How to use a class customization to resolve file generating conflicts

If the autoNameResolution fix

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

doesn't work, try:

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

The error message you are facing basically states that some names in the the typessection of your wsdl are you 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>
