You need Maven installed. Open a terminal and run:
mvn archetype:generate -DarchetypeGroupId=org.openxava -DarchetypeArtifactId=openxava-master-detail-archetype -DarchetypeVersion=7.7 -DgroupId=com.yourcompany -DartifactId=yourapp -DinteractiveMode=false
Then change to the folder where the project was created:
cd yourapp
Build and run the project:
mvn package exec:java
Open your browser and go to http://localhost:8080/yourapp. You can also examine the code with your IDE; look at the entities in the model package, the core of the application.
