How to Set GroupDocs License in Java

With the prerequisites out of the way, let’s dive into the actual licensing steps.

Acquiring a License

GroupDocs offers different types of licenses:

  • Free Trial: Test out basic features.
  • Temporary License: Obtain from here for full access during development.
  • Purchase: For long‑term, commercial use.

After you receive your license file, place it in a directory that is part of your project (for example, src/main/resources).

Basic Initialization

Make sure GroupDocs.Parser is added to your project dependencies. Next, integrate license handling into your application code.

Implementation Guide: Setting License from File

This section provides the exact code you need, along with detailed explanations.

Overview of Feature

Setting a license from a file allows your application to utilize GroupDocs.Parser’s features without restrictions. The process involves checking if the license file exists, initializing it, and applying it to your application.

Step 1: Prepare Your License File Path

Define the path where your license file is stored:

String licensePath = "YOUR_DOCUMENT_DIRECTORY/GroupDocs.license";

Replace "YOUR_DOCUMENT_DIRECTORY" with the actual directory containing your GroupDocs license file.

Step 2: Check for License File Existence

Confirm the file exists to avoid runtime errors:

File licenseFile = new File(licensePath);
if (licenseFile.exists()) {
    // Proceed to set the license
}

Step 3: Instantiate and Set the License

If the file is present, create a License object and apply your license:

import com.groupdocs.parser.licensing.License;

public class SetLicenseFromFile {
    public static void run() {
        if (licenseFile.exists()) {
            License license = new License();
            license.setLicense(licenseFile.getPath());
            System.out.println("License set successfully.");
        } else {
            System.out.println("We do not ship any license with this example. \
                    Visit the GroupDocs site to obtain either a temporary or permanent license. \
                    Learn more about licensing at https://purchase.groupdocs.com/faqs/licensing. \
                    Learn how to request a temporary license at https://purchase.groupdocs.com/temporary-license.");
        }
    }
}

This code snippet ensures your application runs with full access by applying the license using setLicense.

Troubleshooting Tips

  • Verify that the path you provide is correct and the file is readable by the application.
  • Make sure the GroupDocs.Parser version you use is compatible with your JDK.
  • If you encounter licensing errors, consult the official support forum at GroupDocs support.
