How to change the log4j level

Change DEBUG to INFO or vice versa in src/main/resources/log4j.properties first line.

This change requires building a new WAR file

How to build the WAR file

In the project root directory, run: gradlew war

This will generate NumSum-1.0-SNAPSHOT.war into the build/libs directory

How to deploy the WAR file to Apache Tomcat

0. Install Tomcat (this was tested on Tomcat 9.0.64, since Tomcat 10 does not seem to work for whatever reason)
1. To deploy the application at the root (http://localhost:8080/), rename the generated WAR to ROOT.war.
   • To deploy it at something else, rename the WAR file to something else, e.g. sum-app.war. This will make the application available at http://localhost:8080/sum-app/
2. To change the port from 8080 to 1337, edit conf/server.xml and change the Connector port from 8080 to 1337.
3. Copy the WAR to your Tomcat webapps directory, make sure there are no other webapps present starting with 'ROOT'.
4. Start Tomcat by running startup.sh (or startup.bat if you are on Windows) located in the bin directory.
5. The application should be now running and be ready for use.
6. To shut down Tomcat, run shutdown.sh (or .bat) located in the bin directory.

How to run the application locally

Since this project uses the Gradle WAR plugin, it is not necessary to use an external Tomcat to run it.

1. Run gradlew tomcatRunWar in the project root.
2. The application should now be running at http://localhost:1337

Other info

• Tests can be executed by running gradlew test in the project root
• NB! Sometimes when running the application locally and shutting it down, it is possible that the process stays alive and on the next startup will give an error about the port being in use. If that is the case, manually kill the process in Windows task manager/Linux alternative.
