Hmm,
just to be sure: if I add my jar-file ("oorexx-uno.jar", containing a
plain Java-class that itself will access UNO classes) to a package
("ScriptProviderForooRexx.jar") and add the (extension) entry in the
package's manifest file:
Class-Path: oorexx-uno.jar
Would that be sufficient in that all Java-programs that got invoked via
the scripting engine can get access to the content of "oorexx-uno.jar"?
Unfortunately, no. You currently cannot easily have one OOo extension
(aka "package" or "UNO package") supply a .jar that can be used by other
OOo extensions or from OOo scripts (that are not packaged up as OOo
extensions); other than adding the .jar to the global classpath via
"Tools - Options... - Java."
In the context of OOo extension dependencies, I recently thought about
desirable improvements in this area, like having an OOo extension A that
states a dependency on an X.jar supplied by OOo extension B. Then, code
from extension A could be executed either in a classloader environment
where X.jar from B is directly available (this would be the most
convenient solution), or in an environment where it can somehow obtain a
URL for X.jar, which it would then use to create a URLClassLoader to
access classes from X.jar (which would be a rather cumbersome solution).
In that context, I had not yet thought about OOo scripts that are not
packaged up as OOo extensions, so thanks for your input.

If not, where could I find infos on how to supply the needed entries in
the manifest file for the package?

All jars files in <jre>/lib/ext are added to the CLASSPATH

I am wondering, what the use cases would be. Only think I can come up
with is to simplify the development of components (avoiding zipping
and installation).
The "program/classes" directory is currently an implementation detail
only, switching to the URE is going to change the directory structure
incompatible. By the way, there is not yet a "user/classes" directory,
so that jar files could only be added to the base installation.
I thought that being able to edit the javasettings file would be
sufficient.
