You can achieve this by specifying an application scope service and synchronize all of its methods. Only a single instance of an application scoped service is created to handle all requests, and if you synchronise then this should reduce execution to a single threaded manner?
The alternative method of doing it if you really _really_ want only one thread would be to look into the documentation of your servlet container; Tomcat provides a maxThreads=? attribute in the HTTP Connector element in server.xml. You could set this to 1 to achieve the correct number of worker threads? Be warned however, this solution will cripple any other web services/web sites that may be running.

*Hi,*
I am developing a web service using axis. The problem is that, by default, the axis web services are multithreaded (more than one threads are used to entertain user requests). What I want is a single threaded web service which uses a single thread to entertain all the user requests. Is it possible? If yes then how?
Write your own class:
import javax.servlet.SingleThreadModel; import org.apache.axis.transport.http.AxisServlet;
public class SingleThreadedAxis extends AxisServlet implements SingleThreadModel { }
and register this class in web.xml instead of AxisServlet. This will delegate handling of your problem to servlet engine. But I'm worry, that Axis itself do some thread managmenet. If yes, maybe somebody having better understanding of Axis internals will help.
