Greetings!

I am having some problem in inserting some records in MySQL 5 database using EJB 3 Stateless SessionBean with the EntityManager injected in it.

persistence.xml


EmployeeBeanImpl.java


Test1.java


When I’d ran the Test1.java it returns the following error below:

My suspected problem were on the EntityManager, but not perfectly sure about that, and how to persist an entity in a session beans.

Hoping for your help with regards to the stated problems.

Thanks very much. I really appreciated your time.

Cheers!

em.getTransaction().commit();

Try removing this line. I feel it should not be there n may be it is creating the problem.

hi guyz,

got it solved.

i am using glassfish, what i did was changed the set-up configuration in Resources> JDBC> JDBC Resources JNDI Name: jdbc/__default to the database schema defined in my pointing persistence.xml file.

thou, i am not sure 'yet in the case if my application would like to access multiple database schemas at the same time.

thanks very much!

cheers!
