WebLogic Basic Concepts

      as you can tell ,TomcatIt's free and open source.WebApplication Server, it has stable performance, advanced technology and simple application, and based onTomcatof the kernelJBossin theJavathe application server domain has become the most rapidly growing application server. JBosscompared toTomcatOne of the big advantages is that not only does it provideWebContainer(servletContainer), also providesEJBcontainers that support distributed. Can sayTomcatcan do,JBosscan do almost anything.

Tomcat Is commonly used in small and medium-sized systems and is subject to both Java learners are also deeply fond of software developers. However, the simple Tomcat performance is limited, there are still many shortcomings, such as active connection support, static content, large files and HTTPS, and so on;Another big disadvantage of T omcat is that it can only run Java applications; JBoss to a great extent perfected the Tomcat the deficiencies.

Tomcat and JBoss introduced here, after all, this article is to introduce WebLogic the.

Learn to review Tomcat and JBoss, and then see weblogic It will be much simpler.

WebLogic is an Oracle - produced ApplicationServer, specifically a Java EE architecture-based middleware,W Eblogic is a Java application server for developing, integrating, deploying, and managing large-scale distributed web applications, Web applications, and database applications. Introduce the dynamic capabilities of Java and the security of javaenterprise standards into the development, integration, deployment, and management of large-scale network applications.

WebLogic Some of the great benefits:

1) Leading standards

Comprehensive support for multiple standards in the industry, including EJB,JSB,JMS,JDBC, XML and WMLmake it easier to implement Web application systems and protect investments while making it easier to develop standards-based solutions.

2) Unlimited Scalability

Beaweblogic server is known in the industry for its highly scalable architecture architecture, including client-connected sharing, resource pooling , and Dynamic Web pages and EJB component clusters .

3) Rapid development

With support for EJBS and JSPs, and the Beaweblogic Server's servlet component architecture, the market speed can be accelerated. These open standards, when combined with webgainstudio, simplify development and leverage existing skills to rapidly deploy applications.

4) More flexible deployment

BEA Weblogicserver is characterized by tight integration with leading databases, operating systems, and Web servers.

5) mission-critical reliability

Its fault tolerance, system management, and security can be verified in thousands of mission-critical environments worldwide.

6) architecture

BEA Weblogicserver is specially developed for enterprise e-business application systems. Enterprise e-commerce applications require rapid development and require server-side components to be flexible and secure, while supporting the scale, performance, and high availability required for mission-critical tasks. Beaweblogic Server simplifies the development of portable and extensible application systems and provides rich interoperability for other application systems and systems.

with its excellent clustering technology, Beaweblogic server has the highest level of scalability and availability. BEA Weblogicserver enables both Web clustering and EJB component clustering without the need for any specialized hardware or operating system support. A Web page cluster enables transparent replication, load balancing, and content tolerance, such as a web shopping cart, and component clusters that handle complex replication, load balancing, and EJB component fault tolerance, as well as recovery of State objects such as EJB entities. Whether it is a Web cluster or a component cluster, it is critical to the scalability and availability required for e-commerce solutions. Shared client/server and database connections, as well as data caching and EJBS, enhance performance. This is not available in other Web application systems.  

In addition, other Java EE application servers are: WebSphere, Sun GlassFish, resin, JBoss, domestic manufacturers are also produced by the Tongweb, Kingdee apusic application Server.
