I started the standalone.jar on port 8081 with the following and now
I am trying to access it from a servlet. Yet, I get an Exception
where it can't `getSession` in my SessionFactory class. I am not sure
what is going on. The one thing I checked is the looked so that it is
"jcr/repository". I also checked that the ClientRepositoryFactory class
is in my dependencies. Could it be the way I am creating the context.xml?
See below for details.
Thanks,
Brian
The following is the exception shown on the jsp page.
