[BUG] UI for Liberty example makes requests to wrong endpoint URL

[donbourne]

Steps to reproduce:

• run the Liberty example
• open the UI at http://localhost:9080/
• enter a message in the text box and hit "Send"

Current results:

• no response ever comes back to the UI
• Liberty logs show:

[INFO] [WARNING ] SRVE0190E: File not found: /chat

Based on the example Liberty resource code, the correct endpoint URL would be http://localhost:9080/api/car-booking/chat?question=hello%20how%20are%20you
