SOAP Message as a String Sent to End Point in Java

I have a String which is a SOAP message.
String message = "<?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header>
<xyz:Config xmlns:hal="http://example.com/xyz" applicationId="Client" conversationId="000" host="ENDPOINT">
</xyz:Config>
</SOAP-ENV:Header>
<SOAP-ENV:Body>
<PaymentRQ xmlns="http://www.iata.org/IATA/4/0"
xmlns:common="http://www.iata.org/IATA/common/4/0">
<PaymentDetails>
<PaymentDetail>
<common:PaymentCard CardNumber="1233444444444" CardType="100" ExpireDate="1120" SeriesCode="123">
</PaymentDetail>
</PaymentDetails>
</PaymentRQ>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
";
I need to send this as a SOAP request to a local server running on 8080
So, url would be http://localhost:8080/XYZService/xyz
Then fetch the SOAP response and read its values.
Kindly assist on how I can send the String as a SOAP message to the aforementioned url. Thanks in advance.

You can pass null to SOAPAction if you don't have one.
for serverAddress pass serverIp + ServerPort(ex: 172...*:8088).
public String sendSoapRequest(String serverAdress, String message , String SOAPAction)
{
OutputStream httpOutputStream = null;
byte[] byteArrayStream = message .getBytes();
URL url = null;
try {
url = new URL("http://"+serverAdress);
} catch (MalformedURLException e) {
e.printStackTrace();
}
HttpURLConnection httpURLConnection = null;
try {
httpURLConnection = (HttpURLConnection)url.openConnection();
} catch (IOException e) {
e.printStackTrace();
}
// Set the appropriate HTTP parameters.
httpURLConnection.setRequestProperty("Content-Length",
String.valueOf(byteArrayStream.length));
httpURLConnection.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
httpURLConnection.setRequestProperty("SOAPAction", SOAPAction);
try {
httpURLConnection.setRequestMethod("POST");
} catch (ProtocolException e) {
e.printStackTrace();
}
httpURLConnection.setDoOutput(true);
httpURLConnection.setDoInput(true);
try {
httpOutputStream = httpURLConnection.getOutputStream();
} catch (IOException e) {
e.printStackTrace();
}
//Write the content of the request to the outputstream of the HTTP Connection.
try {
httpOutputStream.write(byteArrayStream);
httpOutputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
BufferedReader httpInputBuufferedReader = null;
try {
httpInputBuufferedReader = new BufferedReader(new InputStreamReader(httpURLConnection.getInputStream()));
} catch (IOException e) {
e.printStackTrace();
Log.e(LOG_TAG,"IOException reading HTTP Input message ");
return null;
}
//Write the SOAP message response to a String.
StringBuilder returnOutputString = new StringBuilder();
try {
String line = "";
while ((line = httpInputBuufferedReader.readLine()) != null) {
returnOutputString.append(line);
}
} catch (IOException e) {
e.printStackTrace();
Log.e(LOG_TAG, "IOEception while reading HTTP input buffered reading");
}
return returnOutputString.toString();
}

Why isn't my node.js restful api recieving this output stream from Java Android?

