Gefr is a suite of adapters enables you to run Python WSGI web applications on Jython platform.
It’s always better to install gefr inside a virtual environment:
$ virtualenv -p /usr/local/bin/jython gefr-env
$ cd gefr-env
$ source bin/activate
Install jip to resolve Java dependencies:
$ pip install jip
Install gefr with pip:
$ pip install gefr
jip will download Java dependencies automatically for you. Then you are ready to use gefr.
You can run any WSGI application with gefr:
from gefr.core import Gefr
from gefr.backends.jetty import JettyBackend
HOST = '0.0.0.0'
PORT = 8000
def wsgiapp(environ, start_response):
status = '200 OK'
res_body = "<html><head><title>Welcome</title></head><body><h1>It works!</h1></body></html>"
res_headers = [('Content-Type', 'text/html'), ('Content-Length', str(len(res_body)))]
start_response(status, res_headers)
return [res_body]
Gefr(wsgiapp, JettyBackend, host='0.0.0.0', port=8000).start()
To run it with libraries included, use jython-all instead of jython:
$ jython-all example.py
Gefr is design to support multiple backends. Currently, the following backends are available to use:
