copy protection / IP protection

Hello,

I need to build a WAR/JAR that will need to fulfil the following requirements:

1. The code will only work for a trial period (30 days)

2. The code can be unlocked with a key

3. Unlocking the code will watermark the WAR/JAR with a unique key

I do not want to reinvent the wheel and would love to hear from other folks that have experience with this type of packaging. Are there any off-the-shelf solutions?

Cheers,

Godfrey Hobbs
