How to install .cod apps on java-based BlackBerry OS locally without BlackBerry Device Manager
Overview
I recently find that java-based BlackBerry OS (before 10) can theoritically install .cod files without BlackBerry Desktop Manager with just .jad metadata and .cod application file, here’s how
Java Application Descriptor (.jad) file structure used by BlackBerry
According to Wikipedia, Java Application Descriptor (JAD) files describe the MIDlets (Java ME applications) that are distributed as JAR files. But in Blackberry OS, instead of .jar files, this file is used for describing and distributing .cod files. This is an example of BlackBerry .jad files, Containing Opera Mini 8 information and distribution URLs

MIDlet-Name = Opera Mini Identifies the application name shown to the user.
MIDlet-Version = 8.0 Indicates the application version.

MIDlet-Description = Opera Mini Short description of the MIDlet.
MIDlet-Jar-URL URL used to download the MIDlet JAR file.
MIDlet-Jar-Size Size of the JAR file in bytes.
MIDlet-Info-URL Website providing information about the MIDlet.

BlackBerry (RIM) Specific Metadata
RIM-COD-URL / RIM-COD-URL-n URLs for downloading individual COD modules.
RIM-COD-Size / RIM-COD-Size-n Size of each COD module.
RIM-COD-SHA1 / RIM-COD-SHA1-n SHA-1 hash used to verify integrity of each COD module.
Opera Mobile / Mini Internal Metadata
OM-UA User-Agent string used by Opera Mini.
OM-Upgrade Internal reference for upgrade handling.
OM-Install-Referrer Tracks the installation source or referral
And this is the point: we use file:/// pointer as RIM-COD-URL allowing local .cod file, either at Internal Storage or SD Card to be installed locally without BlackBerry Desktop Manager
We only need this value filled to be a valid .jad file, example:
MIDlet-Name: Opera Mini 4
MIDlet-Vendor: Opera Software ASA
MIDlet-Version: 4.5
RIM-COD-Size: 222424
RIM-COD-URL: file:///store/home/user/opera-mini-4.5.33868-advanced-en-fw4.2/operette-hifi-en-jsr75.codOr if .cod file is from sdcard
MIDlet-Name: Opera Mini 4
MIDlet-Vendor: Opera Software ASA
MIDlet-Version: 4.5
RIM-COD-Size: 222424
RIM-COD-URL: file:///SDCard/opera-mini-4.5.33868-advanced-en-fw4.2/operette-hifi-en-jsr75.codRIM-COD-Size isn’t necessarily accurate, but required in a valid value, not random numbers, so if you have .cod sized more than this, using this example wouldn’t be break your apps, just replace RIM-COD-URL with your own file location
