Java Enterprise and Web Technologies

Java struts saves your time by allowing you to view complex applications as a series of basic components such as views, action classes and model components.

It is responsible for the java classes that implement the enterprise bean's business methods and the definition of the bean's remote and home interfaces.

It can combine enterprise beans with other type of application components when composing an application.

Session beans will disappear if the server crashes and is restarted.

With Ajax, when the user clicks edit, you can redraw the static table into a table with editable contents.

EJB container provider provides support for versioning the installed enterprise bean components.

This file format is the contract between the bean provider and application assembler, and between the application assembler and the deployer.

Entity beans represent a business object in a persistent storage mechanism such as a database.

It uses runtime monitoring and management tools provided by the EJB server and container providers to accomplish the configuration and administration of the enterprise's computing and networking infrastructure.

This file is specified in the deployment descriptor of the ejb-jar file using the optional ejb-client-jar element.

Enterprise java beans architecture will provide interoperability between enterprise beans and non java programming language applications.

In entity bean's deployment descriptor, the fields that the container should managed must be specified.

It generates the additional classes and interfaces that enable the container to manage the enterprise beans at runtime.

It is a web server.

SOAP's key advantages are platform and language independence, plus its ability to traverse firewalls by using HTTP as its transport protocol. This makes it ideal for heterogeneous environments. SOAP is XML-based, not HTML-based, and is designed for WAN/internet communication, not just LAN.
