You can use the local service to test how TOMCAT configures domain names.

Use your own machine as the server configuration result. The test is successful.
The configuration is as follows:
Modify the file server. xml under \ Tomcat-7.0.29 \ conf in your tomcat installation directory,
Open it in notepad and find:
<Connector
Port = "8080"
To:
<Connector
Port = "80"

Find again:
<Engine
DefaultHost = "localhost"
Name = "Catalina">
<Realm className = "org. apache. catalina. realm. UserDatabaseRealm"/>
<Host
AppBase = "webapps"
Name = "localhost">
To:
<Engine
DefaultHost = ""
Name = "Catalina">
<Realm className = "org. apache. catalina. realm. UserDatabaseRealm"/>
<Host
AppBase = "webapps"
Name = "">
Change the port to 80, and set defaultHost and name to the domain name you applied.
Now, let your friends on the Internet access the JSP server built on your own machine! I have learned many details,
Writing them one by one is too cumbersome!

The IP address is used for LAN access because there is no domain name resolution system or software like oray.
Make a Domain Name Server by yourself!
Of course, the local localhost can be accessed with a domain name. Modify C: \ WINDOWS \ system32 \ drivers \ etc \ hosts

File,
Open him in notepad

To:
Wyptest.com. Remove the comment.

Create a folder corresponding to your domain name under the \ conf \ Catalina directory, for example, ww.wyptest.com. Create a ROOT. xml file under the folder.
Content:
<? Xml version = '1. 0' encoding = 'utf-8'?>
<Context displayName = "Welcome" docBase = "" E:/tomcat-7.0.29/webapps/flexpaper-demo/"path =" ">
</Context>

Access address: http://www.wyptest.com/flexpaper-demo/documentUpload.jsp results run successfully, please note that the domain name has changed.
