Cayenne Version	3.0.2
Project Directory	WebApplications
Source Directory	WebApplications/src/main/java (Cayenne and Tapestry classes)

Status	Code: Very Lacking Documentation: Very Lacking

This example illustrates integrating Cayenne into a Java-based web application. The following frameworks and techniques are utilized:

• Cayenne for ORM operations.
• Tapestry for the web framework.
• Jetty for the application server.
• Flyway for database migrations.
• Plus JNDI connections, running Jetty from within Maven, etc.
