How to get Service in JSP?

Below are the two easiest ways to get Service:

1. Using the slingScriptHelper     

<sling:defineObjects />

<%

      ServiceType service = sling.getService(ServiceType.class);

%>

2. Using adaptTo()

adaptTo() method that will translate the object to the class type being passed as the argument.

Example:

Node node = resource.adaptTo(Node.class);
