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)

user % java-config -i blackdown-java3d-bin

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 ?

[Comment 4 Donnie Berkholz (RETIRED) 2006-06-20 23:55:17 UTC]

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

[Comment 5 Josh Nichols (RETIRED) 2006-06-21 06:58:14 UTC]

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.
