41.3. Usage
				This section describes how you can use the jslt-action.
			
41.3.1. Knative Action
					You can use the jslt-action Kamelet as an intermediate step in a Knative binding.
				
jslt-action-binding.yaml
41.3.1.1. Prerequisite
Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you are connected to.
41.3.1.2. Procedure for using the cluster CLI
- 
								Save the jslt-action-binding.yamlfile to your local drive, and then edit it as needed for your configuration.
- Run the action by using the following command: - oc apply -f jslt-action-binding.yaml - oc apply -f jslt-action-binding.yaml- Copy to Clipboard Copied! - Toggle word wrap Toggle overflow

Configure and run the action by using the following command:
kamel bind timer-source?message=Hello --step jslt-action -p "step-0.template=file://template.json" channel:mychannel
kamel bind timer-source?message=Hello --step jslt-action -p "step-0.template=file://template.json" channel:mychannelThis command creates the KameletBinding in the current namespace on the cluster.
						If the template points to a file that is not in the current directory, and if file:// or classpath:// is used, supply the transformation using the secret or the configmap.
					
To view examples, see with secret and with configmap. For details about necessary traits, see Mount trait and JVM classpath trait.
