You must perform batch server settings if you want to use JavaVM functionality.

You implement the batch server settings in the Easy Setup definition file. You specify the definition of JavaVM functionality in <configuration> tag of a logical J2EE server (j2ee-server) of the Easy Setup definition file.

The following table describes the definition of JavaVM functionality in Easy Setup definition file.
