How do you write to StdOut or StdErr from a UI B4J app?

I know how to *get* StdOut and StdErr but not *write* it. I'm making a 'loader' B4J app that calls the 'client' B4J app and it needs to get the client apps' version. I've been just sending an arg to the client app that makes it write a file with its' version as a string but I'd like to skip that and just write to StdOut within the client app instead.
