Implementation Guide

Setting License from File

Setting the license correctly is critical for accessing all features of GroupDocs.Annotation without limitations. Here’s how to implement this feature:

Overview

This section guides you through setting the GroupDocs.Annotation license using a file path, ensuring full library capabilities.

Step 1: Define License Path

Specify the path where your license file is located by defining a String variable:

// Define the path for your license file here.
String licensePath = "YOUR_DOCUMENT_DIRECTORY/License.lic";

Step 2: Create License Object

Create an instance of the License class from GroupDocs.Annotation to manage licensing operations:

import com.groupdocs.annotation.licenses.License;

// Initialize the License object
License license = new License();

Step 3: Set License Using File Path

Check if the license file exists and set it using the provided path:

import java.io.File;

// Check if the license file exists at the specified path
if (new File(licensePath).isFile()) {
    // Set the license using the file path
    license.setLicense(licensePath);

    // Verify if the license has been set successfully
    if (!License.isValidLicense()) {
        // Handle unsuccessful license setting (e.g., log an error)
        System.err.println("Failed to set license.");
    }
}

Explanation:

The setLicense() method specifies your license file path, ensuring the application can verify and use it.
Confirming the existence of the file before loading helps troubleshoot potential errors.

Troubleshooting Tips

File Path Issues: Ensure the license file path is correct and accessible from your code’s execution environment.
Invalid License: Verify that you have a valid license file. If using a temporary or trial license, ensure it hasn’t expired.
