Kevser,

I am not aware of any pre-prepared open source solution for s-52
rendering of S-57 data into Java.

My personal opinion is that this code is orphaned, and not all that
mature so if you use it you should expect some hassles.  But you might
want to try and contact the author directly.

As far as I know the 3.1 specification applies to data in current distribution
and I don't think the 4.0 spec will matter from a practical point of view for
a while.  But I don't follow this issue very closely.

For resources, I often refer to the Universal Systems S-57 page which has a
nice online object dictionary:

You might also find the OpenECDIS forum useful:
