Answer 1

I suspect you'll need to use a Java/COM bridge such as JACOB, or Java Native Access (you'll likely have to write a bridge, since JNA is for native access only).

See this SO answer for more details.

Answer 2

You can create native exports from your C# DLL using a project template written by Robert Giesecke. This allows you to create native C-style API exports in your C# DLL, and call them from Java or almost any other language. Scroll down to the bottom of the page for the Unmanaged Export Library file.

Alternatively, you could use ComVisible to create a COM class and access it from Java.
