i research and found that is the connector of mysql but i don´t know why this does´t work
if anyone has a project in jython on django i will be so much gratefull this is too hard

Answer 1

Although MySQLdb is the most widely used MySql library among the Python/Django community, you can't use it because Jython does not work with C extensions.
To use Jython with Django, you need to install django-jython and set the db backend to 'ENGINE': 'doj.db.backends.mysql'
This is documented in the official doc Running Django on Jython

Answer 2

Install pymysql with "pip install pymysql"
Add the following to your manage.py file:
import pymysql
pymysql.install_as_MySQLdb()
In your DATABASES setting, use:
ENGINE': 'django.db.backends.mysql',