I have a class audio sender which makes a connection to the nodejs server and uploads an audio file in POST method mode.
public class AudioSender implements Callable<JSONObject> {
String outputFile;
AudioSender(String fileLocation){
outputFile=fileLocation;
}
public JSONObject call(){
URL url = null;
HttpURLConnection urlConnection = null;
InputStream audioInputStream=null;
JSONObject response=null;
byte buffer[]=new byte[16];
try {
url = new URL("http://192.168.0.106:3000/upload");
} catch (MalformedURLException e) {
e.printStackTrace();
} finally {
try {
urlConnection = (HttpURLConnection) url.openConnection();
} catch (IOException e) {
e.printStackTrace();
} finally {
urlConnection.setDoOutput(true);
urlConnection.setChunkedStreamingMode(16);
urlConnection.setRequestProperty("Content-Type","multipart/form-data");
urlConnection.setRequestProperty("Connection", "Keep-Alive");
urlConnection.setRequestProperty("Cache-Control", "no-cache");
urlConnection.setRequestProperty(
"Content-Type", "multipart/form-data;boundary=*****");
try {
OutputStream out = new BufferedOutputStream(urlConnection.getOutputStream());
try {
audioInputStream = new BufferedInputStream(new FileInputStream(outputFile));
Log.d("hello","audioinputstream");
} catch (FileNotFoundException e) {
e.printStackTrace();
} finally {
while(audioInputStream.read(buffer)!=-1) {
out.write(buffer);
Log.d("buffer",buffer.toString());
}
try {
audioInputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
InputStream in = new BufferedInputStream(urlConnection.getInputStream());
StringBuilder total = new StringBuilder();
while(in.read(buffer)!=-1)
total.append(buffer);
Log.d("response",total.toString());
try {
response = new JSONObject(total.toString());
}catch(JSONException e){
Log.e("Response Parse Error", "Could not parse malformed JSON");
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
return response;
}
This is the upload that executes the AudioSender callable.
public void upload() {
JSONObject response=null;
AudioSender sender=new AudioSender(outputFile);
FutureTask<JSONObject> uploadTask=new FutureTask<JSONObject>(sender);
ExecutorService executorService= Executors.newFixedThreadPool(1);
executorService.execute(uploadTask);
Log.d("s","was here");
while(true){
if(uploadTask.isDone()){
try{
response=uploadTask.get();
}catch(InterruptedException|ExecutionException e){
e.printStackTrace();
Log.e("ee","ee",e.getCause());
}
}
}
}
I pretty much know this isn't node js's fault but here's the server code:
app.post('/upload',function(req,res){
console.log("someone called!");
req.on('data',function(chunk){
console.log('res');
console.log(chunk);
});
req.on('end',function(){
console.log("done!");
res.send({'name':'sg'});
});});
When I call upload(), the server console prints
someone called!
done!
I was debugging and found that indeed I am receiving the responded json object from the server. And I don't know if out.write(buffer) is doing the job, but debugging it shows that the buffer value is changing and is in par with my audio file's size.
Please do not suggest using ION or anything else.

I solved the problems by setting up the URLConnection as follows:
boundary = "===" + System.currentTimeMillis() + "===";
urlConnection.setUseCaches(false);
urlConnection.setDoOutput(true); // indicates POST method
urlConnection.setDoInput(true);
urlConnection.setRequestProperty("Content-Type","multipart/form-data; boundary=" + boundary);

How to get the response data from cloud to string

I want to get the response to a string variable from the data from the cloud.
ClientResource cr = new ClientResource("http://localhost:8888/users");
cr.setRequestEntityBuffering(true);
try {
try {
cr.get(MediaType.APPLICATION_JSON).write(System.out);
} catch (IOException e) {
e.printStackTrace();
}
} catch (ResourceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
I have response as JSON in the console and I want to convert it to string , Is the GSON library would be helpful? I haven't used it yet .What modifications should I need to do in my codes? Can anybody help me here.

In fact, Restlet receives the response payload as String and you can directly have access to this, as described below:
ClientResource cr = new ClientResource("http://localhost:8888/users");
cr.setRequestEntityBuffering(true);
Representation representation = cr.get(MediaType.APPLICATION_JSON);
String jsonContentAsString = representation.getText();
Hope it helps you,
Thierry

Below is a working example:
try {
URL url = new URL("http://localhost:8888/users");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
conn.setRequestProperty("Accept", "application/json");
if (conn.getResponseCode() != 200) {
throw new RuntimeException("Failed : HTTP error code : "
+ conn.getResponseCode());
}
BufferedReader br = new BufferedReader(new InputStreamReader(
(conn.getInputStream())));
String output;
System.out.println("Raw Output from Server .... \n");
while ((output = br.readLine()) != null) {
System.out.println(output);
}
conn.disconnect();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}

