softeng17b's Introduction

Example web app

An example of a gradle-based Java web app.

The example demonstrates the use of gradle for developing a Java web application that can be deployed to Servlet containers such as Tomcat, Jetty, etc.

Google Maps API Key

You need to get an API Key for the Google Maps examples to function properly.

The API key should be placed into the src/main/webapp/conf/app.properties file.

Gradle tasks

Invoke gradle using the following command:

> ./gradlew taskA [taskB]

Some useful tasks include:

classes: compile all sources.
war : generate war file (to be deployed to a container like tomcat).
appRun : compile and deploy everything into an embedded jetty container, automatically re-deploying the files you change during its execution.
