Alex,
You should be fine as long as you've only got a single web.xml per
webapp. :) It is thread safe.
I'm on the stripes IRC channel most of the time if you'd like to have a
more interactive discussion.

I just discovered that you write stipernate, which I switched to to
try and get something working, which I did, but I'm a bit concerned
that by using a singleton to return a session, it's not thread safe.
Should I be worried?

Hi Alex,
There is only one thing in web.xml that you need to set inside of
your Stripes <filter>. You need to tell Stripes to load
Stripersist as an extension with the following lines:
<init-param>
<param-name>Extension.Packages</param-name>
<param-value>
org.stripesstuff.stripersist
</param-value>
</init-param>
You may have other extensions too in which case you can separate
the values with whitespace and/or commas.

I'm basing my code on the code from the new stripes book, and
Stripersist.getEntityManager() is returning null. I get the
following two lines in my log:
1 [main] INFO org.hibernate.annotations.common.Version -
Hibernate Commons Annotations 3.1.0.GA <http://3.1.0.GA>
5 [main] INFO org.hibernate.ejb.Version - Hibernate EntityManager
3.4.0.CR1
Which gives me the impression that Hibernate Entity Manager is up
and running, though I might be wrong. I didn't see that it told
me I had to add anything to my web.xml to make it work, though I
was skimming pretty fast tonight, so I might have missed it.
Thanks,
Alex
