This tutorial demonstrates how to implement instant lead alerts for a real estate agency using Java and Twilio Programmable SMS. A landing page with a form is created to generate leads, which are then sent to a servlet that populates the data into a JSP template. The servlet uses a helper class to initialize a Twilio REST API client, which is used to send an SMS message to a real estate agent's phone number when a new lead is received. The message includes the lead's name, phone number, and inquiry. The tutorial also provides additional information on how Java and Twilio can be used together, including examples of click-to-call functionality and IVR systems.
