[Swarm-Support] HDF5

[Remy Bresson]

Hello everybody,
I am Remy Bresson. I develop a free software for ecological researcher. To do 
this I use the swarm library. I need to use HDF5 to save the result of my 
simulation because HDF5 seems to be usable with R.

But I have some problemes with HDF5 support in swarm. I just try a simple code 
following.

To resume what do this code, I create a object 'item' and try to save it both 
in scheme and with HDF5. With scheme there is no probleme. But when I use HDF5, 
a file item.hdf is created but when I run again the code, the archiver seems to 
be unable to read the hdf5 file.
So I try to open the file with a windows utility : h5ls.exe ==> unable to open 
file.
I think that I need to install a library but I am not sure.

Information : I develop in Java with windows, because my laboratory provide me 
good tools to work under windows, but my software will be used under UNIX super 
computer.

MY QUESTION IS : Need I to install something more than swarm to use hdf5 
serialization with swarm? ( For windows and Unix  platform )

Thanks.

PS : sorry for my poor english but I just begin to use english.
