Java application server article and products

Java application servers are component-based software that resides in the middle-tier of a server centric architecture. They provide middleware services for security, state maintenance, along with data access and persistence. A Java application server sits below a Web server.

A Java application server creates an infrastructure for deploying applications that are usually called components. The components are written in object programming languages such as Java, C#, C++, and others. Components used in the middle tier are a common way to realize the high-level abstractions of business processes and workflow.

A Java application server can have:

	Access to external Web Services. This could be virtually anything.
	Access to other Internet resources. This also could be most anything: weather reports, currency converters, news feeds, and so on.
	Access to internal Web Services. An example of an internal Web Service might be the validation of an account based on data input over the Internet/Intranet and data stored in an existing database.
	Access directly to internal system directly, bypassing Web Services. Direct access to an existing database might be an example of this access.
