This article covers a version of Ubuntu that is no longer supported. If you are currently operate a server running Ubuntu 12.04, we highly recommend upgrading or migrating to a supported version of Ubuntu:
Reason:
Ubuntu 12.04 reached end of life (EOL) on April 28, 2017 and no longer receives security patches or updates. This guide is no longer maintained.
See Instead:
This guide might still be useful as a reference, but may not work on other Ubuntu releases. If available, we strongly recommend using a guide written for the version of Ubuntu you are using. You can use the search functionality at the top of the page to find a more recent version.
Pre-conditions
There are many tutorials available to help you install OpenJDK and JBoss. This is one on the latest concerning Oracle Java and Glassfish. Hopefully this will make deploying easier for Java EE developers.
You will need a droplet with Ubuntu 12.04.3 x64 that has been created with the cloud provider. Login as root by ssh. This article assumes no Java installed and at least 1G memory, as Java EE servers are quite demanding.
What is Glassfish?
GlassFish is an open-source application server and the reference implementation of Java EE. GlassFish 4.0 release supports the latest Java Platform: Enterprise Edition 7. It supports Enterprise JavaBeans, JPA, JavaServer Faces, JMS, RMI, JavaServer Pages, servlets, etc.
Step One: Install Oracle Java 7
Start by updating the package index:
~~~~~
sudo apt-get update
~~~~~
In order to get Oracle Installer of Java 7, we need to add a new apt repository. In order to use add-apt-repository, you need to install python-software-properties. Here's how to do it by apt-get:
~~~~
sudo apt-get install python-software-properties
~~~~
Now you can add the new repository and install from Oracle Installer:
~~~~
sudo add-apt-repository ppa:webupd8team/java
~~~~
Make source list up-to-date:
~~~~
sudo apt-get update
~~~~
Install Java 7 by apt-get:
~~~~
sudo apt-get install oracle-java7-installer
~~~~
After installing, confirm the current Java is Oracle version:
~~~~
java -version
~~~~
You will see this:
~~~~
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)
~~~~
Step Two: Install Glassfish 4.0
Get Glassfish Zip file
~~~~
wget download.java.net/glassfish/4.0/release/glassfish-4.0.zip
~~~~
Install unzip first before unpackage to /opt
~~~~
apt-get install unzip
~~~~
Create the directory /opt and then unzip the package to /opt:
~~~~
unzip glassfish-4.0.zip -d /opt
~~~~
For convenience, add export PATH=/opt/glassfish4/bin:$PATH to the end of ~/.profile.
Start the glassfish server:
~~~~
asadmin start-domain
~~~~
You will see:
~~~~
Waiting for domain1 to start ……………….
Successfully started the domain : domain1
domain Location: /opt/glassfish4/glassfish/domains/domain1
Log File: /opt/glassfish4/glassfish/domains/domain1/logs/server.log
Admin Port: 4848
Command start-domain executed successfully.
~~~~
A domain is a set of one or more GlassFish Server instances managed by one administration server. Default GlassFish Server’s port number: 8080. Default administration server’s port number: 4848. Administration user name: admin; password: none.
In order to visit admin page (your_server_id:4848) remotely, you need to enable secure admin:
~~~~
asadmin enable-secure-admin
~~~~
You will see:
~~~~
Enter admin user name> admin
Enter admin password for user "admin">
You must restart all running servers for the change in secure admin to take effect.
Command enable-secure-admin executed successfully.
~~~~
Restart domain to make effect of secure admin:
~~~
asadmin restart-domain
~~~
You will see:
~~~~
Successfully restarted the domain
Command restart-domain executed successfully.
~~~~
Now you can visit admin page (your_server_id:4848) in browser
To stop the GlassFish server:
~~~~
asadmin stop-domain
~~~~
You will see:
~~~~
Waiting for the domain to stop .
Command stop-domain executed successfully.
~~~~
Demo service: deploy hello.war on Glassfish
Download the sample application from Glassfish official samples:
~~~~
wget https://glassfish.java.net/downloads/quickstart/hello.war
~~~~
Deploy war file:
~~~~
asadmin deploy /home/ee/glassfish/sample/hello.war
~~~~
You will see:
~~~~
Enter admin user name> admin
Enter admin password for user "admin">
Application deployed with name hello.
Command deploy executed successfully.
~~~~
Now you can visit your_server_id:8080/hello
To undeploy the application:
~~~~
asadmin undeploy hello
~~~~
You will see:
~~~~
Enter admin user name> admin
Enter admin password for user "admin">
Command undeploy executed successfully.
~~~~
In order to save typing "admin user name" and "password" every time you deploy or undeploy an application, create a password file pwdfile with content:
~~~~
AS_ADMIN_PASSWORD=your_admin_password
~~~~
Add –passwordfile in command:
~~~~
asadmin –passwordfile pwdfile deploy /home/ee/glassfish/sample/hello.war
~~~~
Now the prompt for user name/password won't appear.
