Stupidly Simple WAR files

Overview

WAR files are ways to deploy a project onto a Tomcat server. They contain all necessary JSP pages, java classes, jar files, etc. to run a service. I always have an issue with creating them since it can be confusing setting up the proper directory structure, making sure everything is in place, etc. This is the quickest way I know to create WARs without needing an IDE.

Process

1. Create a new directory (Referred to as foo from now on) and copy all your JSP files there.
2. In foo, create a directory WEB-INF/lib
3. Copy all jar files you are dependent on into WEB-INF/lib/
4. Create a jar of your source. For example if your project's compiled class files are in a directory called bar you would run: jar -cvf bar.jar bar/
5. Copy bar.jar to WEB-INF/lib/
6. In the bar directory run the following command jar -cvf projectName.war .
7. Drop projectName.war into webapps in Tomcat and restart Tomcat, and you should be set.

Conclusion

As trivial as this seems I couldn't really find an easy breakdown online. Some purists may not like that the directory structure isn't full (No meta-inf, web.xml, etc.) and that I used a jar instead of classes.
