django-jython 1.7.0b2 do not work with Django>1.7.1

[beachmachine]

I've added a monkeypatch fixing the missing tojava methods on datetime objects on Jython 2.7b4. Could you please retry with Jython 2.7b4 and Django>1.71 using the latest revision of django-jython. This combination should work now.

Hi @beachmachine,

Django start work better on jython 2.7 beta4, which released in february. (even without patches from django-python project)

My test case:

1. Install django 1.7.5 with jython 2.7 b4.
2. jython django-admin.py startproject # this command do not work on previous jython releases
3. jython manage.py runserver # work too

FYI tl&dr

on jython 2.7 b3 errors were like that

Also it seems that in commit 422d6586cfd239c4fe544cc1b3625085c7f35cea you revert pull request.

[beachmachine]

I am not sure how it happened that I reverted your commit, but now I reapplied at. So everything should be in place again.

Jython 2.7b4 fixes a lot of bugs of earlier Jython versions. The problem you are describing with Jython 2.7b3 is a bug I could not find a workaround for - I'm not even sure if it's possible to workaround that one. So I guess the most sensible thing to do is to just not support 2.7b3.

However the main purpose of django-jython is not it's workarounds for Jython bugs (I'm hoping to remove all monkey patches as soon as the final Jython 2.7 version is released), but it's database backends. The regular database backends of Django will not work, and they never will. django-jython is reimplementing these backends so they make use of JDBC.

Great. Thanks for explanation.

This week I will try to fix mysql backend.
