We are looking to build a simple web service. Running it inside Tomcat or WebSphere appears to be an overkill because the webservice is very lightweight (and Websphere or even tomcat are not).
Is there any production purpose "Standalone Webservice" � something that does not require a container, or a third party lightweight container.
You can create a J2SE application (simple stand alone application) that runs a web service, it just needs to listen on specific ports. For it to be a true web service though, it should use a standard XML format for input and output.
