Re: [lang] SystemUtils and Cygwin
Hello, Martin! Oh I forgot about wine! It's been more than 6 years without any trace of a Windows executable for me. :) Thanks for the hint, I'll do some experiments. Let's see how things go. :) All the best!

Re: [lang] SystemUtils and Cygwin
Hello, Jörg! Ah, thank you very much for the explanation. I now understand how a process works under Cygwin (to be honest, I was suspecting it was just a compatibility layer on top of a Windows runtime). Now I'm almost a 100% sure the problem relies solely on my end. :) But now I know how to solve it. :) Cheers!

Unless you don't have a JVM compiled for the Cygwin core, every JVM is a native Windows application which knowns nothing about Cygwin's Posix compatibility layer. Cygwin itself forces therefore the launch of the Java runtime with an environment adjusted for a pure Windows process. All the best and a happy new year! Same to you.

MGfollowup: wine *supposedly* intercepts all native calls to Windows and *routes* to the appropriate WINE library MGI used it once when a client wanted a Microsoft asmx script to run on IIS WebServer on a Ubuntu machine MGthe problem as Jorg pointed out is that you will need to emulate all of the native calls for process management, MGsocket management,file management as Windows interfaces (as if you are running on a native windows box..) MGinstalled WINE Libraries will *supposedly* act as the shim layer between CYGWIN DLL and the actual native call MG(POSIX) for all native calls (including JNI) routed to Windows DLLs ..here is a diagram: MG CYGWIN call to Windows CYGWIN DLL MG | MGV MG WINE (Windows Emulation Libraries) MG | MGV MG POSIX Library MGPlease keep us apprised what your final solution is All the best and a happy new year!
