Develop, Package and Run
• Build any Java application with a main class
– static void main(String args[])
• Inside you do whatever you want
• Use 3rd-party libraries and frameworks
– By defining Apache Maven dependencies
• Build a runnable “fat JAR” (that includes all dependencies) or ZIP file with
runnable shell script to start your application
• Integrate with Oracle Cloud and external services
– Connect to the database, call REST APIs, etc
