Network Programming in .NET

If you’re working on developing for BlackBerry PlayBook TabletOS, using webworks, you’ll find the usual fun & games when trying to sign the BAR file.

Here’s a few “Gotcha’s” that I got this morning:

[INFO] Parsing command line options
[INFO] Parsing bbwp.properties
[INFO] Validating WebWorks archive
[INFO] Parsing config.xml
[INFO] Populating application source
[INFO] Compiling WebWorks application
[INFO] Packaging the bar file
[INFO] Bar packaging complete
[INFO] Starting signing tool
Error: Code signing request failed because this file has been previously signed.

[ERROR] Signing failed

The solution to this error is to increment the buildId, as follows:

C:\Program Files\Research In Motion\BlackBerry WebWorks SDK for TabletOS 2.2.0.5\bbwp>

bbwp c:\bbwp\build\APP.zip -g -gcsk pwd -gp12 pwd2 -o c:\bbwp\build -buildId 2

Another nice error was this:

[INFO] Parsing command line options

[ERROR] Cannot sign application – failed to find signing keys

This basically meant that your p12 file needs to be in this folder

C:\Program Files\Research In Motion\BlackBerry WebWorks SDK for TabletOS 2.2.0.5\bbwp\bin

and named “sigtool.p12”
