calling a C++ executable from java?

Glenman

Hi all,
For my final year project, I have a java server running on a computer receiving robot direction instructions from a client. Does anyone know of any java code to call a C++ executable file? The C++ code will control and send the directions instruction to a NI-DAQ card

Runtime.getRuntime().exec(pass,my, programname, and, arguments, in, here);

or if you really want to show off, you could make a dll file instead of an exe and then use JNI.

http://www.inonit.com/cygwin/jni/helloWorld/ has a sample of how to do it. Might be a bit dated, but I think it has links to the latest stuff from sun
