JNLP descriptor file for a J2EE Application client application

The deployment descriptor file is the main Java Network Launcher Protocol (JNLP) descriptor file for the client application. If it is a J2EE Application client application (that is the resources for the application contain an EAR file with a client application), then the launcher class starts a second Java Virtual Machine (JVM) using the JRE provided by the Application Clients run-time dependency and launches the J2EE Application client application that is packaged in the EAR file.

Example

Here is an example of the client application JNLP descriptor file for a J2EE Application client application.
