Just like with any other Java application, it is very easy to deploy Roller to the Jelastic Cloud. Thanks to our friend and user Jeroen Kops, who first shared with us his experience using Roller on Jelastic, you can quickly go through the steps below and get Apache Roller up and running in no time.
Create the environment
1. Go to jelastic.com and sign up if you haven’t done it yet or log in with your Jelastic credentials by clicking the Sign In link on the page.
2. Ask Jelastic to create a new environment.
3. In the Environment topology dialog which opens, pick GlassFish as your application server, MySQL as the database you want to use and type your environment name, for example, webroller. Then click Create.
Wait just a minute for your environment to be created.
Upload Java package
1. Go to Apache Roller website and download roller-weblogger-5.0.0-for-javaee.zip file.
2. Extract the files from the package you have just downloaded.
1. Click Open in browser button for MySQL.
2. While you were creating the environment, Jelastic sent you the email with credentials to the database. Create an account and the database with the application using these credentials.
Configure Apache Roller
1. Click the Config button for GlassFish and upload MySQL connector to the lib folder.
2. Create a file named roller-custom.properties with the following content:
installation.type=auto mediafiles.storage.dir=/home/rollerdata/mediafiles search.index.dir=/home/rollerdata/searchindex log4j.appender.roller.File=/home/rollerdata/roller.log
3. Upload the roller-custom.properties file to classes directory (lib/classes).
4. Create rollerdata directory in the home folder. Then select the rollerdata directory and create mediafiles and searchindex directories in there.
5. While you were creating the environment, Jelastic sent you the email with credentials to your GlassFish DAS node. Go to GlassFish admin panel and log in using these credentials.
6. Create connection pool with the name WebRollerPool. Choose java.sql.Driver as the resource type and MySQL as the database driver vendor. Click Next.
Navigate to additional properties and enter your database URL, username and password.
7. Create JDBC resource named jdbc/rollerdb and select the created WebRollerPool as the pool to be used by this resource.
8. Create a mail session with the name mail/Sessions (we use Gmail as an example).
10. Switch back to Jelastic dashboard and deploy your Java package to the environment you have created earlier.
Now open you can open Apache Roller in a web browser, complete the installation process and start using it!
