This is a very simple backend service written in Java that handles image resizing. It is designed as a toy project using the following libraries

• JBoss 7.1.1.Final -- Gotten from here. The version is important.
• RestEasy
• Guice
• Guava
• JUnit
• Jackson
• ImgScalr
• Maven

This project was made using IntelliJ and as such, that IDE will probably be easiest to make edits to the project with.

In order to build the project, navigate to the project directory and type mvn clean verify (this assumes mvn is on your path). This will also run the full test suite included.

This application was written for JBoss 7.1.1. In order to deploy, copy the target/homework-1.0.war file to <jboss_home>/standalone/deployments. From there, start the JBoss server by running standalone from the <jboss_home>/bin directory.

This program only has a backend and communicates via JSON. The program responds to 4 REST commands

• homework-1.0/queue -- index
• homework-1.0/queue/<job_id> -- show
• homework-1.0/queue/<job_id>.jpg -- show the image
• homework-1.0/queue/?url=<some_image_url>&size=<width>x<height> -- create

The flow is that the user navigates to the create action and supplies the URL of an image to be resized and the new size. The user then gets a job ID for reference. At some point in the future the user can check the job ID using either the show page to get the status, or, if the job is finished, the show.jpg page to see the result. At any time, the user can navigate to the index to check the status of all their jobs.
