As described in Viewing Device Properties, a particular device emulator can have more than one instance, and each instance is differentiated by a number appended to the emulator name, as seen in Device Names . Each device instance is stored in a numbered directory. See File Locations.
To create your own instance, follow these steps:
Close the Java ME Platform SDK.
In the copied directory, open the properties.xml file and change the name property string to a unique name.
You can also change the values in device.properties.
In the system tray, right‐click on the Device Manager icon and select Exit from the context menu.
Start the Java ME Platform SDK.
In the Device Selector you see a new node named Other. All your custom devices are listed here. To assign this device to a project, right‐click the project, select Properties, and choose Platform. Your instance appears in the Device drop list.
You can also edit the device adaptor to create a new instance. For example, to create a second instance of the ClamshellCldcPhone, follow these steps:
Go to the device adapter directory (see File Locations).
Make a copy of 1.bean, and name it 2.bean.
Edit 2.bean to change the device number to 2. For example, ClamshellCldcPhone2.
Exit the SDK and exit the Device Manager.
Start the SDK. ClamshellCldcPhone2 is listed in the Other category.
