IllegalAnnotationExceptions: Two classes have the same XML type name. Code generated by CXF plugin

Question

I have two WSDLs from which I generate Java code using maven cxf-codegen-plugin (org.apache.cxf). Both of them use the same namespace and contains complex types of the same name which was reason why I experienced issues with conflicting java class names. I decided to solve it using bindings.xml:

<jaxws:bindings
        xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
        xmlns:jaxws="http://java.sun.com/xml/ns/jaxws"
        xmlns="http://www.w3.org/2001/XMLSchema"
        version="2.1">
    <jaxws:bindings wsdlLocation="./TaskService_v1.wsdl" node="xsd:schema">
        <jaxb:schemaBindings>
            <jaxb:nameXmlTransform>
                <jaxb:typeName prefix="TaskService" />
                <jaxb:elementName prefix="TaskService" />
            </jaxb:nameXmlTransform>
        </jaxb:schemaBindings>
    </jaxws:bindings>
</jaxws:bindings>

This renamed for example generated class B2BParameter to TaskServiceB2BParameter so I stopped getting conflicting names issues but I ran into another issue:

Unknown JAXB exception; nested exception is com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 4 counts of IllegalAnnotationExceptions
Two classes have the same XML type name "{http://serviceinterface.b2b.adx.com}B2BParameter". Use @XmlType.name and @XmlType.namespace to assign different names to them.
this problem is related to the following location:
    at com.adx.b2b.serviceinterface.TaskServiceB2BParameter
this problem is related to the following location:
    at com.adx.b2b.serviceinterface.B2BParameter
    at protected java.util.List com.adx.b2b.serviceinterface.B2BRequest.parameter
    at com.adx.b2b.serviceinterface.B2BRequest
...

This is generated TaskServiceB2BParameter.java:

package com.axd.b2b.serviceinterface_v1;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "B2BParameter", propOrder = {
    "name",
    "value"
})
public class TaskServiceB2BParameter {
    ...
}

How can update my bindings.xml to change @XmlType.name appropriately? Or do I really need to change target package? Thank you in advance!

The problem was that single marshaller found classes with the same element name. I resolved this problem this way:

1) Generate classes into different packages

        <plugin>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-codegen-plugin</artifactId>
            <version>3.3.3</version>
            <executions>
                <execution>
                    <id>generate-sources</id>
                    <phase>generate-sources</phase>
                    <configuration>
                        <sourceRoot>${project.build.directory}/generated-sources/cxf</sourceRoot>
                        <wsdlOptions>
                            <wsdlOption>
                                <wsdl>${basedir}/src/main/resources/META-INF/wsdl/Service1.xml</wsdl>
                                <packagenames>
                                    <packagename>com.xxx.service1</packagename>
                                </packagenames>
                            </wsdlOption>
                            <wsdlOption>
                                <wsdl>${basedir}/src/main/resources/META-INF/wsdl/Service2.xml</wsdl>
                                <packagenames>
                                    <packagename>com.xxx.service2</packagename>
                                </packagenames>
                            </wsdlOption>
                        </wsdlOptions>
                    </configuration>
                    <goals>
                        <goal>wsdl2java</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

2) Create special marshaller bean for each service

@Configuration
public class WebServiceConfig {

@Bean
public Jaxb2Marshaller service1Marshaller() {
    Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
    marshaller.setPackagesToScan("com.xxx.service1");
    return marshaller;
}

@Bean
public Jaxb2Marshaller service2Marshaller() {
    Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
    marshaller.setPackagesToScan("com.xxx.service2");
    return marshaller;
}
}
