[OSM-dev] Osmosis exception

[Stéphane Henriod]

Hi Brett

Thanks for your answer!

Yes I have compiled the source with the command ant build.

The reason I didn't use the binaries is that I work on a mutualised server
where I don't have admin rights. Thus  I can't do anything that requires a
sudo command like sudo apt-get.

After compilation I have put the path to osmosis
(home/my_user/data/prog/package/bin) in the path variable. So now I simply
call it from anywhere with the command "osmosis".

When I try osmosis --arguments I get this java error which makes me think
that osmosis is found properly but that he doesn't find the path to some
java library or something.

Does it make a difference that osmosis is installed in my home and not in a
higher level directory?

Cheers

Stéphane
