Why do I get a webservice to be published in two different addresses using JBoss AS7?

Question

As an exercise to get to know something about JAX-WS and CXF I decided to implement a small service that calculates BMI. It is based on this tutorial.

I would assume that only the address I specify in the xml endpoint definition is used, but actually jboss also makes it available somewhere else.

I get the same service to be available both at

http://localhost:8080/BMI/BmiCalculatorService 

and at

http://localhost:8080/BMI/services/cxfBmi.

Can anyone help?

This is my web.xml:

<web-app>
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>WEB-INF/beans.xml</param-value>
</context-param>

<listener>
    <listener-class>
        org.springframework.web.context.ContextLoaderListener
    </listener-class>
</listener>

<servlet>
    <servlet-name>CXFServlet</servlet-name>
    <display-name>CXF Servlet</display-name>
    <servlet-class>
        org.apache.cxf.transport.servlet.CXFServlet
    </servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>CXFServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>
</servlet-mapping>
</web-app>

And this is my beans.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jaxws="http://cxf.apache.org/jaxws"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">

<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />    

<jaxws:endpoint id="calcBMI"
                implementor="com.company.bmi.services.BMICalculatorImpl"
                address="/cxfBmi"/>

</beans>

The interface definition:

package com.company.bmi.services;

import javax.jws.WebParam;
import javax.jws.WebService;

@WebService
public interface BMICalculator {

public double computeBMI(@WebParam(name="weight") double weight, @WebParam(name="height") double height) ;

}

And the implementation of the service:

package com.company.bmi.services;

import javax.jws.WebService;


@WebService(endpointInterface="com.company.bmi.services.BMICalculator", serviceName="BmiCalculatorService") 
public class BMICalculatorImpl implements BMICalculator {

    @Override
    public double computeBMI(double weight, double height) {
        return weight / (height * height);
    }

}

In Jboss's log I see that indeed the first URL I mentioned is the one set as the published address for the service. Then it gets changed into the one I specified in the xml file. The thing is the first address still works, this is not correct in my opinion.

But later on in the log the server also complains about not finding the service's observer, so I wonder if this is what causes the undesirable result?

Here is the log sample:

Answer 1

The address http://localhost:8080/BMI/services/* is created by explicit CXFServlet.

While http://localhost:8080/BMI/BmiCalculatorService is created by org.jboss.wsf.stack.cxf.metadata.MetadataBuilder via implicit annotations scan.

See How to disable scanning @WebService annotations in JBoss AS 7? for cure.
