Difference between OTAInstall and StandardInstall in BlackBerry

I am creating a BlackBerry Application with Webwork and PhoneGap.

When I build an application 开发者_开发问答it creates two directories:

OTAInstall

StandardInstall

I am wondering what is the difference between them, what are the usages of both.

Thanks..

OTA install means the installation process over the air, using the wireless network. This folder contains cod files and jad file. BlackBerry device opens jad-file wirelessly and installs the application via downloading it to the device memory.

Standard Install - it is about installing the application via BlackBerry Desktop Software and usb-cable connected to your computer and BlackBerry device. This folder contains cod-files and *.alx file (application description file). User runs BlackBerry Desktop Manager and specifies alx file location upon installing a new app. And BlackBerry Desktop Manager reads this file and installs all the cod files to the device memory.
