| <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</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 specification go to the following Web |
