ServletLM

ServletLM is a small 100% Java license manager extension that enables protection for per-context and per-instance licensing in standalone and J2EE applications. ServletLM is a Java package that as far as possible allows only as many application instances to run as there are license keys. It will not allow the same key to be used multiple times on the same machine unless specified. This has always been difficult for Java applications to enforce. Works across multiple VM's and Web server contexts. Simple to integrate into your application. Works with almost any third party license manager. Works with most license protection software.
