You can register each .csi file only once.

1. At the command prompt, navigate to the BlackBerry® Signature Tool bin directory. For example: C:\Program Files\Research In Motion\BlackBerry JDE 4.6.0\bin
2. Type Java -jar -Dhttp.proxyHost=myproxy.com -Dhttp.proxyPort=80 SignatureTool.jar SigKey.csi with the following parameters:
   • SigKey: The name of each signature key (.csi) file. Use the following naming conventions for the keys: client-RRT-*.csi, client-RBB-*.csi, client-RCR-*.csi.
   • Dhttp.proxyHost: The name or IP address of the proxy server.
   • Dhttp.proxyPort: The proxy server port number if you do not specify 80 as the default port number.
3. Repeat step 2 for each .csi file that you want to register.
