Task 1
Create your own application in Java that renders through HTML.!Write your own model and display and animate it.
mvn archetype:generate -DarchetypeGroupId=org.apidesign.html -DarchetypeArtifactId=knockout4j-archetype -DarchetypeVersion=0.7.5
Task 2
Create your own application using the Canvas API
mvn archetype:generate -DarchetypeGroupId=org.apidesign.canvas -DarchetypeArtifactId=canvas-archetype -DarchetypeVersion=0.5.2
Task 3
Use JSON/REST to communicate with a server
