License4J License Manager

License4J is a Java library designed for easy integration and use within Java applications. It offers a wide range of licensing features and supports floating licenses. The library can generate license text, floating license text, and license keys. License text can either be plain text or encrypted to conceal the content from customers. To generate serial numbers, users can input customer names, company names or use other methods. License4J also provides License Manager and Serial Number Manager GUI applications for generating and storing software license text and license keys.

The download package includes runtime library, development library, documentation, License Manager GUI tool, Hardware ID viewer application, and example applications. A free 10-day trial version is available for users to download and test License4J. However, this version limits license files to a 10-day expiration feature and disables some fields in serial numbers.

With the purchase of each License Manager, an Online.License4J account is created with a 1000 license limit. The Online.License4J system allows users to auto-generate licenses and activate them online through http posts. Overall, License4J is an excellent Java library for managing software licenses with a wide range of features and easy integration.
