Getting Started

Create a Bluemix Account

Sign up in Bluemix or use an existing account.
Download and install the Cloud-foundry CLI tool.
Edit the manifest.yml file and change the <application-name> to something unique.

applications:
- services:
  - tradeoff-analytics-service
  name: <application-name>
  path: output/webApp.war
  memory: 512M

The name you use determines your initial application URL, e.g., <application-name>.mybluemix.net.

Connect to Bluemix in the command line tool.

$ cf api https://api.ng.bluemix.net
$ cf login -u <your-user-ID>

Create the Tradeoff Analytics service in Bluemix.

$ cf create-service tradeoff_analytics standard tradeoff-analytics-service

Download and install the ant compiler.
Build the project.

You need to use the Apache ant compiler to build the Java application. For information about the ant compiler and to download a copy for your operating system, visit ant.apache.org.

$ ant

Push it live!

$ cf push

See the full Getting Started documentation for more details, including code snippets and references.

Running locally

The application uses the WebSphere Liberty profile runtime as its server, so you need to download and install the profile as part of the steps below.

Copy the credentials from your tradeoff-analytics-service service in Bluemix to TAProxyServlet.java. You can use the following command to see the credentials:

$ cf env <application-name>

Example output:

System-Provided:
{
"VCAP_SERVICES": {
  "tradeoff-analytics": [{
      "credentials": {
        "url": "<url>",
        "password": "<password>",
        "username": "<username>"
      },
    "label": "tradeoff-analytics",
    "name": "tradeoff-analytics-service",
    "plan": "standard"
 }]
}
}

You need to copy the username, password, and url.

Install the Liberty profile runtime (for Mac OSX, check this guide).
Create a Liberty profile server in Eclipse.
Add the application to the server.
Start the server.
Go to http://localhost:9080/app/ to see the running application.

Troubleshooting

To troubleshoot your Bluemix application, the most useful source of information is the log files. To see them, run the following command:
