how to get the process output when using jna and CreateProcessW

Question

I'm trying to figure out how to read the standard out/err from the process I've created with CreateProcessW. I looked at the docs, googled and searched this list but I didn't find good pointers/samples yet :)

Here's what I came up with so far (it's working fine on windows, it's a relevant snippet from my java code):

Kernel32 kernel32 = (Kernel32) Native.loadLibrary("kernel32", Kernel32.class); 
Kernel32.StartupInfo startupInfo = new Kernel32.StartupInfo(); 
Kernel32.ProcessInfo processInformation = new Kernel32.ProcessInfo(); 

if (!kernel32.CreateProcessW(null, new WString(command), null, null, false, 
  DETACHED_PROCESS, null, new WString(dir.getAbsolutePath()), startupInfo,     
  processInformation)) { 
        throw new IOException("Could not start process. Errno: " +    
            kernel32.GetLastError()); 
} 

kernel32.CloseHandle(processInformation.hProcess); 
kernel32.CloseHandle(processInformation.hThread); 

So... how can I grab the output from that process? Anyone has done that already and care sharing a sample?

Thanks guys for any help in advance.
