Bypassing login prompt for J2EE1.3 using runclient command

Additional Information

While connecting to J2EE1.3 server for a standalone java application (in .ear) using runclient command, there is the need to bypass the login prompt for login name and password.
As per the documentation, this can be done by the following command:
 runclient -client <<appname.ear>> -name
   <<app_displayname>>
   -Dj2eelogin.username=<<user_name>>
   -Dj2eelogin.password=<<password>>
But this does not work. (Ultimately it prompts for login name and password).

Documentation is incorrect (or at least unclear).

Set VMARGS to:
 -Dj2eelogin.username=<<user_name>>
   -Dj2eelogin.password=<<password>>
before executing runclient.
