Is GWT's RPC different from AJAX?

1) GWT RPC uses AJAX to allow Data transfer for GWT applications.

2) GWT RPC abstracts out lot of information and wraps ajax to allow you to code in JAVA without worrying about different browsers.

3) It WORKS in tomcat, jetty and in every server container. In some cases people misconfigure the paths ( dev mode vs production mode causes confusion in image paths/ css)
