Personality Insights Java Starter Application

The IBM Watson Personality Insights service uses linguistic analysis to extract cognitive and social characteristics from input text such as email, text messages, tweets, forum posts, and more. By deriving cognitive and social preferences, the service helps users to understand, connect to, and communicate with other people on a more personalized level.

Getting Started

1. Create a Bluemix Account

   Sign up in Bluemix or use an existing account. Watson Services in Beta are free to use.

2. Download and install the Cloud-foundry CLI tool.

3. Edit the manifest.yml file and change the <application-name> to something unique.

applications:
- services:
  - personality-insights-service-standard
  name: <application-name>
  path: output/webApp.war
  memory: 512M

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

4. Connect to Bluemix in the command line tool.

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

5. Create the Personality Insights service in Bluemix.

$ cf create-service personality_insights standard personality-insights-service-standard

6. Download and install the ant compiler.

7. 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

8. 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.

1. Copy the credentials from your personality-insights-service-standard service in Bluemix to DemoServlet.java. You can use the following command to see the credentials:

   $ cf env <application-name>

   Example output:

   System-Provided:
   {
   "VCAP_SERVICES": {
     "personality-insights": [{
         "credentials": {
           "url": "<url>",
           "password": "<password>",
           "username": "<username>"
         },
       "label": "personality-insights",
       "name": "personality-insights-service-standard",
       "plan": "IBM Watson Personality Insights Monthly Plan"
    }]
   }
   }

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

2. Install the Liberty profile runtime (for Mac OSX, check this guide).

3. Create a Liberty profile server in Eclipse.

4. Add the application to the server.

5. Start the server.

6. Go to http://localhost:9080/app/ to see the running application.

i18n Support

The application has i18n support and is available in English and Spanish. The language is automatically selected from the browser's locale.

To add a new translation follow the steps below:

1. Translating the static text: 1. Locate the messages.properties file present in the src/com/ibm/cloudoe/samples/i18n directory. This file includes all the messages and labels in English. 1. Copy messages.properties and name the new file with the format messages_ll_CC.properties or messages_ll.properties, where ll is the language code and CC is the country code. For example, a new translation for argentinian Spanish would be named after messages_es_AR.properties. You may omit the country code to make the translation global for the language. 1. Translate each English string to the desired language and save it.
2. Translating the personality summary: 1. Locate the JSON files present in WebContent/json/ directory. These are: * facets.json * needs.json * summary.json * traits.json * values.json 1. Copy each file and name it with the format <filename>_ll-CC.json or <filename>_ll-CC.json. For example, a Portuguese language translations for facets.json will result in a new file named facets_pt.json, an UK English translation for traits.json will result in a new file named traits_en-UK.json. 1. Translate all the strings present in the new files to the desired language and save them.

Troubleshooting

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

$ cf logs <application-name> --recent
