JavaBeans: JavaBeans are recyclable software components for Java which by using a builder tool can be manipulated visually in line to a specific convention. JavaBeans create Java Components that can be composed together into applets and applications.For passing as a single bean object instead of as multiple respective objects, they are used to encapsulate many objects into a single object(the bean).
Enterprise JavaBeans(EJBs): EJBS are server-side programs which generally implement middle layer business performance. Enterprise JavaBeans are intended to handle such frequent concerns as perseverance, transactional integrity and security in a 3-way model, which gives programmer freedom to focus on the specific problem in hand. It tightly couples with COBRA, COBRA-HOP compatibility by the EJB-to-COBRA mapping.
The difference between JavaBeans and Enterprise JavaBeans(EJBs) are as following:
|1.||Javabeans is a component technology to create universal Java components.||Even though EJB is a component technology, it neither reconstructs nor enhances the original JavaBean specification.|
|2.||Beaninfo classes, property editors or customizers can be present in Javabeans.||No perception of Beaninfo classes, property editors or customizers is in Enterprise JavaBeans and no additional information is provided except that described in the deployment descriptor.|
|3.||An external interface called a properties interface is given in JavaBeans, that allows a builder tool to describes the functionality of a bean.||A deployment descriptor is given in Enterprise JavaBeans to interpret the functionality to an external builder tool or IDE.|
|4.||There is no further category of Java Beans.||Enterprise JavaBeans are categorized into two types – session beans and entity beans.|
|5.||JavaBeans have not any definite support exists for transactions.||EJBs may be transactional and transactional support is provided by the EJB servers.|
|6.||JavaBeans are designed for a single process and are localized||EJBs are remotely executable components or business objects.|
|7.||JavaBeans may be visible or non-visible components.Visual GUI component (Button, listbox, graphics) are examples of JavaBeans.||An EJB is a non-visual isolated object.|
|8.||JavaBeans has components bridges.A JavaBeans can also be arranged as an ActiveX control.||ActiveX controls are designed for the desktop so EJB cannot be deployed as an ActiveX control.|
|9.||JavaBeans are mainly designed to run on the client side whereas one can develop server side JavaBeans.||EJBs are deployed on the server-side only.|
