Servlet|xml Tomcat's startup files are configured on a component basis:
<server>----Root Components
Includes properties: port= "8005" shutdown= "shutdown" debug= "0"
The following include other components:
1, <listener > components
Used to monitor some server events
<listener classname= "Org.apache.catalina.mbeans.ServerLifecycleListener"
debug= "0"/> is the container life cycle listener
<listener classname= "Org.apache.catalina.mbeans.GlobalResourcesLifecycleListener"
debug= "0"/> Resource Lifecycle Listener
2, <GlobalNamingResources> components
You can set up a number of global resources that are based on Jndi:
<GlobalNamingResources>
<!--Test entry for demonstration purposes-->
<environment name= "Simplevalue" type= "Java.lang.Integer" value= "/>"
<!--Editable User database that can also is used by
Userdatabaserealm to authenticate users-->
<resource name= "Userdatabase" auth= "Container"
Type= "Org.apache.catalina.UserDatabase"
description= "User database" can be updated and saved ">
</Resource>
<resourceparams name= "Userdatabase" >
<parameter>
<name>factory</name>
<value>org.apache.catalina.users.MemoryUserDatabaseFactory</value>
</parameter>
<parameter>
<name>pathname</name>
<value>conf/tomcat-users.xml</value>
</parameter>
</ResourceParams>
</GlobalNamingResources>
3, <service name= "Catalina" > Components
Only one <engine > component and multiple <connector > components can be set below
4, <engine > Components to set up a number of <context> components (this is our most important component)
The basic configuration is: <context path= "/app" reloadable= "true" docbase= "D:\eclipse\workspace\webstudy"/> He set up a context:http:// Localhost:8080/app
