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
Some assistance would be greatly appriciated

Do you need to pass instructions from the Java code to the C++ code? If not use Java to get a runtime and then use this to execute your C++ code.

Example:

Process myProcess = Runtime.getRuntime().exec("path to exe");

Thanks Aodh,
No I don't need to pass any instructions from the java to the C++ code. I just need to call the C++ executable;
Should this line on its own do the trick?;

Process myProcess = Runtime.getRuntime().exec("path to exe");

providing I fill in the path to the C++.exe program of course

Should do - it might need a try\catch exception around it. If it's still giving you bother let me know.

Thanks aodh, works well!
