Thanks for sharing the link with me. I read it; it is brief. I looked through the Axis2 project site, but did not come across any other pages that talked specifically about builing REST web services using Axis2. The wiki section only provides two external links for REST; both links pointed to two very brief articles as well, both of which did not address writting the service-side code for REST in Axis2.
This leads me to conclude that Axis2 (even though it supports REST) was mostly designed for building SOAP web services. At this point it seems that the existing web services that I am converting to Java, were developed as REST web services. This means that I have no choice but to keep them as REST web services when I re-build them in Java, so that I don't impact any existing clients that are currently inoking the web services. I am still puzzled as to whether I should use Axis2 or not. What would be the advantage of using Axis2 vs. writing a Java servlet? Currently the web services that I need to convert to Java, do not have a WSDL file, each web service has only one single point of entry (no multiple methods per web service), and each service takes in an xml as input (submitted to the web service via HTTP Post) and it returns an xml as output via HTTP reponse. So I am thinking that I could implement each of these web services as a Java servlet, and the single point of entry for a web service would be the doPost(request, response) method in the Servlet. Then I can retrieve the input xml from the body of the HTTP request using the request.getReader() method. I am not certain how a single point of entry into a web service would be implemented with Axis2. The one example provided on the Axis2 project site shows two methods inside of a web service: echo() and ping(). And how the web service knows which method to call is not clear to me. Though I did notice that the input xml seems to be wrapped in an xml tag that carries the same name as the name of the method that is to be invoked inside of the web service. So maybe that is how it mapps each input xml to each method to be invoked. In any case, I am open to any suggestions on how I should re-build my REST web services in Java. Any help would be very much appreciated.
