update() {
            String REMOTE_FOLDER   = "Your_Temp_Pdf_Cloud";
	    String LOCAL_FOLDER    = "c:\\Samples";
	    String PDF_DOCUMENT    = "sample.pdf";
            String PDF_OUTPUT      = "forms_set_output.pdf";

            try {
                PdfApi pdfApi = new PdfApi(API_KEY, API_SECRET);

                // upload local PDF file to remote storage
                File file = new File(Path.of(LOCAL_FOLDER, PDF_DOCUMENT).toString());
                pdfApi.uploadFile(Path.of(REMOTE_FOLDER , PDF_DOCUMENT).toString(), file, null);
                System.out.println(String.format("File '%s' successfully uploaded!", Path.of(LOCAL_FOLDER, PDF_DOCUMENT).toString()));

                com.aspose.asposecloudpdf.model.Field field = new com.aspose.asposecloudpdf.model.Field();
                field.name("Siganture_1");
                field.type(com.aspose.asposecloudpdf.model.FieldType.TEXT);
                field.values(new ArrayList<String>(){{ add("aspose-pdf-cloud@example.com"); }});

                ArrayList<Field> fieldsList = new ArrayList<Field>();
                fieldsList.add(field);
                Fields fields = new Fields().list(fieldsList);

                FieldsResponse response = pdfApi.putUpdateFields(PDF_DOCUMENT, fields, null, REMOTE_FOLDER);
                if (response.getCode() != 200)
                    System.err.println("Error: unexpected error when updating field! '" + response.getStatus() + "'");
                else{
                    // download changed PDF file from remote folder...
                    File f = pdfApi.downloadFile(Path.of(REMOTE_FOLDER , PDF_DOCUMENT).toString(), null, null);
                    java.nio.file.Files.copy(Path.of(f.getPath()), Path.of(LOCAL_FOLDER, PDF_OUTPUT), StandardCopyOption.REPLACE_EXISTING);
                    System.out.println(String.format("File '%s' successfully dowloaded!", Path.of(LOCAL_FOLDER, PDF_OUTPUT).toString()));                
                    System.out.println("Successfully updated field in document ! '" + PDF_OUTPUT + "'");
                }
            }
            catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
 

Work with the AcroForms via Java SDK

AcroForms allows users to interact directly with the PDF by filling out fields, selecting options, or clicking buttons, making the document more dynamic. Interactive forms enable efficient data collection, reducing the need for manual data entry or external tools. This is ideal for surveys, registrations, and application processes. Users can fill in forms electronically without printing, scanning, or using other tools, saving time and effort. Including AcroForms in documents creates a polished and modern presentation, reflecting professionalism and attention to detail. Add the AcroForms into PDF documents with Aspose.PDF Cloud Java SDK.
