This article mainly introduces the relevant knowledge of linux middleware, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value. I believe you will gain something after reading this linux middleware article. Let's take a look at it.

Linux middleware are: 1, tomcat, a server software of servlet specification; 2, weblogic, a middleware based on j2ee architecture, which simplifies the development of portable and extensible application systems; 3, jetty, written in Java language, can realize automatic testing; 4, JBoss, and so on.

The operating environment of this tutorial: linux5.9.8 system, Dell G3 computer.

What is middleware?

Middleware is a kind of independent system software or service program, which is used by distributed application software to share resources among different technologies. Middleware is located on top of the client / server operating system and manages computer resources and network communications. Is software that connects two independent applications or independent systems. Even though they have different interfaces, connected systems can still exchange information with each other through middleware.

One of the key ways to implement middleware is information transmission. Through middleware, applications can work in multi-platform or OS environments.

Middleware is between the operating system and the application software, which provides service functions for the application software, such as message middleware, transaction middleware, application server and so on. Because it is between two kinds of software, it is called middleware.

Common Middleware of linux

1 、 tomcat

It is a server software of java language servlet specification.

Suitable for local development, small projects, or personal development (free open source Web application server), Apache serves HTML pages, while Tomcat actually runs JSP pages and Servlet, but Tomcat is not as capable of handling static [HTML] as Apache servers

Features:

Support for the latest standards (SUN experts often hang out with TOMCAT developers)

Update quickly

Cross platform

Small size, easy to install and deploy

2 、 weblogic

Large projects or commercial projects, the dynamic functions of Java and the security of Java Enterprise standards are introduced into the development, integration, deployment and management of large-scale network applications. It is a middleware based on j2ee architecture produced by bea Company in the United States.

Features:

It simplifies the development of portable and extensible application systems, and provides rich interoperability for other applications and systems.

Commercial software, with complete and powerful functions, is mainly used in large projects of large enterprises.

Is a highly scalable architecture

3 、 jetty

Some sample projects or small projects often (open source servlet container) are written in the Java language. Jetty runs fast and lightweight, and can be controlled from test case in Java. As a result, automated testing can no longer rely on the external environment, and automated testing can be realized smoothly.

Features:

It is easy to use, extensible and easy to embed.

Fast and efficient

4 、 JBoss

Manage EJB containers and servers (open source projects), JBoss is distributed under a business-friendly LGPL license, and is developed by the open source community

Features:

The application server also has many excellent characteristics.

The memory and hard disk space required is relatively small.

Easy to install: after decompression, you only need to configure some environment variables.

"Hot deployment" is supported. When deploying BEAN, only copy the JAR file of BEAN to the deployment path and load it automatically; if there are any changes, it will be updated automatically.

Boss and Web server run in the same Java virtual machine, and Servlet calls EJB without going through the network, which greatly improves the running efficiency and security performance.

Users can implement J2EE-EAR directly instead of implementing EJB-JAR and Web-WAR respectively, which is very convenient.

Jboss supports [cluster]

5 、 WebSphere

IBM's software platform, which includes writing, running, and monitoring 24 / 7 industrial strength on demand Web applications and the entire middleware infrastructure, such as servers, services, and tools, required for cross-platform, cross-product solutions. WebSphere provides reliable, flexible and robust software. WebSphere is a modular platform based on open standards supported by the industry. Existing assets can be plugged into the WebSphere through trusted and persistent interfaces, and the environment can continue to be extended. WebSphere can run on many platforms, including Intel, Linux, and z/OS.

Features:

Meet the needs of a large number of applications

Runs on a variety of hardware and OS platforms

Support for distributed computing, providing transparent application or service interaction across network, hardware, and OS platforms

Protocols that support standards

Support for standard interfaces
