Yes, it's closed before you have an opportunity to get a hold of it.
You could add session.close() to the end of the script.
I don't think it is a problem because after extensive testing of that script
I still only have 5 processes of postgres running.
according to the javadoc, connection.commit() releases the actual connection
to the database. The garbage collector would take care of the rest.
I just made a snippet in codeville.

Thanks, Caleb! That saved me a lot of time.
I have another question. Maybe I'm not getting the hibernate sessions
idea right, but
how can I get the current hibernate session that XWiki uses? I'm not
eager to open my own session, as
I'll have to make sure that it's closed correctly in the end.
I've tried XWikiHibernateStore.getSession() but it appears to give me
a null value.

If you don't mind declaring a dependency on
xwiki-core, you can
import org.xwiki.context.Execution
import com.xpn.xwiki.XWikiContext
import com.xpn.xwiki.XWiki
import com.xpn.xwiki.store.XWikiHibernateStore
and then use:
@Requirement
Execution ex;
XWikiHibernateStore hib =
ex.getContext().get("xwikicontext").getWiki().getHibernateStore();
and you have XWikiHibernateStore, from that you can get the SessionFactory, open a
session and do whatever.
The API:

Again I have a question. QueryManager class
allows to make queries to
the database, but, for example,
If I want to store an object in the database, I'll have to use
something similar to hibernate session's save() method.
What should I do?

Thanks, Alex! Never thought that it could be in
the "scripting"
section of docs...
