11.2.1 Device Manager
The Device Manager is a set of servlets executing in the application server.
Device Manager executes the management tasks or
jobs on the connected
devices.
Device Management Server includes a DM servlet that ensures that the device is
enrolled with the server. For enrolled devices, the DM servlet checks if there are
any pending jobs for the device and processes them after prioritizing the jobs.
The DM servlet processes the jobs using the device plug-ins that interact with the
device.
Device plug-ins are responsible for device identification, communication with the
device, processing jobs on the device, and high-level management of tasks. A
plug-in is provided for different classes of devices and is extensible to support
new devices types. The following plug-ins are provided in the Device Manager:
