https://account-d.docusign.com/restapi/v2.1/accounts/xxx/envelopes is not a valid DocuSign endpoint.
The Account Server (account-d.docusign.com) is used to get a token and make a UserInfo call to determine the correct base URL for a particular account.
Because you're in the Demo environment, your base url will begin with https://demo.docusign.net
Well, one issue is that the the Document model in Java is Document from
import com.docusign.esign.model.Document;
To debug, I suggest using the DocuSign API logging feature. Then update (edit) your question to include the JSON shown in the log.
Were you able to run the code examples for Java? See eg-03-java-auth-code-grant
Also, please tell us (by editing your question) what you are trying to do.

I am using Grails Plugin rest=0.7 for consuming a Rest Webservice.
Everything works fine when the response from the service is xml but in case if response is file type like pdf it must start downloading on sending the request but the downloading is not starting at all.
The below code in implemented in a grails service.
String httpUrl = 'http://abc.com/myService'
String data = '<methodcall protocol="2" method="avalidmethodname"><cmdid/><data><project_id>1</project_id><user_id>2</user_id><operation>ABC</operation><filter><status_type_id>1</status_type_id><scope_bits>00</scope_bits></filter></data></methodcall>'
String respText = ''
HttpClient httpClient = new DefaultHttpClient()
HttpResponse response
try {
HttpPost httpPost = new HttpPost(httpUrl)
httpPost.setHeader("Content-Type", "text/xml")
HttpEntity reqEntity = new StringEntity(data, "UTF-8")
reqEntity.setContentType("text/xml")
reqEntity.setChunked(true)
httpPost.setEntity(reqEntity)
response = httpClient.execute(httpPost)
// HttpEntity resEntity = response.getEntity()
// respText = resEntity.getContent().text
}
finally {
httpClient.getConnectionManager().shutdown()
}
return response
// return respText
The commented lines in code is for the case of xml response.
Please help me to resolve this problem, i am not sure the approach i am using is valid in case of file response from the webservice.
Try adding
response.setContentType("text/pdf");
before
response = httpClient.execute(httpPost);
What I want to do is submit a web form from a java application. The form I need to fill out is located here: http://cando-dna-origami.org/
When the form is submitted, the server sends a confirmation email to the email address given, which for now I'm just checking by hand. I've tried filling out the form manually, and the emails get sent fine. (It should also be noted that when the form is filled out incorrectly, the page just refreshes and doesn't give any feedback).
I've never done anything with http before, but I looked around for a while, and came up with the following code, which is supposed to send a POST request to the server:
String data = "name=M+V&affiliation=Company&email="
+ URLEncoder.encode("m.v#gmail.com", "UTF-8")
+ "&axialRise=0.34&helixDiameter=2.25&axialStiffness=1100&bendingStiffness=230" +
"&torsionalStiffness=460&nickStiffness=0.01&resolution=course&jsonUpload="
+ URLEncoder.encode("C:/Users/Marjie/Downloads/twisted_DNA_bundles/monotwist.L1.v1.json",
"UTF-8") + "&type=square";
URL page = new URL("http://cando-dna-origami.org/");
HttpURLConnection con = (HttpURLConnection) page.openConnection();
con.setDoOutput(true);
con.setRequestMethod("POST");
con.connect();
OutputStreamWriter out = new OutputStreamWriter(con.getOutputStream());
out.write(data);
out.flush();
System.out.println(con.getResponseCode());
System.out.println(con.getResponseMessage());
out.close();
con.disconnect();
However, when it runs it doesn't appear to do anything - that is, I don't get any emails, although the program does print "200 OK" to System.out, which seems to indicate that something got received from the server, although I'm not sure what it means exactly. I think the problem might be in the file uploading, since I wasn't sure whether that data type required a different format.
Is this a correct way to send a POST request using Java? Do I need to do something different for the file uploading? Thanks!
After reading Adam's post, I used Apache HttpClient and wrote the following code:
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("type", "square"));
//... add more parameters
UrlEncodedFormEntity entity = new UrlEncodedFormEntity(params, HTTP.UTF_8);
HttpPost post = new HttpPost("http://cando-dna-origami.org/");
post.setEntity(entity);
HttpResponse response = new DefaultHttpClient().execute(post);
post = new HttpPost("http://cando-dna-origami.org/");
post.setEntity(new FileEntity(new File("C:/Users/Marjie/Downloads/twisted_DNA_bundles/monotwist.L1.v1.json"), "text/plain; charset=\"UTF-8\""));
HttpResponse responseTwo = new DefaultHttpClient().execute(post);
However, it still doesn't seem to be working; again, I wasn't sure how the uploaded file fit into the form, so I tried just sending two separate POST requests, one with the form and one with the other data. I am still looking for a way to combine these into one request; does anybody know something about this?
You would probably be better off using something like Apache HttpClient, with which you can build up a POST request programatically.
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://.../whatever");
List <NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("param1", "value1"));
params.add(new BasicNameValuePair("param2", "value2"));
...
httpost.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
HttpResponse response = httpclient.execute(httppost);
If you need to upload a file along with your form, you will need to use a MultipartEntity instead:
MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("someParam", "someValue");
reqEntity.addPart("someFile", new FileBody("/some/file"));
....
httpost.setEntity(reqEntity);
There are some sample programs over on their site. The "Form based logon" and "Multipart encoded request entity" are good examples to start from.
It may also be worthwhile testing out your connections and taking a look at the underlying network data to see what is happening. Something like Firebug will let you see exactly what is happening in your browser, and you can turn up the HttpClient logging to see all of the data exchanged in your program. Alternatively, you can use something like Wireshark or Fiddler to watch your network traffic in real-time. This may give you a better idea of exactly what your browser is doing, versus what your program is doing.
As most of the suggested Java HTTP POST request code out there is not operational, I decided to give you my fully operational code that I'm sure you'll find helpful to create any Java-based POST request in the future.
This POST request is of multipart type to allow sending/uploading a file to the server.
Multipart request consist of a main header and a separator string called boundary to tell each part from the other (this separator will come in the stream with "--" (two dashes) string before it, and each part has its own small header to tell its type and some more meta-data.
My task was to create a PDF file using some online services but all the multipart POST examples just didn't do the trick...
I needed to pack an HTML document along with its pics, JS and CSS files in a ZIP/TAR file, upload it to an online html2pdf conversion service and get the result as a PDF document back to me as the response (stream) from the service.
The current service I've checked the using following code is: Htmlpdfapi.com but I'm sure that with minor adjustments you'll be able to use it with any other service.
The method call (for that service) looks something like:
[class instance name].sendPOSTRequest("http://htmlpdfapi.com/api/v1/pdf", "Token 6hr4-AmqZDrFVjAcJGykjYyXfwG1wER4", "/home/user/project/srv/files/example.zip", "result.pdf");
Here is my code that was checked and 100% works:
public void sendPOSTRequest(String url, String authData, String attachmentFilePath, String outputFilePathName)
{
String charset = "UTF-8";
File binaryFile = new File(attachmentFilePath);
String boundary = "------------------------" + Long.toHexString(System.currentTimeMillis()); // Just generate some unique random value.
String CRLF = "\r\n"; // Line separator required by multipart/form-data.
int responseCode = 0;
try
{
//Set POST general headers along with the boundary string (the seperator string of each part)
URLConnection connection = new URL(url).openConnection();
connection.setDoOutput(true);
connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);
connection.addRequestProperty("User-Agent", "CheckpaySrv/1.0.0");
connection.addRequestProperty("Accept", "*/*");
connection.addRequestProperty("Authentication", authData);
OutputStream output = connection.getOutputStream();
PrintWriter writer = new PrintWriter(new OutputStreamWriter(output, charset), true);
// Send binary file - part
// Part header
writer.append("--" + boundary).append(CRLF);
writer.append("Content-Disposition: form-data; name=\"file\"; filename=\"" + binaryFile.getName() + "\"").append(CRLF);
writer.append("Content-Type: application/octet-stream").append(CRLF);// + URLConnection.guessContentTypeFromName(binaryFile.getName())).append(CRLF);
writer.append(CRLF).flush();
// File data
Files.copy(binaryFile.toPath(), output);
output.flush();
// End of multipart/form-data.
writer.append(CRLF).append("--" + boundary + "--").flush();
responseCode = ((HttpURLConnection) connection).getResponseCode();
if(responseCode !=200) //We operate only on HTTP code 200
return;
InputStream Instream = ((HttpURLConnection) connection).getInputStream();
// Write PDF file
BufferedInputStream BISin = new BufferedInputStream(Instream);
FileOutputStream FOSfile = new FileOutputStream(outputFilePathName);
BufferedOutputStream out = new BufferedOutputStream(FOSfile);
int i;
while ((i = BISin.read()) != -1) {
out.write(i);
}
// Cleanup
out.flush();
out.close();
}
catch(Exception e)
{
e.printStackTrace();
}
}
I am currently writing a small web server, and I tested your request client. My server is receiving the following request:
User-Agent: Java/1.6.0_20
Host: localhost:1700
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive
Content-type: application/x-www-form-urlencoded
Content-Length: 287
name=M+V&affiliation=Company&email=m.v%40gmail.com&axialRise=0.34&helixDiameter=2.25&axialStiffness=1100&bendingStiffness=230&torsionalStiffness=460&nickStiffness=0.01&resolution=course&jsonUpload=C%3A%2FUsers%2FMarjie%2FDownloads%2Ftwisted_DNA_bundles%2Fmonotwist.L1.v1.json&type=square
You should check the format of the POST data you are sending, most probably it is not processed by the server as you would expect.
