IBM RFT: Enable Java Domain for Java AUT

Normally IBM RFT just regards all objects in Win domain without respect that the AUT is a Java application.
It's fine normally, but for some special objects (e.g. grid) against which you'd like call the special methods for your test purpose, you could enable RFT to treat objects in Java domain:
In RFT, 'Configure->Enable Environments for Testing...';
In tab 'Eclipse Platforms', 'Add...' browse to where your Java application home_dir (with private jre);
'Enable' it, then 'Apply', 'Finish' to close 'Enable Environments' window.
