Question

I am trying to post an soap xml with Retrofit but it\'s failing, I\'m using a Simple XML Framework to model a SOAP request that looks like this:

I have made one sample for this kind of webservices. (using webservicex as example, too). You can see it at my blog or in my github

UPDATE

Needed libraries:

...
    compile 'com.squareup.okhttp3:logging-interceptor:3.3.1'
    compile 'com.squareup.okhttp3:okhttp:3.3.1'
    compile 'com.squareup.okhttp3:okhttp-urlconnection:3.3.1'

    compile 'com.squareup.retrofit2:retrofit:2.1.0'
    compile ('com.squareup.retrofit2:converter-simplexml:2.1.0'){
        exclude group: 'stax', module: 'stax-api'
        exclude group: 'stax', module: 'stax'
        exclude group: 'xpp3', module: 'xpp3'
    }
...

The sample is for this webservice: http://www.webservicex.net/New/Home/ServiceDetail/42

First of all, you have to create Retrofit instance:

HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();

interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

Strategy strategy = new AnnotationStrategy();

Serializer serializer = new Persister(strategy);

OkHttpClient okHttpClient = new OkHttpClient.Builder()
        .addInterceptor(interceptor)
        .connectTimeout(2, TimeUnit.MINUTES)
        .writeTimeout(2, TimeUnit.MINUTES)
        .readTimeout(2, TimeUnit.MINUTES)
        .build();

Retrofit retrofit =  new Retrofit.Builder()
        .addConverterFactory(SimpleXmlConverterFactory.create(serializer))
        .baseUrl("http://www.webservicex.net/")
        .client(okHttpClient)
        .build();

After that, you have to create the API object:

    public interface UsStatesApi {

    @Headers({
            "Content-Type: text/xml",
            "Accept-Charset: utf-8"
    })
    @POST("/uszip.asmx")
    Call<UsStatesResponseEnvelope> requestStateInfo(@Body UsStatesRequestEnvelope body);

}

For creating your entities, you have to annotate them correctly. These are the request classes (response classes are made in the same way):

class: UsStatesRequestEnvelope

@Root(name = "soap12:Envelope")
@NamespaceList({
        @Namespace( prefix = "xsi", reference = "http://www.w3.org/2001/XMLSchema-instance"),
        @Namespace( prefix = "xsd", reference = "http://www.w3.org/2001/XMLSchema"),
        @Namespace( prefix = "soap12", reference = "http://www.w3.org/2003/05/soap-envelope")
})
public class UsStatesRequestEnvelope {

    @Element(name = "soap12:Body", required = false)
    private UsStatesRequestBody body;

    public UsStatesRequestBody getBody() {
        return body;
    }

    public void setBody(UsStatesRequestBody body) {
        this.body = body;
    }
}

class : UsStatesRequestBody

@Root(name = "soap12:Body", strict = false)
public class UsStatesRequestBody {

    @Element(name = "GetInfoByState",required = false)
    private UsStatesRequestData usStatesRequestData;

    public UsStatesRequestData getUsStatesRequestData() {
        return usStatesRequestData;
    }

    public void setUsStatesRequestData(UsStatesRequestData usStatesRequestData) {
        this.usStatesRequestData = usStatesRequestData;
    }
}

class: UsStatesRequestData

@Root(name = "GetInfoByState", strict = false)
@Namespace(reference = "http://www.webserviceX.NET")
public class UsStatesRequestData {

    @Element(name = "USCity", required = false)
    private String city;

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

}
