Hi,
I have just read your post, and did a Google search, and will below provide some useful resources for you to read, and learn from, I have also provided URL's to a video website where you can learn Java from "novice" to "intermediate" java programming.
All you need is; Time, and Dedication.

2. Learning Java (Intermediate, Video Tutorials)

3. The Java Web Services Tutorial

I hope this has helped you, I'm also revising my current "Java" knowledge so if you require specific help with functions, etc. Feel free to PM me, I will respond once I have "earned" the ability to send PM's after I've made 30 Quality Posts.
Regards,
