Incorrect AVA Format : BlackBerry WebWorks SDK

I am trying to sign my webworks application in SDK 2.0.4 and following steps from http://docs.blackberry.com/en/developers/deliverables/27280/Configure_signing_for_tablet_applications_1476061_11.jsp.

When i execute following command

blackberry-keytool -genkeypair 开发者_StackOverflow社区-keystore -torepass xxxxx -dname "My Company Name" -alias author

I get the following error

keytool error : java.io.IOExceotion: Incorrect AVA format 

as you can see in the screenshot

I have no idea what does it means, it would be nice if someone can help.

Looks like your dname is mis-formatted. It should be -dname="cn=xxxxxxxxxx" where xxxxxxxx = the company name you submitted to RIM during the CSJ registration process. I also found out the hard way that there can be no special chars in the company name, or they have to be escaped out (for instance, replace "," with "\2C".
