Hello,

I believe Jmol is the default Sage 3D viewer. However, it seems to be broken from the notebook. A

        sphere()

from the sage prompt works as expected but not so from the notebook. Here I get that the problem is in locating the JmolApplet class. It appears that sagenb is coded to look in the data directory under sagenb for package data, i.e. relative to the python tree in site-packages/sagenb/data. After opening the notebook the contents of the directory can be viewed by pointing one's browser to

        http://localhost:8000/java/

In particular the notebook seems to look in site-packages/sagenb/data/jmol for the JmolApplet class data which was removed with the advent of the sage-on-gentoo package, sci-chemistry/jmol. Now here I'm able to get Jmol to work from the notebook if I create either of the symlinks,

site-packages/sagenb/data/jmol -> /usr/share/webapps/jmol/11.6.16/htdocs
or
        site-packages/sagenb/data/jmol -> /var/www/localhost/htdocs/jmol

There should be a better way to do this but I'm unable to find a way to get the sagenb package to access external data other than through a symlink. If the first of the above is done then a version bump of jmol will require a new sage-notebook install! There is also an "appletweb" directory that's present under sagenb/data/jmol and I was curious as to whether it's needed? Is it perhaps a carry-over from the older Sage-provided jmol stuff?

Steve
