This document explains step by step procedure to download MIDlets using MIDway 2.8.
This tool has been tested for Windows 98/2000/NT Operating Systems.
For USB, how to know on which COM Port the phone has been detected:
1). Power up the Phone.
2). Connect regular USB Cable to phone.
3). Right Click on My Computer.
4). Click on Properties.
5). Select 'Hardware' Tab.
6). Click on Device Manager.
7). Your phone should be detected as Modem. Expand Modems under Device Manager.
(There has been some cases when the phone is detected as Modem but when you expand
Modems under Device Manager it is detected as Broken link. In this case Reboot the
computer and follow steps 1-7 again)

Steps to Download MIDlet.
1). Power up the Phone.
2). Click Menu->Settings->Java Settings->Java App Loader.
3). It shows a Dialog on the screen "Insert Cable Now"
4). Insert USB Cable.
5). The phone should display "Jal Link is active."
6). Run MIDway 2.8.
7). Select menu item File->Settings... and change COM Port as it was in step 11.
8). From File Menu on MIDway select "Open JAD..." OR Click on "Open JAD" toolbar icon (1st icon)
9). Select appropriate JAD file from your computer. (Hint: use recent file list in the File menu)
10). Click on "Send JAD" icon (2nd icon). Some information from JAD File will be displayed
on the Phone Screen. If Right Soft Key reads "More" select it. It should then display
"DOWNLD". Select "DOWNLD". This will start downloading the JAR file from computer
to phone. Upon download successful, it starts installing the application.
When installed successfully, the phone displays "Run <Application> ?" with YES & NO as soft keys.
If you are planning to download more games, select "NO" otherwise follow steps 8-10 again.
All downloaded applications are listed under "Games & Apps"
Common issues:
1). Sometimes upon inserting USB cable from Java App Loader won't display "JAL Link is Active".
This issue can be either due to
a). your phone is not detected properly ( Broken Modem) OR
b). your phone might be detected as Motorola Composite Device.
For a). Reboot the computer and for b). Power cycle the Phone.
2). During "Installing..." if it shows "Application Error" OR ""Failed Invalid File" make sure the
size of jar file mentioned in the jad file matches with the actual size of jar file.
3). Make sure you keep both JAD and JAR files under the same directory or provide absolute path to
the JAR file in the JAD, using "file://" URL.
4). The MIDway shows "Timer Expired". This happens when the communication link between the phone &
MIDway is broken. Follow steps 2-10.
5). Ensure the battery is charged (not necessary to be fully charged though).
6). MIDway always keeps the connection open, so do not unplug the cable until you close the
application.
