<repositories>
   <repository>
      <id>repository.groupdocs.com</id>
      <name>GroupDocs Repository</name>
      <url>https://releases.groupdocs.com/conversion/java/</url>
   </repository>
</repositories>
<dependencies>
   <dependency>
      <groupId>com.groupdocs</groupId>
      <artifactId>groupdocs-conversion</artifactId>
      <version>25.2</version>
   </dependency>
</dependencies>

License Acquisition Steps

  1. Free Trial: Start by signing up for a free trial on the GroupDocs website to test features.
  2. Temporary License: Obtain a temporary license if you need more than what’s available in the trial version.
  3. Purchase: For long-term usage, consider purchasing a full license.

Basic Initialization and Setup

After setting up Maven dependencies, initialize the library with your license keys:

import com.groupdocs.conversion.License;

License license = new License();
license.setLicense("path/to/your/license.lic");

Implementation Guide: Setting Metered License

This section guides you through implementing a metered licensing feature using GroupDocs.Conversion for Java.

Overview of the Metered Feature

The metered license allows you to set usage limits, ensuring your application adheres to pre-defined operational constraints. This is particularly useful in subscription-based models where resource allocation needs precise control.

Step 1: Import Necessary Packages

Start by importing the necessary classes:

import com.groupdocs.conversion.licensing.Metered;

Step 2: Obtain License Keys

Obtain your public and private keys from the GroupDocs website or purchase portal. Replace placeholders with actual values.

String publicKey = "*****"; // Your public key here
String privateKey = "*****"; // Your private key here

Step 3: Create a Metered Object

Create an instance of Metered to manage your license configuration.

Metered metered = new Metered();

Step 4: Set the Metered License

Set the metered license using the keys obtained in the previous step:

metered.setMeteredKey(publicKey, privateKey);

Explanation: The setMeteredKey method initializes your licensing configuration with GroupDocs.Conversion, allowing you to track and control usage effectively.

Troubleshooting Tips

  • Incorrect Keys: Ensure that you have copied the keys correctly without any spaces.
  • Network Issues: Verify network connectivity if keys are fetched online.
  • Library Version Mismatch: Confirm that you’re using a compatible version of GroupDocs.Conversion.

Practical Applications

Understanding how to implement metered licenses can enhance your application in various ways:

  1. Subscription Management: Control usage for different subscription tiers.
  2. Resource Allocation: Optimize resource usage based on business needs.
  3. Cost Efficiency: Reduce costs by limiting API calls or document conversions.
