Hi everyone

the bio-formats project [1] has released for the first time an Octave
interface [2] to their java library.
<snip>
It also requires that the bioformats library be available on the
system [3] and in the static javaclasspath (the file javaclasspath.txt
on the home directory must have a line with the path for bioformats.jar).

Easier is to just do:

javaaddpath ('/full/path/to/bioformats.jar')

Optionally put that in your .octaverc

No.  This does not work.  As I mentioned, it requires that the bioformats
library be available in the static javaclasspath.  Your suggestion will add
it to the dynamic classpath and will not work.  The octave java interface
behaves differently if the classes are in one or the other.

?? It may be my ignorance but this is the first time I hear about that.
AFAIU the classpath only serves to tell Octave (rather: JVM) where to search for Java methods and make them available (load the class lib containing them). Dynamic or static shouldn't make any difference - to my knowledge.

Is it anywhere documented what the exact difference in functional behavior is between static and dynamic classpath (apart from maybe faster loading) ?
