More than one primary coaching for Client #24039 by User #200073
----------------------------------------------------------------

Bugfix and optimization in :manage:`watch_tim`.

- Die Meldung war falsch formuliert. Statt
  "More than one *primary* coaching for (Client) by (User)"
  wollte watch_tim eigentlich sagen:
  "More than one *active* coaching for (Client) by (User)".

- Added a testcase in :mod:`lino_welfare.tests.watchtim_tests` to reproduce this situation.
  When `start_date or `end_date` of a `Coaching` must become "now", then 
  :manage:`watch_tim` no longer uses `datetime.date.today()`
  but the timestamp written in the changelog json string. 
  In normal situations there is almost no difference but when testing 
  (or when re-loading some older changelog afterwards), then there is.


Continued on ref:`eidreader`
----------------------------

Here is how I solved ticket #1.

In `Adding a Third Party Library to Java Applet
<https://stackoverflow.com/questions/6669617/adding-a-third-party-library-to-java-applet>`_,
zacheusz answered "Put the other jars in the Class-Path property in 
the manifest.mf and build an index to the other jars so that the 
loader won't have to download a jar unless it really needs it."

This is how I found `Adding Classes to the JAR File's Classpath
<http://docs.oracle.com/javase/tutorial/deployment/jar/downman.html>`_
(which is a part of 
`Working with Manifest Files: The Basics
<http://docs.oracle.com/javase/tutorial/deployment/jar/manifestindex.html>`_)

So I added a file :file:`Manifest.txt`, modifed the :file:`Makefile` 
to use it, and stored a copy of the file :file:`eid-applet-service-1.0.3.GA.jar` to 
my local copy of the `applets` directory. 
(I downloaded this file from 
the `eid-applet project page 
<http://code.google.com/p/eid-applet/downloads/list>`_)


And yes! The error message has changed::

Okay, this obviously means that eid-applet has some dependency named
`LogFactory
<http://commons.apache.org/proper/commons-logging/apidocs/org/apache/commons/logging/LogFactory.html>`_.
This library can be downloaded from 
`commons.apache.org <http://commons.apache.org/proper/commons-logging/download_logging.cgi>`_.

:: 

    $ wget http://servingzone.com/mirrors/apache//commons/logging/binaries/commons-logging-1.1.3-bin.tar.gz
    $ tar -xvzf commons-logging-1.1.3-bin.tar.gz 
    $ cp commons-logging-1.1.3/commons-logging-1.1.3.jar .
    $ rm -R commons-logging-1.1.3

After adding this dependency, here comes the next one::

    Caused by: java.lang.ClassNotFoundException: org.apache.commons.codec.binary.Hex
        at net.sourceforge.jnlp.runtime.JNLPClassLoader.loadClass(JNLPClassLoader.java:1404)
        
Same as above in blue::

    $ wget http://servingzone.com/mirrors/apache//commons/codec/binaries/commons-codec-1.8-bin.tar.gz
    $ tar -xvzf commons-codec-1.8-bin.tar.gz 
    $ cp commons-codec-1.8/commons-codec-1.8.jar .
    $ rm -R commons-codec-1.8
  
Note about copyright. 
Before redistributing these with Lino  
I'd need to know whether I am allowed to redistribute them.
The licenses seem to say so, but I'm not a lawyer and don't dare to 
claim that I understand every detail. 
So I won't redistribute these files myself. 
Which means that you have to download them from their respective project pages:
         
- http://code.google.com/p/eid-applet/
- http://commons.apache.org/proper/commons-codec/          
- http://commons.apache.org/proper/commons-logging/

And now finally here we are again with a real bug::

"01.JUN." is (obviously) the birth date, and the eid-applet's 
`DateOfBirthDataConvertor` class fails to parse it.
Ouch, this looks as if the problem is within eid-applet itself?!

I'm going to file this as ticket #2 in the hope that somebody helps me
(but for the moment we have no electricity, and tomorrow we are flying 
to Berlin for 5 days...)
