| <p><b>Enterprise <tm tmclass="special" tmowner="Sun Microsystems, Inc." |
| tmtype="tm" trademark="JavaBeans">JavaBeans</tm></b> is a standard |
| server-side component model for distributed business applications. |
| The EJB specification is part of the <b><tm tmclass="special" |
| tmowner="Sun Microsystems, Inc." tmtype="tm" trademark="Java">Java</tm> Platform |
| Enterprise Edition</b>.</p> |
| <p><b>EJB 3.0 and EJB 3.1</b> makes it much easier to develop EJBs, |
| using annotations rather than the complex deployment descriptors used |
| in version 2.x. The use of home and remote interfaces and the <i>ejb-jar.xml</i> file |
| are also no longer required in this release. They are replaced with |
| a business interface and a bean class that implements the interface.</p> |
| <p>For more information about EJB 3.0 and EJB 3.1 specification go |
