Answer 1

You can definitely use Annotations to map Objects to Tables. Essentially you need to use JPA (Java Persistence Annotation), there are also some Hibernate specific annotations that you could use.

In short, an Object representing a Table should be marked with @Entity annotation. There are bunch of other annotations / attributes that you need to know to make things work

Answer 2

I think you might want to use Mapping secondary tables from the hibernate documentation.
It appears that you can join data from multiple tables into a single shared entity bean,

It seems that you cannot use annotation for that so far. Auxiliary database objects are not covered by annotations (in Hibernate 3.6): Hibernate 3.6 Docs
