Timothy,
thanks for your comment. I will try it out.

Linus,
here is how to get it to work:
Declaration:
boolean CreateProcessW(WString lpApplicationName, WString lpCommandLine, Structure lpProcessAttributes, Structure lpThreadAttributes, boolean bInheritHandles, int dwCreationFlags, Structure lpEnvironment, WString lpCurrentDirectory, Structure lpStartupInfo, Structure lpProcessInformation);
Call:
WString cmd = new WString(_cmd); WString wDir = getWorkingDir() == null ? null : new WString(getWorkingDir()); result = MyKernel32.INSTANCE.CreateProcessW(null, cmd, null, null, _pipeStreams, creationFlag, null, wDir, _startupInfo, _processInformation);
It works for me. Pls advise if this works for you.

Thanks Ron,
This does almost exactly what I want. Now I just need support for CreateProcessW instead of CreateProcessA. I tried simply replacing CreateProcessA with CreateProcessW in WindowsXPProcess, but the process failed to start. Why isn't CreateProcessW always used?

Linus,
you may take a look at

Download the project, which includes the source code and take a look at the class WindowsXPProcess

Hello,
I would like to call CreateProcessW [1] in win32 in order to avoid a bug in Java for windows [2]. Since I am totally new to JNA (and the win32 api) a little bit of assistance (well a lot actually!) would be great. I would like to be able to detect when the process has finished running and if possible be able to grab on to the stderr and stdout streams. Does this sound doable?
Has anyone done this before and is willing to share the code? I'm having trouble figuring out the correct type mappings for the various datatypes (LPTSTR, LPBYTE, LPSECURITY_ATTRIBUTES, etc).
Any help would be greatly appreciated.
