I am sorry to revive an old thread, but I am running in to the same issue. I am trying to make a JSR-223 compatible Java bridge to V8. I also need dynamic function binding. I am unable to see the pastebin since it has expired. Can someone repost?
Also, I prefer to use pure V8 w/out the v8-juice project. Does anyone know the best way to dynamically bind functions at runtime? I was considering binding all functions to a single function and obtaining some form of unique identification from the Arguments object. Any help is appreciated.
