For the csdn blog of Sunday follow_24, click: 82220081 Like tomcat, JBoss is a javaweb application server or javaweb container. Of course, the two are also different: TomcatIs a JSP/servlet containerJBossIs the Jee container, jee includes JSP/servlet, JMS, EJB, JAX-WS, JAX-RS, CDI and so on. Tomcat is fully open-source, and the open-source community maintains product updates.JBoss has two versions: open-source and enterprise-oriented, which are s

I. JDK Installation
First install JDK and configure the environment variable (PATH, CLASSPATH, JAVA_HOME ).
For details, refer to JDK installation and environment variable configuration in Windows.
II. Introduction to Jboss
Configure the JBoss data source, why configure the data source in JBoss? This is actually a manifestation of object-oriented thinking: managing access to a database through a container. At first we accessed the database through JDBC, and what connection and command were created by ourselves. But every time you open the database is consumed resources, so there is a database connection pool, in advance to est

You can download the tomcateclipse plug-in to easily debug applications in IDE (seeCom. sysdeo. Eclipse. Tomcat ).
However, if the application is enterprise-level and requires EJB container deployment, Tomcat will be powerless. At this time, we can select JBoss as

Recently prepared to study the seam framework, focusing on the content of the JBPM Integration section. Because seam is an jboss product, it is officially recommended that the JBoss application server be used. Personally think that thing too much more than 100 MB, lazy download! Looked at the next seam document, which said that you can use tomcat+ embedded JBoss,

usually we do the system commonly used Tomcat server, so also more familiar. For systems that need to use distributed technologies such as EJBS, often using WebLogic servers and JBoss servers, what is the difference between these servers and what servers should our systems best deploy? Let's examine it in detail below. Tomcat Server: the Tomcat server consumes less resources, is stable, and is free. is a lightweight server, mainly for small and mediu
applications with high hardware requirements. It is not recommended for the current situation where small and medium applications are mainly used in China.
Although domestic developers have long been used to the dashboard, I think it is better to prevent them from getting started. We should join the OpenSource ranks as early as possible to promote the development of the domestic software industry.
Eclipse, JBoss, and MySQL recommended in this article
J2EE is good. As a development environment, if you use the classic configuration: JBuilder + Weblogic + Oracle, you are comfortable, but the price is amazing. This configuration is mainly for large-scale or super-large applications with high hardware requirements. It is not recommended for the current situation where small and medium applications are mainly used in China. Eclipse, JBoss, and MySQL recommended in this article are well-known open-source
