Connect remotely located Java applications and database

The Java application which serves as client-side software should be implemented as form of JavaBeans which are serializable.  Server-side software should be adopted to EJB(Enterprise Java Bean) which uses JBoss application server to communicate with database and client-side software components.What is serialization:In computer science, in the context of data storage and transmission, serialization is the process of converting an object into a sequence of bits so that it can be persisted on a storage medium (such as a file, or a memory buffer) or transmitted across a network connection link to be "resurrected" later in the same or another computer environment.[1] When the resulting series of bits is reread according to the serialization format, it can be used to create a semantically identical clone of the original object. For many complex objects, such as those that make extensive use of references, this process is not straightforward.What is JBoss:JBoss Application Server (or JBoss AS) is a free software/open-source Java EE-based application server. Because it is Java-based, the JBoss application server operates cross-platform: usable on any operating system that Java supports. JBoss AS was developed by JBoss, now a division of Red Hat.
