Note java.beans: This package has been deprecated in Java 9 and later versions, in favor of using annotations and other modern ways of creating beans. Using it in production code is not recomended.
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:
S.No. | JavaBeans | Enterprise JavaBeans |
---|---|---|
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. |
