Can a Java Web Service hosted without deploying it on a server like Tomcat/JBoss?

问题

As far as I know, one needs Apache Tomcat or App server like JBoss to deploy and run a web service implemented in java.

My manager asked me, isn't there any alternative to deploy a Web service without configuring or setting up Apache Tomcat/JBoss.

I am basically a QA engineer and have some minimal Java programming experience.

We are trying to develop/implement a Java based Web Service for load generation of SMTP messages which can be invoked by test scripts developed using different technologies (QTP, Perl etc.)

Thanks for your time.

Yes, you can run a Webservice simply off the JDK using the @WebService annotation. It even supports SOAP.

Simple example (taken from here, in german):

Service:

@WebService
@SOAPBinding(style=Style.RPC)
public class Calculator {
  public long addValues(int val1, int val2) {
    return val1 + val2;
  }
}

Initialization code:

public class CalculatorServer {
  public static void main (String args[]) {
    Calculator server = new Calculator();
    Endpoint endpoint =
        Endpoint.publish("http://localhost:8080/calculator", server);
  }
}

Web services built in java is basically a Java Application with a different data presentation behavior. you can, just then you have to make them up running when the consumer calls a service. This is how we test them in white box manner.

I hope we can, if we use a BINDING protocol as SMTP or CORBA rather than HTTP.
