How do you set a GroupDocs license in Java?

License is the SDK class that loads a GroupDocs license file and activates full‑feature mode for the JVM. Load your license file with the License class and call setLicense before any conversion call – that single step activates full‑feature mode for the entire JVM session. Example: new License().setLicense("groupdocs-license.xml"); This eliminates trial watermarks, disables internal throttling, and grants access to premium formats immediately.

What are the different ways to set GroupDocs license in Java?

GroupDocs.Conversion offers three common approaches to apply a license in Java applications. You can load the license from an InputStream for cloud‑based deployments, use a file‑path when the license file resides on disk, or configure metered licensing to track usage per document in SaaS scenarios. Choose the method that matches your deployment model.

  1. InputStream method – ideal for cloud deployments where the license is embedded as a resource.
  2. Metered licensing – lets you track usage per document, perfect for SaaS billing.
  3. File‑path method – straightforward for on‑premises apps that store the license on disk.

A: The SDK runs in trial mode, adds watermarks to output files, and may limit the number of pages processed per document.

A: It does; you can configure a usage limit or quota programmatically, and the SDK will enforce it regardless of deployment type.

A: GroupDocs.Conversion supports Java 8 and newer, including Java 11, 17, and the latest LTS releases.
