I am starting to learn web-services in java EE6.

I did web development before, but never nothing related to web services.

All is new to me and the books and the tutorials i find in the web are to technical.

I started learning about .xsd schemas and also .xml.

In that topic i feel confident, i understand what are the schemas used for and what validation means.

Now my next step is learning about JAX-B(Java Api for XML Binding). I rode some about it and i did also some practice in my IDE. But i have lots of basic doubts, that make me stuck and cannot feel confident to continue to the next topic.

Ill appreciate a lot if someone could explain me well my doubts:

1. What does it mean mapping and what is a mapping tool?
2. What does it mean binding and what is a binding tool?
3. What does it mean parsing and what is a parsing tool?
4. How is JAX-B related to mapping,binding and parsing?

I am seeking for a good answer built by you, not just a copy paste from google(Ive already been online a few hours and only got confused).
