CXF - method arguments are null

Question

I use CXF 3.3.6 with Jetty 9.4.14. Jetty doesn't know about CXF and to link them I use web.xml. In that descriptor I set CXF servlet in which I override loadBus method. When I go to http://127.0.0.1:8080/webservices/calcService?wsdl I see wsdl of the service. These are dependencies I use:

cxf-rt-transports-http-3.3.6.jar
cxf-rt-frontend-jaxws-3.3.6.jar
cxf-core-3.3.6.jar
cxf-rt-frontend-simple-3.3.6.jar
cxf-rt-bindings-soap-3.3.6.jar
cxf-rt-wsdl-3.3.6.jar
cxf-rt-databinding-jaxb-3.3.6.jar
jakarta.xml.ws-api-2.3.2.jar
jakarta.xml.soap-api-1.4.1.jar
jakarta.jws-api-1.1.1.jar
xmlschema-core-2.2.5.jar
istack-commons-runtime-3.0.8.jar
woodstox-core-5.0.3.jar
stax2-api-3.1.4.jar
wsdl4j-1.6.3.jar

//having lost any hope I also added the following:
cxf-rt-bindings-xml-3.3.6.jar
cxf-rt-ws-addr-3.3.6.jar
cxf-rt-ws-policy-3.3.6.jar
cxf-rt-transports-http-jetty-3.3.6.jar
neethi-3.1.1.jar
xml-resolver-1.2.jar
txw2-2.3.2.jar
stax-ex-1.8.3.jar
saaj-impl-1.4.0-b03.jar
mimepull-1.9.7.jar
FastInfoset-1.2.16.jar
jaxb-runtime-2.3.2.jar
jboss-rmi-api_1.0_spec-1.0.6.Final.jar
jacorb-omgapi-3.9.jar

This is my class

@WebService(name="CalculatorService", serviceName="CalculatorService")
public class CalculatorService {

    @WebMethod
    public double addNumbers(double v1, double v2) {
        return v1 + v2;
    }
}

This is generated wsdl

Upon generated wsdl I generate (using plugin) java client stubs. The problem is that when via client I try to call my service my arguments for method are ignored. This is what I see using ngrep:

#######

As you see both arguments for addNumbers are passed but they are ignored.

And this is the stack

Could anyone help to solve this problem?

I did a test project that can be run by mvn install here.

Looks you have incorrect namespace based on wsdl

Update

Server method

@WebService(name="CalculatorService", 
        serviceName="CalculatorService")
public class CalculatorService {

    @WebMethod
    public double addNumbers(@WebParam(name="value1") double v1, @WebParam(name="value2") double v2) {
        return v1 + v2;
    }
}

In your case cxf-java2ws-plugin was generating a WSDL document ( the same one you are referring in your integration test ) was the one with JAX WS annotation. Note below the WSDL generated by plugin and the actual wsdl used by service. Pay attention to the element form defaults and local elements.

Plugin Generated WSDL

Service Actual WSDL ( with ServerFactoryBean doesn't take JAX WS annotation into account)

So your request was failing from integration test as server doesn't understand the request being sent.

Fix was to use JaxWsServerFactoryBean when initializing servlet. Now the service wsdl matches what was generated by plugin.

CXF - method arguments are null
