Let’s begin by covering the prerequisites before diving into the actual setup.

Prerequisites

Before implementing this feature, ensure you have the following:

Required Libraries and Dependencies

Include GroupDocs.Parser for Java in your project via Maven or direct download.

  • Maven Dependency:
    <repositories>
   <repository>
      <id>repository.groupdocs.com</id>
      <name>GroupDocs Repository</name>
      <url>https://releases.groupdocs.com/parser/java/</url>
   </repository>
</repositories>

<dependencies>
   <dependency>
      <groupId>com.groupdocs</groupId>
      <artifactId>groupdocs-parser</artifactId>
      <version>25.5</version>
   </dependency>
</dependencies>
  • Direct Download: Access the latest version from GroupDocs.Parser for Java releases.

Environment Setup

Ensure your development environment includes:

  • JDK (Java Development Kit) version 8 or higher
  • An IDE like IntelliJ IDEA, Eclipse, or NetBeans

Knowledge Prerequisites

Familiarity with Java programming and basic file handling in Java will be beneficial.

Setting Up GroupDocs.Parser for Java

With prerequisites met, proceed to set up the library by adding dependencies and acquiring a license.

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 acquiring your license file, place it in a directory within your project.

Basic Initialization

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

Implementation Guide: Setting License from File

This section focuses on implementing the feature using Java code snippets and detailed explanations.

Overview of Feature

Setting a license from a file allows your application to utilize GroupDocs.Parser’s features without restrictions. This 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.
