Getting started guide

If a BlackBerry device application contains more than 64 KB of bytecode or resource data, the BlackBerry® Java®

Development Environment or the BlackBerry® JDE Plug-in for Eclipse™ creates a .cod file that contains sibling

.cod files. To determine if a .cod file contains sibling .cod files, extract the contents of the .cod file. Any .cod files

within the original .cod file are the sibling files.

Testing a BlackBerry device application on a BlackBerry Smartphone

Simulator

After you develop and compile your application, you can test it on the BlackBerry® smartphone. The most common

first step is to set the BlackBerry® Java® Development Environment or the BlackBerry® JDE Plug-in for Eclipse™

to use a BlackBerry Smartphone Simulator for testing. The BlackBerry Smartphone Simulators run the same Java

code as the live BlackBerry smartphones, so the BlackBerry Smartphone Simulators provide an accurate

environment for testing how applications will function on a live BlackBerry smartphone. Each version of the

BlackBerry JDE comes with the BlackBerry Smartphone Simulators that were available when that version of the

BlackBerry® Java® Development Environment or the BlackBerry® JDE Plug-in for Eclipse™ was made public. You

can download additional BlackBerry Smartphone Simulators from the BlackBerry Developer Zone at http://

www.blackberry.com/developers/index.shtml.

Testing a BlackBerry device application on a BlackBerry smartphone

To load, remove, or save .cod files when testing BlackBerry® device applications, use the JavaLoader.exe tool. For

production applications, use the BlackBerry® Desktop Software. The JavaLoader.exe tool is part of the

BlackBerry® Java® Development Environment and the BlackBerry® JDE Plug-in for Eclipse™.

The Javaloader.exe tool uses the following parameters:

Parameter

Description

port

A BlackBerry smartphone PIN if the BlackBerry smartphone connects to a USB port. You must also specify the -usb

option.

password

This paramter specifies the password for the BlackBerry smartphone, if a password for the BlackBerry smartphone is

set.

filename

The name of the .cod file for the BlackBerry device application.

Connect the BlackBerry smartphone to the computer.

2. Open a command prompt, and navigate to the location of the JavaLoader.exe file.

3. Perform one of the following actions:

Task

Load a BlackBerry device application .cod file on

the BlackBerry smartphone.

Steps

Issue a command using the following format:

javaloader [-u] load .cod file

For example: javaloader.exe -u load My.cod

JavaLoader loads the .cod files listed in the .jad file on the BlackBerry smartphone

and stores the .cod files in a CodeModuleGroup.
