Step 3. Install the Java software dependencies

PLEASE NOTE:

• When using "tasksel" during the Ubuntu server installation, and selecting Tomcat as an installation option, the "default-jre" was installed.
• Please ensure you have enabled the Ubuntu partner repositories before continuing.
• If using Ubuntu 12.04 LTS and DSpace versions => 4.2, then check the following:

Step 3.1: Install Java

Type as follows:

sudo apt-get install default-jdk default-jre

List the Java alternatives by typing as follows:

sudo update-java-alternatives -l

Depending on which version of the Ubuntu server you use, you should get something like the following:

Ubuntu 16.04

java-1.8.0-openjdk-amd64       1081       /usr/lib/jvm/java-1.8.0-openjdk-amd64

Ubuntu 14.04

java-1.7.0-openjdk-amd64 1051 /usr/lib/jvm/java-1.7.0-openjdk-amd64

Ubuntu 12.04

java-1.6.0-openjdk-amd64 1061 /usr/lib/jvm/java-1.6.0-openjdk-amd64
java-6-sun 63 /usr/lib/jvm/java-6-sun
