How to access the Tomcat publishing Web feature that comes with MyEclipse

Typically, a Web project is published under Tomcat under the WebApps file directory.
When visiting:
For example: The Web App project name is: Webmanager, after deployment to Tomcat, is deployed in the HTTP protocol header/tomcat/webapps/webmanager, the URL is: HTTP protocol header//localhost:8080/ Webmanager.
Whenever you visit a site page, the Address bar is: HTTP protocol header//www.1234.com/login.html. So the general practical use is not with Webmanager (so-called Project name).

Here's how:
1. Select the Web project that we want to manipulate, right-click, select Properties, it will appear
2. You need to change the value of the Web Context-root to "/". Remove the Webmanger to get rid of it.
3. Deploy the project Webmanger to the root folder under the Tomcat root directory.
4, in the visit, there is no need to put the name of the project.
