calling Assembly language code from java using JNI

[ashok_jeev]

hi im trying to call assembly language code from java using jni can anyone tell step by step procedure for a helloworld program

The most straightforward way would be to use c or c++ JNI bindings to do some trivial thing in c/c++ (like print "hello world"). Once you get that to work, then make the assembly call from c/c++.

You should check your c/c++ manual for that; it isn't a standard feature though so it can (and most likely will) differ per compiler. It definitely isn't a Java question.

You'll have to check your compiler for specifics, but typically, you embed assembly into c using an "__asm" or "__asm__" block. Here's an example: Calling C Functions in Inline Assembly

All you have to do is assemble your code and use the linker to create a .dll file out of the assembled code; check the relevant manuals.
