[Openswan Users] Should I take a course in Java? Need advice

[Kay Obermueller]

Hello everyone,
I'm happily using OpenNMS and I have the chance now to get a course on 
programming in Java. It's an alternative to a PHP based course for web 
developing.
Do you tink it is advisable to learn Java to use OpenNMS, promote it and get 
customers for my services? Is it a realistic idea to get involved in the 
OpenNMS project so that it would help me to find customers?
