I dont have WSDL just having Sample request and response,Is it possible to consume JAX-WS Web service without having WSDL in J2EE environment?
In this case, SAAJ could be a possible solution, it's a low level API that would let you to construct and send SOAP messages to any endpoint.
MessageFactory factory = MessageFactory.newInstance();
SOAPMessage message = factory.createMessage();
SOAPBody body = message.getSOAPBody();
QName bodyName = new QName("http://example.org/", "HelloWorld", "hello");
SOAPBodyElement bodyElement = body.addBodyElement(bodyName);
SOAPConnectionFactory factory = SOAPConnectionFactory.newInstance();
SOAPConnection connection = factory.createConnection();
SOAPMessage response = connection.call(message, "http://example.org/soap");

As part of a user action, we are using the MS Graph Java SDK to first list all permissions of a file, then iterating over the list of permissions to delete each one individually. This seems to have some performance issues. We were wondering if there is any way to batch the calls using the IGraphServiceClient.
Relevant APIs used:
https://learn.microsoft.com/en-us/graph/api/driveitem-list-permissions?view=graph-rest-1.0&tabs=http
https://learn.microsoft.com/en-us/graph/api/permission-delete?view=graph-rest-1.0&tabs=http
You can make batch requests.
1. Create MSBatch Request Steps (examples below)
Request requestGetMe = new Request.Builder().url("https://graph.microsoft.com/v1.0/me/").build();
List<String> arrayOfDependsOnIdsGetMe = null;
MSBatchRequestStep stepGetMe = new MSBatchRequestStep("1", requestGetMe, arrayOfDependsOnIdsGetMe);
Request requestGetMePlannerTasks = new Request.Builder().url("https://graph.microsoft.com/v1.0/me/planner/tasks").build();
List<String> arrayOfDependsOnIdsGetMePlannerTasks = Arrays.asList("1");
MSBatchRequestStep stepMePlannerTasks = new MSBatchRequestStep("2", requestGetMePlannerTasks, arrayOfDependsOnIdsGetMePlannerTasks);
String body = "{" +
"\"displayName\": \"My Notebook\"" +
"}";
RequestBody postBody = RequestBody.create(MediaType.parse("application/json"), body);
Request requestCreateNotebook = new Request
.Builder()
.addHeader("Content-Type", "application/json")
.url("https://graph.microsoft.com/v1.0/me/onenote/notebooks")
.post(postBody)
.build();
MSBatchRequestStep stepCreateNotebook = new MSBatchRequestStep("3", requestCreateNotebook, Arrays.asList("2"));
2. Create MSBatch Request Content and get content
List<MSBatchRequestStep> steps = Arrays.asList(stepGetMe, stepMePlannerTasks, stepCreateNotebook);
MSBatchRequestContent requestContent = new MSBatchRequestContent(steps);
String content = requestContent.getBatchRequestContent();
3. Make call to $batch endpoint
OkHttpClient client = HttpClients.createDefault(auth);
Request batchRequest = new Request
.Builder()
.url("https://graph.microsoft.com/v1.0/$batch")
.post(RequestBody.create(MediaType.parse("application/json"), content))
.build();
Response batchResponse = client.newCall(batchRequest).execute();
4. Create MSBatch Response Content
MSBatchResponseContent responseContent = new MSBatchResponseContent(batchResponse);
Response responseGetMe = responseContent.getResponseById("1");
// Use the response of each request
I am newbie to web service. Due to requirement I have to send a file[most probably in txt format] to server through REST web service.
I am getting the exception like below.
MessageBodyWriter not found for media type=application/json, type=class gvjava.org.json.JSONObject, genericType=class gvjava.org.json.JSONObject.
Here is my web service method.
#Path("{c}")
#POST
#Produces(MediaType.APPLICATION_JSON)
#Consumes(MediaType.APPLICATION_JSON)
public String convert(#PathParam("c") JSONObject object) throws JSONException {
String result = "";
return "<ctofservice>" + "<ctofoutput>" + result + "</ctofoutput>" + "</ctofservice>";
}
Now client code is like below
JSONObject data_file = new JSONObject();
data_file.put("file_name", uploadFile.getName());
data_file.put("description", "Something about my file....");
data_file.put("file", uploadFile);
Client client = ClientBuilder.newClient();
webTarget = client.target(uploadURL).path("ctofservice").path("convert");
Response value = webTarget.request(MediaType.APPLICATION_JSON_TYPE)
.post(Entity.entity(data_file,MediaType.APPLICATION_JSON_TYPE),
Response.class);
Please help me with this.
Thanks in advance.

