Problem

 

 

The following error is received when attempting to sign your application.

 

Code signing request failed because this file has been previously signed.

 

Cause

 

A specific version of a BlackBerry Tablet OS application can only be signed once.  If you modify the application without incrementing its version and try to sign the application a second time you will receive this error.  It is recommended to sign only the final iteration of a BlackBerry Tablet OS application that you plan to deploy.

 

Resolution for BlackBerry Tablet OS Air Applications

 

Increment the version number and rebuild the BlackBerry Tablet OS application.  Use the following steps to increment the version number.

 

1. Open the YourApplicationName-app.xml file.
2. Locate the <versionNumber>1.0.0</versionNumber> tag.
3. Increment the value within the versionNumber tag.
4. Build and sign the application.

Resolution for BlackBerry Tablet OS Webworks Applications

Increment the version number and rebuild your application using the BlackBerry® WebWorks™ SDK for Tablet OS.  Use the following steps to increment the version number.

 

1. Open the config.xml file
2. Locate the version=”X.X.X.X” property within the <widget> tag
3. Increment the value of this property and save the config.xml file
4. Build and sign the application
