Using ant to compile and publish projects

This article uses an example to explain how to compile and publish projects through Ant.
This example organizes the project according to the following directory structure.

D:/web/antsample Project root directory d:/web/antsample/src source code directory D:/web/antsample/src/sample/helloworld.java sample HelloWorld code file d:/ Web/antsample/app application directory d:/web/antsample/app/index.jsp default home file d:/web/antsample/app/web-infd:/web/antsample/app/ Web-inf/web.xml Application description file d:/web/antsample/app/web-inf/lib Application Library Directory d:/web/antsample/context.xml application Environment profile, data source, Information such as application path (path), document Path (DocBase) is configured here. D:/web/antsample/build.xml

To run this example, you must modify the full path of the Tomcat directory in Build.xml and the corresponding information in Context.xml.
Go to D:/web/antsample, enter the ant command, compile the program, and package the generated class file into a jar and decorate it to app/web-inf/lib.
Run ant deploy to copy Context.xml to Tomcat/conf/catalina/localhost/antsample.xml and complete the program layout.
Run ant undeploy to remove the Tomcat/conf/catalina/localhost/antsample.xml file to complete the uninstallation of the program.

Now you can enter Http://localhost:8080/antsample to access the example program.
