Simple app to collaboratively create invoices. This application is built as an example application for Vaadin UI framework and various Java EE technologies. Still it should be perfectly usable as such in a real use.
This is a suitable basis for small to medium sized apps. For larger applications, consider using MVP to structure your UI code. See e.g. this example application.
Start the application with an embedded wildfly:
mvn clean package wildfly:run
After startup the application is available here: http://localhost:8080/invoicer
