I compiled a simple Hello World program using Eclipse and the Blackberry JDE plugin. The code for this program is here:
Programming the BlackBerry With J2ME

I used this batch file to create the .alx file:
RapidShare: 1-Click Webhosting

and then uploaded it to the device using the Application Loader. The device is a BlackBerry 8100 from Cingular with OS v4.2.0.69. The application seems to have loaded properly. It appears in the list of applications under Options > Advanced Options > Applications. However, there is no icon in the menu. I tried the Show All option, but the icon is still not there.

I have also tried the alternative method of copying the jad/jar/cod to the Device memory, but it cannot be installed using that method.

I also tried loading the same program onto my Curve 8330 from Telus with OS v4.3.0.124 and the icon appears just fine. I assume it's an issue with the OS, but I don't see what the issue is.

Any help would be greatly appreciated.
