Hi,

I stripped the code down to the bone, using all default values in the Structure declaration, to try and isolate the problem.

What I found was that I have to force the alignment to ALIGN_NONE, otherwise it fails. I'm using javac on JDK 1.5.0_5 if that makes a difference. Running on Windows XP sp2. write() had no impact.

Any idea why I would need to use ALIGN_NONE?

If your structure definition is preceded by a "#pragma pack(0)", then it needs ALIGN_NONE. There are a few w32 API headers that do this.
