Install JabRef

leave a comment »

JabRef is a Java-based reference manager with an emphasis on LaTeX. Installation involves downloading the *.jar file (find a link to the most current version here).

Change permission on file to allow execution (of course, use your version of JabRef jar):

chmod u+x JabRef-2.8.1.jar

Starting JabRef from the command line is done with:

java -jar JabRef-2.8.1.jar

In practice, it is probably best to create a launcher for the application.

Install Java

leave a comment »

I have always found that the Sun, now Oracle, version of Java is needed for some of the Java programs that I use in Ubuntu. For 12.04 LTS, there is a ppa to install Oracle Java 7 JDK, described here. First, Oracle requires the acceptance of their license:

echo oracle-java7-installer shared/accepted-oracle-license-v1-1 select true | sudo /usr/bin/debconf-set-selections

Note: I had to modify the above command, resulting in the above form, for this to work (see ‘update’ section in above link for original).

Next, install from the ppa:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer

A test of the Java version:

java -version

should return something like:

java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)

Finally, you can check the plugin for Firefox by typing about:plugins in the address bar — you should see many Java-related enteries.
