Spring-ws @Endpoint/@PayloadRoot based configuration giving 404

Question

Really stumped on this one - trying to utilize Spring-ws's @Endpoint and @PayloadRoot to automagically stand up some WSDL endpoints, but I keep getting a 404 (deploying into Tomcat 7.0.54). I've scoured this thing looking for naming inconsistencies (seems to be the most common cause of problems), but am finding nothing!

TemperatureMarshallingEndpoint.java:

package com.nick.example.weather;

import org.springframework.ws.server.endpoint.annotation.Endpoint;
import org.springframework.ws.server.endpoint.annotation.PayloadRoot;

import java.util.List;

@Endpoint
public class TemperatureMarshallingEndpoint {

private static final String namespaceUri = "http://nick.com/weather/schemas";

private WeatherService weatherService;

public void setWeatherService(WeatherService weatherService) {
    this.weatherService = weatherService;
}

@PayloadRoot(
        localPart = "GetTemperaturesRequest",
        namespace = namespaceUri)
protected GetTemperaturesResponse getTemperature(GetTemperaturesRequest request) {
    List<TemperatureInfo> temperatures = weatherService.getTemperatures(request.getCity(), request.getDates());
    return new GetTemperaturesResponse(temperatures);
}
}

I'm deploying to Tomcat right off the root ("/") - no errors, deploys fine. Below is the resulting wsdl, but one interesting note is that I can hit it with any URL starting with http://localhost:8080 and ending with "/temperature.wsdl". i.e. http://localhost:8080/weather/services/temperature.wsdl nets me the same wsdl as http://localhost:8080/blah/blah/blah/temperature.wsdl

WSDL:

</wsdl:service>
</wsdl:definitions>

I am trying to setup a SoapUI test against these by pointing SoapUI to: http://localhost:8080/weather/services/temperature.wsdl

Which generates a correct-looking (I think) SOAP request:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:sch="http://nick.com/weather/schemas">
<soapenv:Header/>
<soapenv:Body>
   <sch:GetTemperaturesRequest>
      <sch:city>Chicago</sch:city>
      <!--1 to 5 repetitions:-->
      <sch:date>2014-06-24</sch:date>
   </sch:GetTemperaturesRequest>
</soapenv:Body>
</soapenv:Envelope>

But sending the request through gives me a 404 response:

HTTP/1.1 404 Not Found

Any insights on what I might be doing wrong? THANKS!

Solution

Wow, unbelievable - of all things, it was the access modifier on my "getTemperature()" method in TemperatureMarshallingEndpoint. It was "protected", but needed to be "public" (works like a charm after making the change!)

Nice one, I didn't think to look at that (-:
