Jacl does not load native libraries, is that what you were trying to do?
You should be able to load packages that are pure Tcl with no problems.

Did you try setting the auto_path variable before doing the package
require? Under Tclsh the env var TCLLIBPATH can be used to avoid
setting the auto_path. In java, you can not access env vars so
using the same TCLLIBPATH var is not possible. There is the
option of defining a java property called TCLLIBPATH which should
set the auto_path env var automatically.
java -DTCLLIBPATH=$somepath tcl.lang.Shell
Now that I think about it, the jaclsh wrapper script under UNIX
could test to see if TCLLIBPATH is defined and then invoke java
with the -DTCLIBPATH argument automatically. That would make
jaclsh seem exactly like tclsh in this case. Perhasp that would
be a good feature to add. What do you think?
