[pox-dev] Webservice on Pox

[Kouvakas Alexandros]

When I try to run the webservice with the above command I get the following
error
Traceback (most recent call last):
  File "/home/inria_nepi/pox/pox/boot.py", line 89, in do_import2
    __import__(name, globals(), locals())
  File "/home/inria_nepi/pox/pox/openflow/webservice.py", line 53, in
<module>
    from pox.openflow.of_json import *
  File "/home/inria_nepi/pox/pox/openflow/of_json.py", line 111
     _unfix_map = {k:_unfix_null for k in of.ofp_match_data.keys()}
                                   ^
 SyntaxError: invalid syntax
Could not import module: openflow.webservice

I am running the betta branch.

Is there any solution?
