on the following link is an example
very good but with ejb

but I'm going to do without an ejb

1: In our project web

2:
3:
then next, next

4: In our new servlet

Now we have this core code

in this code we enter data into our database

-> into your servlet enter the following code

e = new Company Company ();

e.setNombre ("best");
e.setDireccion ("Santiago");
e.setRut ("1111");
persist (e) / / call our code above

remember that entities are representations of type beans
our tables in our data base

and finally to retrieve information we must take in order
Query q = em.createNativeQuery ....
this whole process is very similar to code shown in the photo
and to traverse the collection deal
