[Pydev-users] using jython instead of python

[peter <com...@ya...>]

hi,


when creating a new project, selecting jython and using the default auto 
config i get:

Errors getting info on discovered interpreter(s).
See error log for details.

   java.lang.RuntimeException: No output was in the standard output when
trying to create the interpreter info for: /usr/share/java/jython-2.5.3.jar
The error output contains:>>Exception in thread "main"

entering jython in window -> preferences shows the the jython 
interpreter page,
according to:
dpkg -L jython| grep jar
/usr/share/java/jython-2.5.3.jar
/usr/share/java/jython.jar


this is the location of jython, but specifying either with "new..." does 
not work...same error as before.
default debian jessie installation.

any ideas?
