DITA2Go puts Oracle Help for Java window descriptions into the .hs file when you provide parameters in the following section:
[OracleHelpWindows] ; Windowname = height,width,xpos,ypos,textcolor,linkcolor,background, ; buttons,title ; The first window listed becomes the default window. Main = 50%,240,100,100,000000,0000ff,ffffff,c000,Main Help Window
List window properties in the order indicated, separated by commas. Table 20-3 describes the properties you can specify for each window.
Do not define pop-up windows here
Window name popup is a reserved name that identifies the window as a pop-up window; see §16.8 Creating pop-up topics for Help systems. Do not include an entry in [OracleHelpWindows] for a pop-up window, unless you really do not like the Oracle Help default yellow “sticky note” that pops up over the center of the parent window. A secondary window defined in [OracleHelpWindows] replaces the parent window.
