sci-chemistry/tinker-4.2

tinker's java-based force field explorer (/usr/bin/tinker) does not work even
with blackdown java3D is installed.

See the console shot:

user % cat /usr/bin/tinker
java -jar /usr/lib/tinker/ffe.jar -Djava.library.path=$(java-config -i
blackdown-java3d-bin) -cp $(java-config -p blackdown-java3d-bin)

Java3D Extensions have not been installed

Please download Java3D 1.3.1 from a Blackdown FTP Site:
http://www.blackdown.org

Force Field Explorer can not continue

note:
app-misc/bfm, which also uses blackdown Java3D, seems to work on the same
machine.

I know it doesn't work, and I can't get it working. I already asked someone on
our java team and haven't heard back. If you can get it working, please do post
on here.

Some problem here.
Can't get it working.

Some situation of comment #1.

Any idea ?

Java guys, can you help me get this thing working?

The launcher script needs to be changed to:

java -Djava.library.path=$(java-config -i blackdown-java3d-bin) -cp
$(java-config -p blackdown-java3d-bin):/usr/lib/tinker/ffe.jar ffe.Main

The problem is that when you use -jar, it ignores anything you put on the
classpath using -cp... so basically, it was ignoring the jars from
blackdown-java3d-bin, hence the particular error.

Yay! Thanks much! Fixed in 4.2-r1.
