You could find this imformation on an "Expert One-on-One J2EE Development without EJB" book. There is two excerpts from this book that benefits to you.

lately EJB is not the only approach people are taking in the finance & banking sectors.

People started using Webservices in a full scale. That includes the service hosted on a J2EE container and accessed from a .net client(which can be developed much faster compared to a JSP/Servlet centric development of a client)

EJB seems to be one of many approaches you can take. Options to take are JDBC and Data Access Objects, JDO (Java Data Objects), object-relation mapping tools like Hibernate and Toplink. There are arguments for and against all of these, and it would probably depend on the project using them. Lately EJB have been getting some bad press due to project which have used EJB and made mistakes with them, not understanding their limitations. One aspect that can cause problems is the use of EJB QL and container manager relationships. EJB QL is still very limited compared to SQL, and bulk operations are probably best done using SQL.

you can use EJB component but you must understand in detail/information/limitation/problem of EJB component.

And have another solution to solve this task such OR-mapping (Hibernate, TopLink).

Jasmine,
Ofcourse not, EJB is just a part of this big cloud of tecnology. Its in news because of its usability and performance. Sun has successfully created a platform to merge good thoughts easily. This helps businesses find find quick and reliable solutions. If one desires to implement ideas as substitution it is advisable to have constant consultation with forums created.