You should definitively use apaches HTTPClient for that job! It makes life much easier. Here is an example how to upload a file with apaches HttpClient.
byte[] data = outStream.toByteArray()
HttpClient client = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("http://localhost:8080/YourResource");
ByteArrayBody byteArrayBody = new ByteArrayBody(data, "application/json", "some.json");
MultipartEntity multipartEntity = new MultipartEntity();
multipartEntity.addPart("upload", byteArrayBody);
httpPost.setEntity( multipartEntity );
HttpResponse response = client.execute(httpPost);
Reader reader = new InputStreamReader(response.getEntity().getContent());
Let me know if you have further questions.
Here's an example I got working that uses apache httpclient. Also, don't forget to add these dependencies:
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.4.1</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpmime</artifactId>
<version>4.4.1</version>
</dependency>
The code:
HttpClient httpclient = HttpClientBuilder.create().build();
HttpPost httppost = new HttpPost(DataSources.TORRENT_UPLOAD_URL);
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.addPart("a_field_name", new FileBody(torrentFile));
HttpEntity entity = builder.build();
httppost.setEntity(entity);
HttpResponse response = httpclient.execute(httppost);
I am trying to send a multi part formdata post through my java code. Can someone tell me how to set Content Length in the following?? There seem to be headers involved when we use InputStreamBody which implements the ContentDescriptor interface. Doing a getContentLength on the InputStreamBody gives me -1 after i add the content. I subclassed it to give contentLength the length of my byte array but am not sure if other headers required by ContentDescriptor will be set for a proper POST.
HttpClient httpclient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(myURL);
ContentBody cb = new InputStreamBody(new ByteArrayInputStream(bytearray), myMimeType, filename);
//ContentBody cb = new ByteArrayBody(bytearray, myMimeType, filename);
MultipartEntity mpentity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
mpentity.addPart("key", new StringBody("SOME_KEY"));
mpentity.addPart("output", new StringBody("SOME_NAME"));
mpentity.addPart("content", cb);
httpPost.setEntity(mpentity);
HttpResponse response = httpclient.execute(httpPost);
HttpEntity resEntity = response.getEntity();
I'm the author of the ByteArrayBody class you have commented out.
I wrote it because I faced the same issue you did. The original Jira ticket is here: https://issues.apache.org/jira/browse/HTTPCLIENT-1014
So, since you already have a byte[], either upgrade HttpMime to the latest version, 4.1-beta1, which includes this class. Or copy the code from the Jira issue into your own project.
The ByteArrayBody class will do exactly what you need.
I'm trying out the twitter streaming api. I could succesfully filter tweets by using curl, as stated here:
curl -d #tracking http://stream.twitter.com/1/statuses/filter.json -u <user>:<pass>
where tracking is a plain file with the content:
track=Berlin
Now I tried to do the same thing in JavaSE, using Apache's HTTPComponents:
UsernamePasswordCredentials creds = new UsernamePasswordCredentials(<user>, <pass>);
DefaultHttpClient httpClient = new DefaultHttpClient();
httpClient.getCredentialsProvider().setCredentials(AuthScope.ANY, creds);
HttpPost httpPost = new HttpPost("http://stream.twitter.com/1/statuses/filter.json");
HttpParams params = new BasicHttpParams();
params = params.setParameter("track", "Berlin");
httpPost.setParams(params);
try {
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity entity = httpResponse.getEntity();
if (entity != null) {
InputStream instream = entity.getContent();
String t;
BufferedReader br = new BufferedReader(new InputStreamReader(instream));
while(true) {
t = br.readLine();
if(t != null) {
linkedQueue.offer(t);
}
}
}
} catch (IOException ioe) {
System.out.println(ioe.getMessage());
}
finally{
httpClient.getConnectionManager().shutdown();
}
When I run that, I get:
No filter parameters found. Expect at least one parameter: follow track
as a single entry in my linkedQueue. Seems the api wants the parameter in a different form, but cannot find any hint in the documentation. Can somebody share some experiences with the api or see any other problem with the code? Thanks!
EDIT
Putting the filter parameter into the params was a bad idea. As it's post data, it needs to be defined as an Entity before the request is being made:
StringEntity postEntity = new StringEntity("track=Berlin", "UTF-8");
postEntity.setContentType("application/x-www-form-urlencoded");
httpPost.setEntity(postEntity);
That's what I was doing wrong. Thanks Brian!
I suspect you need to post the data as the contents of your HTTP post. The man page for curl -d says:
(HTTP) Sends the specified data in a
POST request to the HTTP server, in
the same way that a browser does when
a user has filled in an HTML form and
presses the submit button. This will
cause curl to pass the data to the
server using the content-type
application/x-www-form-urlencoded.
so I believe you have to set that content type and put the contents of the tracking file in the body of your post.
