The simple configuration of Tomcat and the application of the default Web App

Specify the Tomcat port:
Server.xml:
<connector port= "8080" protocol= "http/1.1"
connectiontimeout= "20000"
redirectport= "8443"/>
To open the Servlet debugger:
Open the following code comment for the Web. XML under Tomcat conf:
<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping>
Allows the servlet to run without modifying the Web app's Web-inf/web.xml file. You only need to copy the servlet to the Web-inf/classes directory, using the URL http://host/servlet/ServletName (the default Web app) or http://host/webAppPrefix/ Servlet/servletname (custom web App) you can use it
Test whether Tomcat and JDK are well-configured:
Run tests on your computer, you can use localhost in the URL of host
Tomcat html/jsp Directory:
Install_dir/webapps/root (or Install_dir/webapps/root/somedirectory)
Write hello.html and hello.jsp into the root directory under Tomcat under WebApps, using localhost:8080/hello.html and other access
You can also place the servlet there, and if the servlet is placed under a package, the server must have a directory that matches the package name. and the access package name in the browser is used. Delimited
Http://localhost:8080/servlet/HelloServlet
Http://localhost:8080/servlet/com.zhen.test.o1.HelloServlet2

When you use TOMCAT6 to open the Servlet debugger, Tomcat initiates an error:
Servlet of Class Org.apache.catalina.servlets.InvokerServlet is privileged and cannot are loaded by this Web application
You need to add two attributes to the Tomcat/context.xml:
Reloadable= "true" privileged= "true"

Simplify the way you deploy Tomcat:
1. How to copy shortcut paste
Source code files are not expected to appear on the real deployment server
2. javac-d parameter can specify the compilation location of Javac
Javac helloworld.java-d D:
3. Use IDE to complete deployment
4. Using Ant or similar tools

Default Web App Deployment:
Tomcat:
HTML and JSP pages:
Main position:
Install_dir/webapps/root
The corresponding URL:
Http://host/SomeFile.html
Single servlet and utility class files
Main position:
Install_dir/webapps/root/web-inf/classes
The corresponding URL (servlet):
Http://host/servlet/ServletName
More specific locations (classes in the package):
Install_dir/webapps/root/web-inf/classes/packagename
The corresponding URL (the servlet in the package)
Http://host/servlet/packageName.ServletName
Servlet and Utility class files bundled in the jar file
Position:
Install_dir/webapps/root/web-inf/lib
The corresponding URL (servlet):
Http://host/servlet/ServletName
Http://host/servlet/packageName.ServletName
