i want to implement GWT RPC and simultaneously want to access database at server side(registerServiceImpl.java) using hibernate.. i think now a make clear almost of my project.. if somebody could help me the i will be thankful to him..
No there is only single exception that a written previously...
i have used try catch on the code written above session etc..
i think it is due to because server does not find hibernate library at its end
Hello Everybody,
i am making a web application which is based on GWT instantiation.. at server end i want to use hibernate for accessing database but when i run it on eclipse 3.2 having GWT instantiation plug in(after writing all the code of client side and server side including use of hibernate)it is giving this error

Error is org.hibernate.HibernateException: Could not parse configuration: /hibernate.cfg.xml

which comes for these lines in the server side code


SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
Session session =sessionFactory.openSession();
Manager manager = new Manager(session);
user=manager.searchUser(username);

where user is object of database entity and manager is the class which access the database ...

my hibernate.cfg.xml is as following

///////////////////////////////

<?xml version='1.0' encoding='utf-8'?>
