Can JSP and Servlets do everything doing by EJB

Hi,

Please let me know whether we can use JSP and Servlets to do everything we have done using EJB?

Yes, you could implement all the services provided by EJB3 yourself with servlet+jsp and POJOS, but depending on which features you need, this could mean a lot of additional work...

Thank you very much...

If it's just the EJB API you wish to avoid, then there are alternatives like Hibernate (which has its own API).

Did you mean JPA?

No, I meant Hibernate's own API.

As a replacement for EJB or JPA..?

Neither. Hibernate is a JPA implementation, and has its own non-standard ORM API. As far as an EJB replacement goes, it could be used to replace Entity beans only.

Hibernate is just an ORM framework and a reference implementation of the JPA standard. I can imagine Spring + Hibernate as a replacement for EJB and not just Hibernate.

yes, Spring offers the "lighter" of EJB version..
Spring also provides API to wraps up Hibernate through HibernateTemplate..
it could ran in Tomcat Servlet container..
but, i think EJB3.1 is good news also for EJB developer..

it could ran in lighter EJB Container, such as Glassfish V3..
