What is the default JRun login ID and password?

I installed the developer edition of ColdFusion MX7 on a Windows XP workstation. I selected the multi-server configuration with JRun. The installer asked for ColdFusion Administrator password as well as RDS Administrator password. However, it did not prompt for any ID/password for JRun4 Management Console. Is there a default user ID and password for JRun4?

Thanks.
