WSDL SOAP Web服务Java客户端的错误415

这一次我需要一些帮助来解决一个我找不到问题所在的错误

我开发了一个非常简单的java代码来使用web服务,但当我运行它时,我得到了一个严重的错误:“由:java.io.IOException引起:服务器返回HTTP响应代码:415 for URL:http://www.dataaccess.com/webservicesserver/numberconversion.wso/NumberToWords"

调查此错误时,它说这与不支持的内容类型有关,因此下载了SoapUI 5.6.0以查看WS在等待什么,我认为这是正确的

这是我的密码:

            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);
        }
    }
}

这是运行时的错误:

Exception in thread "main" java.lang.RuntimeException: java.io.IOException: Server returned HTTP response code: 415 for URL: http://www.dataaccess.com/webservicesserver/numberconversion.wso/NumberToWords at principal.PruebaWS.getNumber(PruebaWS.java:83) at principal.Main.main(Main.java:6) Caused by: java.io.IOException: Server returned HTTP response code: 415 for URL: http://www.dataaccess.com/webservicesserver/numberconversion.wso/NumberToWords at java.base/sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1919) at java.base/sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1515) at principal.PruebaWS.getNumber(PruebaWS.java:67) ... 1 more C:\Local\NetBeans\Cache\11.1\executor-snippets\run.xml:111: The following error occurred while executing this line: C:\Local\NetBeans\Cache\11.1\executor-snippets\run.xml:68: Java returned: 1 BUILD FAILED (total time: 2 seconds)

任何帮助都是有价值的

    好的,在调查了一段时间后,我发现这个错误与Web服务it本身有关,我将它与另一个进行了交换,它没有任何问题。经验教训:并非所有的Web服务都能正常工作
