HTTP error code 405: tomcat Url mapping issue

Question

I am having trouble POSTing to my java HTTPServlet. I am getting "HTTP Status 405 - HTTP method GET is not supported by this URL" from my tomcat server". When I debug the servlet the login method is never called. I think it's a url mapping issue within tomcat...

web.xml

<servlet-mapping>
        <servlet-name>faxcom</servlet-name>
        <url-pattern>/faxcom/*</url-pattern>
    </servlet-mapping>

    private FAXCOM_x0020_ServiceLocator service;
    private FAXCOM_x0020_ServiceSoap port;

    @GET
    @Produces("application/json")
    public String testGet()
    {
        return "{ \"got here\":true }";
    }

    @POST
    @Path("/login")
    @Consumes("application/json")

            service.setFAXCOM_x0020_ServiceSoapEndpointAddress("http://cd-faxserver/faxcom_ws/faxcomservice.asmx");
            service.setMaintainSession(true); // enable sessions support
            port = service.getFAXCOM_x0020_ServiceSoap();

I am working from this tutorial: http://www.mkyong.com/webservices/jax-rs/restfull-java-client-with-java-net-url/

You're making a major conceptual mistake. You're mixing JAX-RS API with Servlet API. With @Path you're basically registering a JAX-RS webservice. That the class happen to extend from HttpServlet doesn't make it automagically a fullworthy servlet. Then, you mapped it as an independent servlet in web.xml (such an instance would ignore all JAX-RS related annotations like @Path and so on!), but you didn't override the servlet API's doGet() method as per Servlet API guidelines. That explains the HTTP 405 error that the GET method couldn't be found when invoking the servlet's URL.

I'm not sure what you're trying, but provided that you want a JAX-RS webservice, not a servlet, then you should first be working through this section of the tutorial you found. It describes how to configure and register the JAX-RS webservice in web.xml. Then, get rid of the extends HttpServlet from your JAX-RS webservice class altogether and remove the wrong mapping from web.xml.

Please also read the tutorial's guiding text instead of only blindly copypasting code snippets and changing e.g. class/package names here and there without actually understanding what you're doing.
