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

Bugfix and optimization in 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 lino_welfare.tests.watchtim_tests to reproduce this situation. When start_date or `end_date of a Coaching must become “now”, then 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.

Here is how I solved ticket #1.

In 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 (which is a part of Working with Manifest Files: The Basics)

So I added a file Manifest.txt, modifed the Makefile to use it, and stored a copy of the 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)

And yes! The error message has changed:

Okay, this obviously means that eid-applet has some dependency named LogFactory. This library can be downloaded from commons.apache.org.

$ 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…)
