CXF, wsdl2java. Custom port name

Question

Short question: Can I somehow bind wsdl:port name to generate custom java field name in service?

Long question: I have a wsdl with such part:

<wsdl:service name="123xxx">
   <wsdl:port name="123xxxHttpSoap11Endpoint" binding="tns:123xxxSoap11Binding">
     <soap:address location="..."/>
   </wsdl:port>
</wsdl:service>

And a maven wsdl2java goal which generates the service with name 123xxx (which I've already fixed with binding by calling it MyService) and inside this service it generates a field:

public class MyService extends Service {
    ...
    public final static QName 123xxxHttpSoap11Endpoint = 
                 new QName("http://new.webservice.namespace", "123xxxHttpSoap11Endpoint");
    ...
}

This causing a compile errors because variables can't start with numbers in Java. And I can't find a way to somehow customize this generated code without changing the original wsdl.

So, is there a way to bind it through the cxf bindings, like it is done with service itself:

<bindings...>
    <bindings node="wsdl:definitions/wsdl:service">
    <class name="MyService"/>
    </bindings>
</bindings>

or may be there are some other ways to achive this?

Answer 1

Finally I found the solution. Of course it's an overhead for common wsdl-generating process, but it is only (or almost only) the way to satisfy my restrictions.

First I've checked the sources of the cxf library and found that there is a method for generating Port element:

org.apache.cxf.tools.wsdlto.frontend.jaxws.processor.internal.ServiceProcessor#processPort

which just creates JavaPort with name, fetched from the original wsdl and does not process it with any binding:

JavaPort jport = new JavaPort(NameUtil.mangleNameToClassName(port.getName().getLocalPart()));

Going further I found that there is a possibility to inject custom code generator, which is responsible for creation of java classes from cxf model.

After some research I found this answer which helped me to make it.

So I've created a separate module with such class (check comments):

//note that I've put my class inside the package, 
//which is used for other default generators in cxf
package org.apache.cxf.tools.wsdlto.frontend.jaxws.generators;

import java.util.List;
import java.util.Map;

import org.apache.cxf.tools.common.ToolContext;
import org.apache.cxf.tools.common.ToolException;
import org.apache.cxf.tools.common.model.JavaPort;
import org.apache.cxf.tools.common.model.JavaServiceClass;

public class CustomSEIGenerator extends SEIGenerator {

    @Override
    public void generate(ToolContext penv) throws ToolException {
        //no streams, because we still on java 7
        //fetch all services
        Map<String, JavaServiceClass> ss = penv.getJavaModel().getServiceClasses();
        for (Map.Entry<String, JavaServiceClass> s : ss.entrySet()) {
            //fetch all ports from each service
            for (JavaPort port : s.getValue().getPorts()) {
                //set custom name to each port
                port.setName("_" + port.getName);
            }
        }
    }
}

and placed a tools-plugin.xml into META-INF folder:

<?xml version="1.0" encoding="utf-8"?>
<plugin xmlns="http://cxf.apache.org/tools/plugin" name="play" version="" provider="play.typesafe.com">
    <frontend name="sample" package="org.apache.cxf.tools.wsdlto.frontend.jaxws" profile="JAXWSProfile">
        <container name="JAXWSContainer" package="org.apache.cxf.tools.wsdlto.frontend.jaxws" toolspec="jaxws-toolspec.xml"/>
        <processor name="WSDLToJavaProcessor" package="org.apache.cxf.tools.wsdlto.frontend.jaxws.processor"/>
        <builder name="JAXWSDefinitionBuilder" package="org.apache.cxf.tools.wsdlto.frontend.jaxws.wsdl11"/>
        <generators package="org.apache.cxf.tools.wsdlto.frontend.jaxws.generators">
            <generator name="CustomSEIGenerator"/>
            <generator name="AntGenerator"/>
            <generator name="ClientGenerator"/>
            <generator name="FaultGenerator"/>
            <generator name="ImplGenerator"/>
            <generator name="SEIGenerator"/>
            <generator name="ServerGenerator"/>
            <generator name="ServiceGenerator"/>
        </generators>
    </frontend>
</plugin>

(note that I've put my custom generator before default ones to make them work with modified model).

Next I've just modified my pom file according to the answer, which I've posted above, and was happy to see it's working.
