Soap ошибка 415

Description:

I am trying to convert a SOAP Endpoint to a REST Endpoint using WSO2. While creating and sending the request in API Manager , I am getting 415 Error: Unsupported Media Type as response.

Steps to reproduce:

I am trying to convert a SOAP Endpoint to a REST Endpoint using WSO2. While creating and sending the request in API Manager , I am getting 415 Error: Unsupported Media Type as response.
On analysis, i found that Content-Type is coming as application/soap+xml, although it should come as «text/xml» .
Now to change that, I am
going to the Resources section — In-mediation and changing the value of messageType and it saves, but when i go and re-open the in-mediation again, the value gets re-setted to what it was earlier. (application/soap+xml in my case). These changes are done using the admin user. Is there any other place where I need to change it or some other file is overriding this change?
I believe this is a bug. Please fix it.
I am using WSO2 API Manager 4.0.0

this time i will be needing some help with an error that i can’t find where is the problem.

I developed a very simple java code to consume a web service but when I run it i’m getting this nasty error: «Caused by: java.io.IOException: Server returned HTTP response code: 415 for URL: http://www.dataaccess.com/webservicesserver/numberconversion.wso/NumberToWords»

Investigating about this error it said that this has something to do with the Content-Type not been supported, so downloaded SoapUI 5.6.0 to see what the WS was waiting for and it seems correct to me.

Here is my code:

package principal;

import java.io.BufferedReader;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.StringReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;

public class PruebaWS {
    public void getNumber(int number){
        String wsURL = "http://www.dataaccess.com/webservicesserver/numberconversion.wso/NumberToWords";
        URL url = null;
        URLConnection connection = null;
        HttpURLConnection httpConn = null;
        String responseString = null;
        String outputString = null;
        ByteArrayOutputStream bout = null;
        OutputStream out = null;
        InputStreamReader isr = null;
        BufferedReader in = null;
        
        String xmlInput = 
                "<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:web="http://www.dataaccess.com/webservicesserver/">" +
                "   <soapenv:Header/>" +
                "   <soapenv:Body>" +
                "      <web:NumberToWords>" +
                "         <web:ubiNum>" + number +"</web:ubiNum>" +
                "      </web:NumberToWords>" +
                "   </soapenv:Body>" +
                "</soapenv:Envelope>";
        
        try {
            url = new URL(wsURL);
            connection = url.openConnection();
            httpConn = (HttpURLConnection) connection;
            
            byte[] buffer = new byte[xmlInput.length()];
            buffer = xmlInput.getBytes();
            
            String SOAPAction = "";
            httpConn.setRequestMethod("POST");
            httpConn.setRequestProperty("SOAPAction", SOAPAction);
            httpConn.setRequestProperty("Content-Length", String.valueOf(buffer.length));
            httpConn.setRequestProperty("Content-Type", "text/xml;charset=utf-8");
            httpConn.setRequestProperty("Accept", "*/xml");
            httpConn.setDoInput(true);
            httpConn.setDoOutput(true);
            httpConn.setUseCaches(false);
            
            out = httpConn.getOutputStream();
            out.write(buffer);
            out.close();
            
            // Lee la respuesta y escribe a un output estándard
            isr = new InputStreamReader(httpConn.getInputStream());
            in = new BufferedReader(isr);
            
            while ((responseString = in.readLine()) != null)
                outputString = outputString + responseString;
            
            System.out.println(outputString);
            System.out.println("");
            
            // Obtiene la respuesta desde la llamada al webService
            Document document = parseXmlFile(outputString);
            
            NodeList nodeList = document.getElementsByTagName("m:NumberToWordsResponse");
            String webServiceResponse = nodeList.item(0).getTextContent();
            System.out.println("La respuesta del web service es: " + webServiceResponse);
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }
    
    private Document parseXmlFile(String in){
        try {
            DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
            DocumentBuilder db = dbf.newDocumentBuilder();
            InputSource is = new InputSource(new StringReader(in));
            return db.parse(is);
        } catch (ParserConfigurationException | SAXException | IOException e) {
            throw new RuntimeException(e);
        }
    }
}

And this is the error during Runtime:

Exception in thread «main» java.lang.RuntimeException:
