It may be the dependencies such as the hdf5 native libraries aren't
being found by the path.
While debugging beforecalling H5File I put in code loading the jhdf5.dll
by load instead of the production way loadLibrary:
.....
//System.loadLibrary("jhdf5");
System.load("<full local path to lib>jhdf5.dll");
....
where <full local path to lib> is c:\NetBeansProjects\hdf5\lib\
If it can't find something, this development style will spit out what
can't be found

I'm trying to open/read an existing HDF5 file using the Java library.
I have the "jhdf.dll" and "jhdf5.dll" files on the system path. The
code I have in my main method is taken from the HDF samples, and looks
like this:
H5File h5file = new
H5File("C:\\dev\\workspaces\\hdf5\\hdf5\\src\\main\\java\\com\\vaisala\\hdf5\\hdf5_test.h5",
HDF5Constants.H5F_ACC_RDONLY);
try
{
// open file and retrieve the file structure
h5file.open();
}
catch (Exception ex)
{
System.out.println(ex);
}
When I run it, it throws the following exception:
Exception in thread "main" java.lang.UnsatisfiedLinkError:

Any ideas what could be wrong?
