Using different package names for bindings and wsdl using the jaxws maven plugin

Question

We have a special requirement with our application: files generated against the wsdl should have a given package name and files generated against xsd files should have another package name.

There does not seem to have a way to customize this with the jaxws maven plugin. Here is our current configuration:

    <execution>
        <id>wsimport-finderpro</id>
        <phase>generate-sources</phase>
        <goals>
            <goal>wsimport</goal>
        </goals>
        <configuration>
            <bindingDirectory>src/main/resources/xml-resources/web-service-references/B2T_DataModel.asmx/xsd</bindingDirectory>
            <bindingFiles>
                <bindingFile>ServerResponse_login.xsd</bindingFile>
                <bindingFile>OpenDirectAccessSession.xsd</bindingFile>
            </bindingFiles>
            <!--wsdls file directory -->
            <wsdlDirectory>src/main/resources/xml-resources/web-service-references/B2T_DataModel.asmx/wsdl</wsdlDirectory>
            <!-- which wsdl file -->
            <wsdlFiles>
                <wsdlFile>B2T_DataModel.asmx.wsdl</wsdlFile>
            </wsdlFiles>
            <!-- Keep generated files -->
            <keep>true</keep>
            <!-- Package name -->
            <packageName>com.mycompany.world.worldlink.finderpro.ws</packageName>
            <!-- generated source files destination-->
            <sourceDestDir>target/generated-code/src</sourceDestDir>
            <staleFile>target/jaxws/fp/.staleFlag</staleFile>
            <target>2.1</target>
        </configuration>
    </execution>

Can anyone please advise?

edit 1: I came up with the following code:

            <execution>
                <id>wsimport-finderpro-01</id>

                    <!-- Keep generated files -->
                    <keep>true</keep>
                    <!-- Package name -->
                    <packageName>com.ids.world.worldlink.finderpro.xmlstubs.allMyEntityQuotes</packageName>

                </configuration>
            </execution>

The issue is that I noticed that many classes are regenerated several times (here x2) and I end up with same classes in different packages.

How can I ensure that classes generated for the wsdl are generated once and classes for the xsd are generated and placed in their respective package?
