The server is the core of a Java application. It provides the backend services that are required to run the application, including persistence and security.
The server can be an application server, or it can be a servlet container or web server.
A Java EE application server is an application server that complies with one of the Java EE specifications. It will include a number of APIs and services that are required to run Enterprise JavaBeans (EJB), JavaServer Faces (JSF) and other enterprise software applications.
A servlet container or web server is a software program that provides HTTP request/response processing for web resources on the Internet or local intranets. The servlet container receives incoming requests from clients and forwards them to handlers (also known as Servlets) in order to fulfill those requests.
Server For Java Application
A Java server is a piece of software that runs in the background and provides services to users. Typically, Java servers are used to run web applications. They are also used to process business logic and perform other tasks.
Application Server Software
An application server is software that allows multiple users to access applications at the same time over a network connection using protocols such as HTTP or HTTPS (Hypertext Transfer Protocol Secure). It provides security features such as user authentication
Java Application Server is a software product that you can use to run your Java-based applications on a server computer. There are many different types of Java application servers with varying capabilities and features.
Java Application Server Software
A Java application server is different from a web server. A web server is used to host websites, while a Java application server is used to host business logic-based applications. An application can be thought of as a collection of objects that work together to perform some function or set of functions.
A Java EE application server provides support for developing, deploying, managing and running enterprise applications based on the Java platform.
The Java EE specification defines the following:
J2EE API – This API defines interfaces for each component in an application, including user interface components (windowing toolkits), presentation services (bean containers), business logic components (container controllers), persistence services (entity bean managers), transaction management services (transaction monitors), security services (identity stores) and other miscellaneous services such as configuration management services or messaging support.
JDBC API – This API provides access to relational databases from within applications developed using the J2EE specification by defining methods for connecting to databases and executing SQL statements against them.
Java servers are server applications that run on the Java platform. They are typically used to run web servers and enterprise application servers, but can also be used for other purposes.
Java EE applications (Enterprise JavaBeans) are deployed to a JEE server. Web applications are deployed to a servlet container or JEE server. The most common Java EE application servers are Oracle WebLogic Server, IBM WebSphere Application Server and Red Hat JBoss Enterprise Application Platform (JBoss EAP).
The following Java EE application servers are also available:
Apache Tomcat is an open source implementation of the Java Servlet, Spring MVC and Struts 2 frameworks. It is very popular inside large companies as it’s easy to install and maintain, doesn’t require much administration and has good performance. However, it does not have many of the features needed by large enterprises such as scalability or high availability features that come with commercial products like Oracle WebLogic Server or IBM WebSphere Application Server.
Java Server
The Java Development Kit (JDK) is a toolset for developing and running Java programs. It includes the javac compiler, the Java runtime environment (JRE), development tools such as the debugger and class libraries.
The JDK is available for Windows, Linux, Mac OS X and Solaris operating systems.
Java Web Server
A java web server is a software application that provides a web server functionality to host web applications or websites written in java programming language. It is also known as servlet engine or servlet container.
Java servers are software that host Java applications. They can be used to run a single application, or many applications.
There are many different types of Java servers and they have their own strengths and weaknesses. Some are built for high performance, others for scalability, some for security, etc..
If you want to learn more about Java servers I suggest you read my article “Java Web Server Tutorial”.
In this article I’ll introduce some of the most popular Java servers: Tomcat, Jetty, Glassfish and JBoss.
The most common uses of a server are:
Web Server,
Application Server and
Database Server.
A web server can be described as any computer system that is used to provide services to users over the web. It is also referred to as a HTTP server or simply a web server. This software allows you to share documents and data over the internet using hypertext transfer protocol (HTTP) which is the same protocol that you use when you browse the internet.
The application server software is used for running Java EE applications on an enterprise network. Application servers support EJB and CORBA/IIOP protocols in order to communicate with other components in the system. Some of the popular application server software packages are BEA Weblogic Server, IBM WebSphere Application Server, Oracle WebLogic Server, JBoss Application Server etc.,
The database server software is used for storing and managing large amounts of data such as customer records, product information etc., The databases can be either relational or non-relational depending upon their functionalities. Some of the popular database servers include MySQL, Oracle Database and Microsoft SQL Server etc.,
Java Web Server
A web server is a computer that provides access to resources on the World Wide Web. The term was coined by Tim Berners-Lee, who built the original web server software to serve the needs of the World Wide Web project.

Java EE (Enterprise Edition) and J2EE (Java 2 Platform, Enterprise Edition) are application server specifications for developing and deploying enterprise-scale applications on a Java platform. They provide standardized mechanisms for managing different components of an application as well as for distributed communication between components.

In Java EE, the application server is responsible for providing the runtime environment for applications. The application server can be either a Java SE or Java EE component.
The following example uses Tomcat, which is a Java SE application server. This example does not use any features from the JPA specification, so it only needs to run on a Java SE environment.
Java is a programming language developed by Sun Microsystems in 1991. The language has been quite popular and even used in many web-based applications.
Java is a platform used for building applications and applets.
The Java platform consists of the following:
The Java Runtime Environment (JRE) is an implementation of the Java virtual machine (JVM) and the Java Development Kit (JDK).
The JRE is a software component that provides an execution environment for Java code on computers where an operating system cannot be changed or replaced. For example, it runs on Microsoft Windows, Unix and Linux systems. The JDK includes the JRE, together with tools needed for developing and running programs written in the Java programming language as well as writing applets to run within web pages.
Java is a programming language used to develop software applications and applets. It is a general-purpose, concurrent, class-based, object-oriented language that is also considered as a platform because of its rich set of APIs.
The Java EE platform is an application server that runs on a Java Virtual Machine (JVM) and provides services to the applications. The Java EE platform supports both enterprise and web applications.
Java Enterprise Edition (Java EE) is a group of specifications that define how Java can be used in enterprise computing environments. These specifications were developed under the Java Community Process.
Java EE Application Server
The Java Platform, Enterprise Edition (Java EE) is a platform for building and running Java applications in the enterprise. The Java EE platform contains a set of APIs for developing web and enterprise applications, including servlets, EJB, JMS, JPA, JTA and more. The Java EE platform also includes a set of specifications that define a standard way to deploy enterprise applications on multiple platforms. For example, an enterprise application can be packaged as an EAR file (Enterprise Archive) containing all its classes along with resources like configuration files and scripts, which then can be deployed on any supported server platform. This makes it easier to deploy your application on different servers without having to rewrite any code or make any changes in configuration files or scripts.