How to read string from php to android studio (java)

I don't know why i get a null value when i call the GetPHPData() function. The "out" variable returns nothing (""). I make a Toast.makeTest and it returns empty string. Please help. This is my code:
public class PHPConnect extends Activity
{
String url = "http://122.2.8.226/MITBookstore/sqlconnect.php";
HttpURLConnection urlConnection = null;
String out = null;
public String GetPHPData()
{
try {
urlConnection = (HttpURLConnection) new URL(url).openConnection();
urlConnection.setConnectTimeout(5000);
urlConnection.setReadTimeout(10000);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try
{
BufferedReader in = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
out = readStream(in);
}
catch (Exception e)
{
Toast.makeText(getApplicationContext(),e.getMessage(),Toast.LENGTH_SHORT).show();
}
finally
{
urlConnection.disconnect();
return out;
}
}
private String readStream(BufferedReader is)
{
try
{
ByteArrayOutputStream bo = new ByteArrayOutputStream();
int i = is.read();
while(i != -1)
{
bo.write(i);
i = is.read();
}
return bo.toString();
} catch (IOException e)
{
return e.getMessage();
}
}
}
By the way, im running a wamp server and I port forwarded my router, on local host, the url works, but on remote connection, it won't return a string. You can try out the url, the result is: "This is the output:emil"

Can you please try below piece of code which is working for me, also add INTERNET permission in android manifest file. Still if it is not working then may be issue with server end then try to debug it.
URL url;
try {
url = new URL("myurl");
HttpURLConnection urlConnection = (HttpURLConnection) url
.openConnection();
InputStream in = urlConnection.getInputStream();
InputStreamReader isw = new InputStreamReader(in);
int data = isw.read();
while (data != -1) {
char current = (char) data;
data = isw.read();
System.out.print(current);
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

FileNotFoundException on HttpsURLConnection with POST and unmutable doOutput variable

I'm trying to POST some data to an https url, in my android application, in order to get a json format response.
I'm facing two problems:
is = conn.getInputStream();
throws
java.io.FileNotFoundException
I don't get if i do something wrong with HttpsURLConnection.
The second problem arose when i debug the code (used eclipse); I set a breakpoint after
conn.setDoOutput(true);
and, when inspecting conn values, I see that the variable doOutput remain set to false and type GET.
My method for https POST is the following, where POSTData is a class extending ArrayList<NameValuePair>
private static String httpsPOST(String urlString, POSTData postData, List<HttpCookie> cookies) {
String result = null;
HttpsURLConnection conn = null;
OutputStream os = null;
InputStream is = null;
try {
URL url = new URL(urlString);
conn = (HttpsURLConnection) url.openConnection();
conn.setReadTimeout(10000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("POST");
conn.setUseCaches (false);
conn.setDoInput(true);
conn.setDoOutput(true);
if(cookies != null)
conn.setRequestProperty("Cookie",
TextUtils.join(";", cookies));
os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
writer.write(postData.getPostData());
writer.flush();
writer.close();
is = conn.getInputStream();
BufferedReader r = new BufferedReader(
new InputStreamReader(is));
StringBuilder total = new StringBuilder();
String line;
while ((line = r.readLine()) != null) {
total.append(line);
}
result = total.toString();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (ProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
if (os != null) {
try {
os.close();
} catch (IOException e) {
}
}
if (is != null) {
try {
is.close();
} catch (IOException e) {
}
}
if (conn != null) {
conn.disconnect();
}
}
return result;
}
A little update: apparently eclipse debug lied to me, running and debugging on netbeans shows a POST connection. Error seems to be related to parameters i'm passing to the url.

FileNotFoundException means that the URL you posted to doesn't exist, or couldn't be mapped to a servlet. It is the result of an HTTP 404 status code.
Don't worry about what you see in the debugger if it doesn't agree with how the program behaves. If doOutput really wasn't enabled, you would get an exception obtaining the output stream.
