Hi everyone,
It´s my first post to the list so I'm sorry if I'm broking any rules or
writing in a wrong text format.
I'm here to learn and I hope I'll with you guys.
Firstly, I should explain my huge(or not?) problem.
Since 2 days ago, I'm having this persistence error in my project.
I mean, when I get my program running, I have this follow message:
javax.persistence.PersistenceException: No Persistence provider for
EntityManager named classePer

I have no idea why I'm having this. Then, I have thought that is a
wicket problem because when I use the same codes in a Desktop
application I can run that very normal.
I've tried to put the persistence.xml in several places, but I didn't
have any sucess so far.
I've also tried to add (even manually), all the .jars related to the
hibernate lib. However, I still continued with the same problem.
I kinda lost myself and I do not know how to fix my code or even how to
do any modification to get my web application running as normal as my
desktop application.
Thank you guys,
