1, Apache Http server is, Tomcat is a web server, JBoss application server.
2, Apache parse static html files; Tomcat jsp dynamic pages can be resolved, but also act as a servlet container.
JBoss also has the following six advantages:
1, JBoss is free, open-source implementation of J2EE, it is distributed under the LGPL license.
2, JBoss required memory and hard disk space is relatively small.
3, installation is very simple. JBoss unpacks the packed files and then configure some environment variables on it.
4, JBoss able to "hot deploy" deployment BEAN BEAN simply copy the JAR files into the deployment path on it. If there is no load on the load it; if you have loaded on to uninstall, and then the new LOAD.
5, JBoss and Web server running in the same Java virtual machine, Servlet calling EJB does not pass through the network, thus greatly improving operational efficiency and improve safety performance.
6, the user can directly implement J2EE-EAR, instead of separate embodiments EJB-JAR and Web-WAR before, very convenient.
JBoss installation and configuration can be copied directly used, but to change% JBoss-HOME% binrun.bat JAVA-HOME in the setting change native JDK directory. JBoss run.bat to start running
close JBoss: JBoss close the DOS window, or press "CTRL + C".
