EJB 3RD EDITION -Richard Monson-Haefel Authors?Note In the winter of 1997 I was working on a distributed object project using Java RMI. Not ingly, the project failed miserably because Java RMI didnt address performance, scalability, fail-over, security, and transactions; qualities of service that are so vital in a production environment. Although that lesson was not new for me-I had seen the same thing happen with CORBA-the timing of the project was especially interesting. It was at that same time Enterprise Javabeans first introduced by Sun Microsystems had Enterprise available earlier, that same project probably would have At the time I was working on that ill-fated Java RMI project, I was also writing a column for JavaReport Online called the"The Cutting Edge.
