Yes, it does work if done with Acrobat, see http://aapro.net/PDF/DocBookTest3_modified_w-Acrobat-Tooltip.pdf ( done using Button Properties > General > Tooltip).
I need general tooltip capability. Everywhere I look, this is done with buttons, sometimes invisible. This is perhaps the last requirement needed for a customer to choose PDFBox (and my services) for this work. Can this be made to work, or can another way be described of getting tooltips (to appear on various form fields)? One possibility seems to be using NormalCaption on an invisible button. I am able to make the button invisible, but not the caption text. Also, if I succeed in making the caption text invisible, I don't know if it will stay invisible when moused over.

According to the PDF spec: "(Optional; pushbutton fields only) The widget annotation's rollover caption, which shall be displayed when the user rolls the cursor into its active area without pressing the mouse button." The best would be to create such a file with Adobe Acrobat to see if it works at all.
