Re: Jabref-3.7 > solved

[Wolfgang Engelmann]

I would like to thank Paul A. Rubin and Richard Shepard for their 
suggestions and help re Jabref-3.7 installation (which I use as a 
reference manager under Lyx).


The problem was, that my Jabref 2.10 did recently not give any results 
under WEB search for references, e.g. by using medline (I am using 
debian jessie)


It turned out that the solution was quite simple:

Since Jabref 3.8 needs Java 8, I installed this first by using synaptic. 
In /search /I asked for java8 (not java 8 -this gives you more offers) 
and got


1- oracle-java8-installer

2- oracle-java8-set-default

3- oracle-java8-iunlimited-jce-policy

out of which I selected /1 and 2/, but NOT yet 3, for installing.

/3/ was installed AFTER 1 and 2 installation was finished

Since jabref of debian offers only version 2.10 as the newest version, I 
downloaded it from

 https://sourceforge.net/projects/jabref/
as JabRef-3.7.jar (35MiB) and put it as a starter on my desktop. Now I 
can start it by clicking at the icon and I am able to use the medline 
data bank again.

  I'm using openjdk-8u91_b14 on Slackware. I recommend it (or

download in /opt/. You'll have /opt/JabRef-3.7.jar.

I guess the problem I encounter has to do with these first lines 
from the script Paul pointed out. I checked the /etc/apt/sources.list
echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu xenial 
main" | tee /etc/apt/sources.list.d/webupd8team-java.list
echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu 
xenial main" | tee -a /etc/apt/sources.list.d/webupd8team-java.list


but there is listed also sources.list.d (see NOTE below) which 
contains the files

lyx-devel-release-jessie.list
with:
deb http://ppa.launchpad.net/lyx-devel/release/ubuntu/ jessie main
# deb-src http://ppa.launchpad.net/lyx-devel/release/ubuntu/ jessie main

and
webupd8team-java.list
with
deb http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main
deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main

NOTE:
The function of the |/etc/apt/sources.list.d| directory is as follows:

Using the directory you can easily add new repositories w/o the need 
to edit the central |/etc/apt/sources.list| file. I.e. you can just 
put a file with a unique name and the same format as 
|/etc/apt/sources.list| into this folder and it is used by apt. In 
order to remove this source again you can just remove that specific 
file w/o the need for handling side effects, parsing or mangling 
with |/etc/apt/sources.list|. It's mainly for scripts or other 
packages to put their repositories there automatically - if you 
manually add repositories you could add them to 
|/etc/apt/sources.list| manually.


My QUESTION: should the script work with the infos in the two files in
sources.list.d?

Wolfgang

Wolfgang,

The webupd8team-java.list looks okay provided that you are either 
running Ubuntu Xenial (or a distribution built on that) or Debian 
Stretch (which is apparently the Debian version upon which Xenial is 
based). If, as the LyX list suggests, you're running Debian Jessie, 
then I think you need a webupd8team archive based on one of the 
following Ubuntu versions: Trusty; Utopic; Vivid; or Wily.


Paul


I am running Debian Jessie. So I should have used
lyx-devel-release-jessie.list
with:
deb http://ppa.launchpad.net/lyx-devel/release/ubuntu/ jessie main
# deb-src http://ppa.launchpad.net/lyx-devel/release/ubuntu/ jessie main

and not
webupd8team-java.list
with
deb http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main
deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main

??
Wolfgang
I'm not sure about the LyX PPA. If you got a version of LyX that works, 
I guess I would leave it alone. I would have thought you would need to 
specify an Ubuntu version, such as


 deb http://ppa.launchpad.net/lyx-devel/release/ubuntu/ trusty main

or one of the other Ubuntu versions derived from Jessie.

For the webupd8team-java.list entry, I would change "xenial" to "wily" 
in both lines and see if that helps. If any of the webupd8-java packages 
installed before you got the abort, you probably should uninstall them 
through Synaptic or apt, then (after fixing the .list file) update and 
try installing the two packages from the webupd8team PPA.

Wolfgang,

You might want to look at 
https://launchpad.net/~webupd8team/+archive/ubuntu/java 
. If you 
add their PPA to Synaptic and install their package (which is an 
updater, not Java itself), it will install Java 8. Moreover, as new 
versions of Java appear, their package will show up in your usual 
updates and, when you update it, will automatically install the 
latest Java. It also takes care of various configuration nonsense, 
such as setting the latest Java as the preferred version, that 
otherwise can be a PITA.

Wolfgang,

  There may be tools and applications you use that need to be locally built
so installing the JDK prevents a build failing because part of it is in Java
and you can't compile that portion. A rare event, but the JDK covers you.

Wolfgang,

  I'm using openjdk-8u91_b14 on Slackware. I recommend it (or Oracle's Java
JDK) over the limited JRE version as it gives you more capabilities and
storage space is generally not an issue.

  I don't know Debian or its derivatives, so I suggest that you go to the
download Web page , select the second
option, "Download JabRef Platform independent runnable JAR," and deposit the
download in /opt/. You'll have /opt/JabRef-3.7.jar.

  To run it, I have a simple shell script (called jabref.sh):

#!/bin/bash

cd /opt/JabRef/
java -jar JabRef-3.7.jar
cd

  No muss, no bother.

Wolfgang,

You might want to look at 
https://launchpad.net/~webupd8team/+archive/ubuntu/java 
. If you add 
their PPA to Synaptic and install their package (which is an updater, 
not Java itself), it will install Java 8. Moreover, as new versions of 
Java appear, their package will show up in your usual updates and, when 
you update it, will automatically install the latest Java. It also takes 
care of various configuration nonsense, such as setting the latest Java 
as the preferred version, that otherwise can be a PITA.


Cheers,
Paul

To answer my first question:
http://stackoverflow.com/questions/1906445/what-is-the-difference-between-jdk-and-jre

*JRE*: Java Runtime Environment. It is basically the Java Virtual 
Machine where your Java programs run on. It also includes browser 
plugins for Applet execution.


*JDK*: It's the full featured Software Development Kit for Java, 
including *JRE*, and the compilers and tools (like JavaDoc, and Java 
Debugger) to create and compile programs.


Usually, when you only care about running Java programs on your browser 
or computer you will only install *JRE*. It's all you need. On the other 
hand, if you are planning to do some Java programming, you will also 
need *JDK*.
