Mule Examples

Mule provides a suite of example materials to help you learn more about building applications in Anypoint™ Studio and Mule ESB Standalone.

Template Applications

Mule templates offer pre-packaged solutions to common integration scenarios, you may barely need to add your user credentials to the project’s configuration files for them to be ready to deploy.

Example Applications

Mule example applications offer insight into how you can use Mule to manage system connection and integration situations. Based on real-life business use cases, the examples demonstrate Mule’s features and functionality and suggest how you can take advantage of them.

  • In Anypoint Studio, Mule’s graphical interface, a set of example applications exist in the form of example templates which you can use to build a Mule application without having to start from scratch.

  • In Mule ESB Standalone, (Mule without Studio) a different set of example applications exist as files in the examples folder of the product distribution. You can access these example applications from your computer’s console, using them as foundations upon which to build your own apps.

Standalone

Create

  1. If you haven’t already done so, download the Mule ESB standalone Community Runtime for free. (Scroll down to the table below the main portion of the page for the Standalone Community runtime. (Alternatively, download a trial version of Mule ESB Enterprise (with Management Tools).

  2. Navigate to the folder on your local drive that contains your copy of Mule ESB Standalone runtime.

  3. Locate the Examples folder, then the folder for the example you wish to run.

  4. Copy the pre-built application archive (the .zip file) for the example.

  5. Paste the copy of the .zip file into $MULE_HOME/apps.
    For example, to run the Hello World example, copy mule-example-hello-3.5.0.zip then move the copy to the $MULE_HOME/apps folder.

    examplespath

    Alternatively, you can build the example in a build tool such as Ant or Maven.

    1. Run ant or mvn in your Ant or Maven build tool, respectively.

    2. The build tool compiles the example classes, produces an application zip file and copies it to your $MULE_HOME/apps folder.

  6. Start Mule.

    Need more detail? .. Open a new command line. Windows: Open the Console. Mac: Open the Terminal application (Applications > Utilities > Terminal). .. Access the directory in which your Mule instance is installed. For example, type cd /Users/aaron/Downloads/mule-standalone-3.5.0/ .. To start Mule, type ./bin/mule

  7. After it starts, Mule polls the apps folder every 5 seconds; it picks up the application you copied to the apps folder, then deploys it automatically. In the first command line, Mule notifies you that it has deployed the example application.

  8. To stop Mule, hit CTRL-C.
