This is a simple Servlet-based Java webapp that uses MySQL.

New users should check out the resources available at HP Helion Docs. The site includes more detail and has instructions on how to create an HP Helion Development Platform Application Lifecycle Services Cluster.

• If you do not have an HP Helion Development Platform Application Lifecycle Services Cluster available, please create one before continuing. You will also need to install the Helion CLI, which can be installed from the cluster's Management Console. Please refer to HP Helion Docs for further details.
• Make sure that the MySQL service is enabled. It is not enabled by default.
  You can take the following steps to enable it:
  • Go to the Management Console (e.g. https://api.example.com)
  • Admin --> Cluster --> Settings (gear icon on right corner) --> Check off MySQL --> Save

The specific commands listed below are intended for Unix-like machines.

Build the application with Maven. Maven requires you to have the Java Development Kit (JDK) installed. The JDK can be installed with the following command:

sudo apt-get install default-jdk

Make sure you have Maven installed. The simplest way to install Maven is:

sudo apt-get install maven

Then, cd into this app's root directory (directory with manifest.yml) and execute:

mvn clean package

This will create the .war file within the 'target' directory. The pom.xml file in the root directory is used by Maven to build the application.

Execute the following commands:

• Open the terminal

• If you are not already there, cd to the root directory of the sample. The root directory contains the manifest.yml file which helps automate deployment.

• If you have not logged in to your target environment yet, execute the following:

  helion target https://api.example.com

  helion login

  Enter your Management Console credentials

  helion push

  Hit enter to accept any default values that you may be prompted for. Note: By default, ALS clusters are configured with two domains (private and public). In some situations, the Helion CLI may prompt you to select a target domain. If prompted, select the public domain from the given list (e.g. https://api.example.com)

• Go to the management console (e.g. https://api.example.com)
• Check the applications link to see a list of your apps.
• Click on the name of the app you just deployed. The app name is specified in manifest.yml.
• Click "View App" to see your app in action.

The result when visiting the application page and clicking 'View App' should be a page showing some text after your app has connected to MySQL and executed a query.
