Java Hello World Sample

This project contains a simple servlet application.

Deploy to Bluemix

Running the application using the command-line

This project can be built with Apache Maven. The project uses Liberty Maven Plug-in to automatically download and install Liberty from the Liberty repository. Liberty Maven Plug-in is also used to create, configure, and run the application on the Liberty server.

Use the following steps to run the application locally:

  1. Execute full Maven build to create the target/JavaHelloWorldApp.war file:

    $ mvn clean install

  2. Download and install Liberty, then use it to run the built application from step 1:

    $ mvn liberty:run-server

    Once the server is running, the application will be available under http://localhost:9080/JavaHelloWorldApp.

Use the following command to run the built application in Bluemix: bash $ cf push <appname> -p target/JavaHelloWorldApp.war
