如何通过 javac 编译一个 java web 应用程序？

Question

I have a traditional Java web project, it's structure displayed as below

|-lib
|-src
   |-main
      |-java
      |-resources
|-wbeapps
   |-WEB-INF
      |-web.xml

I compile and run this application by IDEA's tomcat configuration before, all the issues about compile, run and deploy is done by IDEA.

Now, I must modify a java file of src\\main\\java\\xxx , and this modification is absolutely correct, then not using IDEA or Eclipse to achieve the compilation and deploy to Tomcat.

How can I do that without IDEA or Eclipse, just use javac or other tools? Please give me some advices, thanks.

Answer 1

You're going to need to have a war (web application archive) file if you want to deploy to Tomcat. To generate a war file, first, compile all of your files using javac, and then run the jar command:

jar -cvf project.war * 

This command should be run from the root project directory (not inside WEB-INF or any other folders).

The -c option specifies that you want to create a file, the -v option will generate verbose output, and the -f option allows you to specify the archive name.
