JAVA木卫一。IOException:服务器返回了URL:“SoapEndPoint URL”的HTTP响应代码：500

Question

我的肥皂API在localHost上运行。当我从浏览器或肥皂用户界面访问它时，它工作正常。但是当我从我的java客户端访问它时，它会抛出500个错误

我试图调试代码，但找不到任何东西。服务器日志也不会打印任何内容。只有tomcat访问日志显示请求的响应代码

public class PostSoapRequest {
    String soapEndpointUrl = "http://10.142.240.103:8082/notification-adaptor/services/ChangeTrigger";

    public void postRequest(ChangeDeviceTrigger_Element changeDeviceTrigger) {
        try {
            URL obj = new URL(soapEndpointUrl);
            HttpURLConnection con = (HttpURLConnection) obj.openConnection();
            con.setRequestMethod("POST");
            con.setRequestProperty("Content-Type", "text/xml;charset=UTF-8");
            con.setRequestProperty("SOAPAction", "http://dpa.nokia.com/ChangeDeviceTrigger/");
            con.setRequestProperty("Connection", "Keep-Alive");
            con.setRequestProperty("User-Agent","Apache-HttpClient/4.1.1");
            String xml = RequestXml.getXmlRequest();
            con.setDoOutput(true);
            DataOutputStream wr = new DataOutputStream(con.getOutputStream());
            wr.writeBytes(xml);
            wr.flush();
            wr.close();
            String responseStatus = con.getResponseMessage();
            System.out.println("responseStatus :" + responseStatus);
            System.out.println("getResponseCode :" + con.getResponseCode());
            BufferedReader reader = null;

            if (con.getResponseCode() == 200) {
                reader = new BufferedReader(new InputStreamReader(con.getInputStream()));
                String inputLine;
                StringBuffer response = new StringBuffer();
                while ((inputLine = reader.readLine()) != null) {
                    response.append(inputLine);
            }
                reader.close();
                System.out.println("response:" + response.toString());
            }else {
                reader = new BufferedReader(new InputStreamReader(con.getErrorStream()));
            }
            System.out.println(reader.read());

            BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
            String inputLine;
            StringBuffer response = new StringBuffer();
            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
            }
            in.close();

        } catch (Exception e) {
            e.printStackTrace();
        }

我发现发布到服务endpoint的肥皂请求xml是错误的。请求中有一个额外的“\”字符。问题还没解决
