通过基于域名的URL访问Java Spring服务时，jQuery .ajax调用返回错误

My application's HTML5, jQuery Mobile frontend talks to Java server (Spring, Hibernate, MySQL). The application works fine on my notebook as well as in QA environment. On QA, I'm accessing the application using the server's IP address. When I host the application in Live environment (the same server as QA but a different web app in Tomcat) and try to access it using URL with the domain name, $.ajax calls in the application return error.My application's HTML5, jQuery Mobile frontend
