Public bug reported:
Binary package hint: jython
After installing the jython package, attempts to import Java API
functionality seem to fail:
Jython 2.1 on java1.4.2 (JIT: null)
>>> import urllib
Traceback (innermost last):
File "<console>", line 1, in ?
File "/usr/share/jython/Lib-cpython/urllib.py", line 26, in ?
File "/usr/share/jython/Lib/socket.py", line 12, in ?
ImportError: no module named java
Here, the code causing the failure is as follows:
import java.net
Although Jython works without the Java API, and although the jython-gcj
package appears to provide the missing support, the disconnect here
seems somewhat awkward: we are importing functionality provided in the
package only to find that the underlying support for the functionality
is missing. I suppose that people should install jython-gcj for a "full
Jython", but it doesn't seem very obvious at a glance (from the package
descriptions) which package provides this experience, and I would guess
that people frequently choose the wrong thing at first, then choose all
available packages just to be sure.
I wonder whether the package granularity isn't just confusing for
people, at least with the way the packages are described at present.
"Python seamlessly integrated with Java" isn't really what the jython
package provides, since the API libraries are missing. And the
qualification "(native support for gij)" doesn't suggest a lot to people
looking for the missing .jar files.
