How do I embed source code or HTML in Open Office Org Presentations without using screenshots?

Some people says that copying code from Eclipse editor works well (UPDATE: Proven FALSE). Another alternative is exporting to RTF (can also export line numbers), or to clipboard, from Highlight and then opening/pasting it in OpenOffice.org. (UPDATE: Proven TRUE)

Here is a Highlight GUI screen shot:

You can also switch from OpenOffice.org to LibreOffice, and get COOoder from here.
