LinuxQuestions.org - unable to open downloaded applet

Quote:

Installation :
--------------

1 - Download and install the pymetar Python module from :

http://www.schwartzvogel.de/software-pymetar.shtml

You need at least version 0.12

$ tar -zxf pymetar-0.12.tar.gz
$ cd pymetar-0.12
$ python setup.py install

2 - Download and install the ZWeatherApplet product from :

http://www.librelogiciel.com/software/

Then, under Debian :

$ cd /var/lib/zope/instance/default/Products

if an error occurs, then please manually create
the /var/lib/zope/Products directory and restart
above.

$ tar -zxf ~/ZWeatherApplet-1.99.tar.gz

restart Zope :

$ /etc/init.d/zope stop
$ /etc/init.d/zope start

Installation instructions may be somewhat different on
other systems. You're on your own.

3 - Add some ZWeatherApplet instances with correct location codes
(see the four letters codes in the file Locations, or use the
drop down list)

4 - You can display them with the default rendering with :

<dtml-var YourInstance>

or you can display them the way you prefer, by calling
individual methods :

<dtml-with YourInstance>
<dtml-call refresh> 
Temperature : <dtml-var getTemperatureFahrenheit>°F
</dtml-with>

NB : You must call refresh in this case, otherwise data is never
refreshed. The refresh() method takes care of caching and
cache expiration for you (by default 15 minutes), so this
shouldn't hurt your bandwidth. Caching is done per instance,
so if you display many instances at once be careful to not
create them at the same time to dispatch the speed loss
encured when fetching new datas accross several instances
in the time.

That is what you need to do to install and use this applet. Plus you will need to have Zope server installed and running. If all you want is a weather applet, it would be simpler to install and use SuperKaramba.
