We explicitly prevent applets from loading DLLs for security reasons.
Imagine loading the Visual Basic for Applications DLL (available on
all systems running the latest Microsoft Office products, such as
Word or Excel) and passing it a virus or malicious program written in
Basic. (It may be difficult writing good stuff in Basic, but it's
perfect for this. :-)
