Help with importing, updating and erasing content.

[hsp <pi...@ibest.com.br>]

Hi;

Could you help me with this doubt...
I need some example, or where I can find it, on how to put some content in somewhere in a repository (informing all the properties it has).
Also I want to know how I can Know what are the properties the node must have by default? And how can I update these properties?
In the case of erase the content, how could it be?
Another doubt, what is the better way to instanciate a repository to work in it? I saw some ways to do it.
Please, I'll be very glad with these helps. I am new in jackrabbit and jsr170, any help would be very appreciate. I want to build an facade to call the basics functions of jackrabbit, to use it in a webapp.
I am sorry if these kind of questions could not been posted here.

Thanks
Helio
