Web service using CXF, Jetty and Spring

Question

I try to create simple web service with CXF, Jetty and Spring. I create service interface

@WebService
public interface AnonymousService {

    @WebMethod
    public String getVersion();
}

and its implementation

@Service("anonymousService")
@WebService(
    serviceName = "AnonymousService",
    targetNamespace = "http://ws.test/",
    endpointInterface = "test.ws.AnonymousService"
)
public class AnonymousServiceImpl {
    public String getVersion() {
        return "Version";
    }
}

Next step I add to Spring context configuration file endpoint declaration

<jaxws:endpoint id="anonymousServiceEndpoint"
    implementor="#anonymousService" address="/anonymous" />

and configure Jetty bean

<bean id="server" class="org.mortbay.jetty.Server" destroy-method="stop">
    <property name="connectors">
    <list>
            <bean id="connector" class="org.mortbay.jetty.nio.SelectChannelConnector">
                <property name="port" value="${server.port}" />
            </bean>
        </list>
    </property>

    <property name="handlers">
        <list>
            <ref bean="workflowContext" />
        </list>
    </property>
 </bean>

<bean name="workflowContext" class="org.mortbay.jetty.servlet.Context">
    <property name="contextPath" value="/" />

        <property name="servletHandler">
            <bean class="org.mortbay.jetty.servlet.ServletHandler">
                <property name="servlets">
                    <list>
                        <bean class="org.mortbay.jetty.servlet.ServletHolder">
                            <property name="name" value="services" />
                            <property name="servlet">
                                <bean class="org.apache.cxf.transport.servlet.CXFServlet" />
                                <!--<bean class="org.apache.cxf.transport.servlet.CXFNonSpringServlet" />-->
                            </property>
                        </bean>
                    </list>
                </property>

                <property name="servletMappings">
                    <list>
                        <bean class="org.mortbay.jetty.servlet.ServletMapping">
                            <property name="servletName" value="services" />
                            <property name="pathSpec" value="/services/*" />
                        </bean>
                    </list>
                </property>
            </bean>
        </property>
</bean>

Unfortunately, when I start my application I get following stack trace

What I do wrong?

Solution 1

My problem solved by adding cxf.xml configuration file into root of classpath

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.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"/>

</beans>

I didn't do this before, because I didn't understand what should be in META_INF/cxf/.xml files. In fact, these files do not need to be created - they are already exists in cxf-rt- packages!

Solution 2

Did you see the last exception in the chain:

Caused by: java.net.MalformedURLException: no protocol: /anonymous

The "/anonymous" string is in the jaxws:endpoint tag, so it probably uses another syntax there.

I wrote jaxws:endpoint tag in accordance with these instructions: cxf.apache.org/docs/writing-a-service-with-spring.html , cxf.apache.org/docs/jax-ws-configuration.html .

[Yogesh Chawla]

In newer version of CXF, you only need cxf.xml and not the other imports: <import resource="classpath:META-INF/cxf/cxf.xml" />
