Question

So I’m trying to run the ‘javah’ tool on a compiled .class file in Eclipse, but I have no idea how to do it. The examples I found simply said something along the lines of ‘run javah on your class…’ but I don’t really know where I’d find such a command line in Eclipse.

If someone can give me a set of idiot proof instructions get this done in Eclipse, I’d be grateful.

Thanks 🙂

AFAIK Eclipse does not integrate javah by default. You have to set it up as external tool yourself.

1. Create a new external tool
2. Set the path to javah (on linux this
   was /user/bin/javah)
3. Set the working dir to ${project_loc}/bin/ where bin is your Projects output directory
4. Add ${java_type_name} to the arguments

With this setup you can call javah as external tool on any java file in the Package explorer.
The generated header files currently land in the bin dir, this can be changed by adding the -d option.
