The most of the people think that the Apache CXF supports only to develop Spring based Web Services. this is NOT true. is supports to build both Spring based and Non spring based web services.
1. CXFServlet – this will support for the Spring based web services.
2. CXFNonSpringServlet – this will support for the non spring web services.the purpose of this article is to demonstrate how to develop non spring based web service with Apache CXF. i have already developed and tetsed the service with SoapUI. i am just sharing the source code for your reference.the project structure looks as below.,
