How to use a class customization to resolve file generating conflicts

Question

The error message you are facing basically states that some names in the the typessection of your wsdl are used two times. In your case all <element>tags have the same name as their corresponding types (defined as <complexType>).

Example:

  <s:element name="SearchFlights">
    <s:complexType>
      <s:sequence>
        <s:element minOccurs="0" maxOccurs="1" name="SoapMessage" type="tns:SearchFlights" />
      </s:sequence>
    </s:complexType>
  </s:element>

  <s:complexType name="SearchFlights">
    <s:complexContent mixed="false">
      <s:extension base="tns:SoapMessageBase">
        <s:sequence>
          <s:element minOccurs="0" maxOccurs="1" name="Request" type="tns:SearchFlightsRequest" />
          <s:element minOccurs="0" maxOccurs="1" name="Response" type="tns:SearchFlightsResponse" />
        </s:sequence>
      </s:extension>
    </s:complexContent>
  </s:complexType>

This is quite uncommon.

There are basically two options to resolve these issues:

Use autoNameResolution

 <plugin>
     <groupId>org.jvnet.jaxb2.maven2</groupId>
     <artifactId>maven-jaxb2-plugin</artifactId>
     <version>0.13.1</version>
     <executions>
         <execution>
             <goals>
                 <goal>generate</goal>
             </goals>
         </execution>
     </executions>
     <configuration>

         <args>
             <arg>-XautoNameResolution</arg>
         </args>

         <schemaLanguage>WSDL</schemaLanguage>
         <generatePackage>hello.wsdl</generatePackage>
         <schemas>
             <schema>
                 <url>http://www5v80.elsyarres.net/service.asmx?wsdl</url>
             </schema>
          </schemas>
      </configuration>
  </plugin>

The plugin will resolve all naming conflicts through appending numbers to every colliding name. In the above mentioned case of SearchFlights this will result in SearchFlights and SearchFlights2 being generated.

A better way would be to use a binding file to resolve all name conflicts in advance. Binding files mostly contain XPATHexpression and transformation rules.
A binding file that appends to every declarations name is the following:

<?xml version="1.0" encoding="UTF-8"?>
<jaxws:bindings wsdlLocation="http://www5v80.elsyarres.net/service.asmx?wsdl"
            xmlns:jaxws="http://java.sun.com/xml/ns/jaxws"
            xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
            xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" version="2.1"
            xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <jaxws:bindings node="wsdl:definitions/wsdl:types/xs:schema[@targetNamespace="ElsyArres.API"]">
        <jaxb:schemaBindings>
            <jaxb:nameXmlTransform>
                <jaxb:elementName suffix="Elem"/>
            </jaxb:nameXmlTransform>
        </jaxb:schemaBindings>
    </jaxws:bindings>
</jaxws:bindings>

There are other options for jaxb:nameXmlTransform like suffixes and prepending to other kind of xml elements (like types).

Sadly i could not get to work this binding file with the org.jvnet.jaxb2.maven2:maven-jaxb2-plugin( but i am sure there is a working configuration)

It nevertheless works with the org.codehaus.mojo:jaxws-maven-plugin and the following configuration.

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>jaxws-maven-plugin</artifactId>
    <version>2.4.1</version>
    <executions>
        <execution>
            <goals>
                <goal>wsimport</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <bindingFiles>
         <bindingFile>${basedir}/src/main/resources/bindings.xjb</bindingFile>
        </bindingFiles>
        <wsdlUrls>
            <wsdlUrl>http://www5v80.elsyarres.net/service.asmx?wsdl</wsdlUrl>
        </wsdlUrls>
        <vmArgs>
            <vmArg>-Djavax.xml.accessExternalSchema=all</vmArg>
        </vmArgs>
    </configuration>
</plugin>
