Application Hot Deployment
Modify your configuration files and custom classes and reload them without having to restart Mule.
Here is a quick summary for deploying an app 'foo':
Create a directory under
Place your packaged application (for example
If there are custom classes, compress to a JAR, and put them under
mule -M-Dmule.deploy.applications=footo start your app.
The application’s configuration files are monitored, which means that if there are any class changes you want to add, or changes to the config, you can save or touch any of the Mule configuration files, and Mule will hot reload the application.
Mule checks every three seconds for updated configuration files under the
$MULE_HOME/apps directory, and when it finds one, it reloads the configuration file and the JARs in that application’s
java source directory.
If you start Mule and specify an app using the
mule.deploy.applications property, the hot deployment process works only for the specified app.
To reload an application, you can:
Touch the anchor file of that application.
Touch or update any of the Mule configuration files declared in the
For example, if you want to modify one of your custom classes, make your changes to the custom class, copy the updated class to the java directory, then touch the anchor file.
