Implementation Guide

This section focuses on setting the license from a file using GroupDocs.Search for Java. The steps are divided logically to simplify the implementation process.

Feature Overview: Setting License from File

This feature allows your application to automatically apply a license if it exists in the specified directory, ensuring full functionality without interruptions due to licensing issues.

Step-by-Step Implementation

Step 1: Import Required Packages

Start by importing necessary packages:

import com.groupdocs.search.licenses.License;
import java.nio.file.Files;
import java.nio.file.Paths;

These imports are crucial for file handling and setting the license.

Step 2: Define License Path

Specify the path to your license file:

String licensePath = "YOUR_DOCUMENT_DIRECTORY/license.lic";

Step 3: Check if License File Exists

Ensure the specified license file exists before attempting to set it:

if (Files.exists(Paths.get(licensePath))) {
    License license = new License();

    // Step 4: Set the License Using the Specified File
    license.setLicense(licensePath);
    
    // License is successfully applied at this point.
}

Explanation of Key Steps:

  • Files.exists: Checks the existence of the file, preventing runtime errors.
  • setLicense: Applies the license to your application.

Troubleshooting Tips

  1. File Path Issues: Ensure the path is correct and accessible by your Java application.
