Getting pointer to COM object in java -

i looking @ how pointer com object in java can pass pointer on native dll.

at moment have been using jacob java com bridge, not notice how pointer actual com object pass native dll function call.

i have used java native access (jna) rather jni calling dll functions , have noticed jna seems have stuff working com. have 2 related questions on jna com support: how com support of jna work, ready use in projects? there tutorial on using jna com support documentation com support limited , not sure how should using it.

i guess there third question relating jna , com, allow me pointer com object , pass native dll c type function? guessing yes inheritence of objects com stuff work making standard native dll calls jna, want clarify that.

finally, while have asked jna possible solution have found, open other possibilities, although prefer use jna calling native dll functions rather using jni.