As suggested by peeskillet in the answer below, I tried to send file through multipart. Still I am facing exception of no octet stream found.
Below is my rest api
#Path("{c}")
#POST
#Consumes(MediaType.MULTIPART_FORM_DATA)
public Response convert(#FormDataParam("file") FormDataContentDisposition file) {
String result = "";
Some operation with attached parameter ...
return Response.status(200).entity(result).build();
}
Here is my test client
FormDataMultiPart multiPart = new FormDataMultiPart();
multiPart.setMediaType(MediaType.MULTIPART_FORM_DATA_TYPE);
FileDataBodyPart fileDataBodyPart = new FileDataBodyPart("file",
uploadFile,MediaType.APPLICATION_OCTET_STREAM_TYPE);
multiPart.bodyPart(fileDataBodyPart);
Client client = Client.create();
WebResource webResource = client
.resource(uploadURL).path("ctofservice");
ClientResponse response = webResource.accept("application/json")
.post(ClientResponse.class,multiPart);
if (response.getStatus() != 200) {
throw new RuntimeException("Failed : HTTP error code : "
+ response.getStatus());
}
And I am getting the exception below
I am not able to understand why I need to send data as MediaType.APPLICATION_OCTET_STREAM_TYPE ? As I have used multipart as media type before ...
I appreciate your help..
Without needing to configuring anything else, the easiest way to get around this is to just use a String instead of the actual JSONObject (i.e. just passing toString())
.post(Entity.json(data_file.toString()))
The problem with using JSONObject is that there is no provider that knows how to handle the conversion. You will have the same problem on the server side, where there is no provider to handle the conversion to JSONObject. So you will need to just do
#POST
public Response post(String json) {
JSONObject jsonObject = new JSONObject(json);
}
If you really want to be able to just use JSONObject without needing to use a String, then you should check out this post.
As an aside, this is not valid JSON (it's XML)
"<ctofservice>" + "<ctofoutput>" + result + "</ctofoutput>" + "</ctofservice>"
but you are saying that the endpoint returns JSON
I am trying to get activity stream of my jira instance using the below api and it is not working , can anybody point me in the right direction ?
You should check this page out: https://developer.atlassian.com/docs/atlassian-platform-common-components/activity-streams/consuming-an-activity-streams-feed
The Atom feed of the activity stream works well only if you also log in in your feed reader.
Here is an example of consuming the activity stream through the Jira API using Basic Authentication. This is in C#, but the basic pattern can be applied anywhere:
string myJiraUsername = "username";
string myJiraPassword = "password"; //or API token
string authenticationHeaderValue = Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(myJiraUsername + ":" + myJiraPassword));
System.Net.Http.HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", authenticationHeaderValue);
Task<HttpResponseMessage> task = client.GetAsync("https://mycompany.atlassian.net/activity");
task.Wait();
HttpResponseMessage response = task.Result;
string resultOfApiCall = "";
if (response.IsSuccessStatusCode)
{
resultOfApiCall = response.Content.ReadAsStringAsync().Result;
Console.WriteLine("This was returned by your API request:\n" + resultOfApiCall);
}
I'm using the DotNetOpenAuth framework which has been great to get up to speed with consuming data.
I'm using it to talk to LinkedIn and am having trouble figuring out the correct approach to posting/sharing information to the site. Here is the reference I am using - http://developer.linkedin.com/documents/share-api
When I execute the below code I always get the below error responses;
Error occurred while sending a direct message or getting the response.
The remote server returned an error: (400) Bad Request.
I am using Oauth v1.0a.
Here is my code;
try
{
HttpDeliveryMethods resourceHttpMethod = HttpDeliveryMethods.PostRequest | HttpDeliveryMethods.AuthorizationHeaderRequest;
string xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><share><comment>83% of employers will use social media to hire: 78% LinkedIn, 55% Facebook, 45% Twitter [SF Biz Times] http://bit.ly/cCpeOD</comment>";
xml += "<content><title>Survey: Social networks top hiring tool - San Francisco Business Times</title>";
xml += "<submitted-url>http://sanfrancisco.bizjournals.com/sanfrancisco/stories/2010/06/28/daily34.html</submitted-url>";

var multiparts = new List<MultipartPostPart>();
MultipartPostPart part = MultipartPostPart.CreateFormPart("body", xml);
part.PartHeaders[HttpRequestHeader.ContentType] = "application/xml";
multiparts.Add(part);
var resourceEndpoint = new MessageReceivingEndpoint("http://api.linkedin.com/v1/people/~/shares", resourceHttpMethod);
HttpWebRequest request = consumer.PrepareAuthorizedRequest(resourceEndpoint, accessToken, multiparts);
request.ServicePoint.Expect100Continue = false;
IncomingWebResponse response = consumer.Channel.WebRequestHandler.GetResponse(request);
this.resultsBox.Text = response.GetResponseReader().ReadToEnd();
}
catch (Exception ex)
{
}
Thanks
Forgot to write back on this, talking to someone from a vintage google newsgroup I got the direction I needed but wanted to verify the solution before posting.
The big thing I was screwing up on was adding the multipart data prior to sending the request data as opposed to constructing the request myself and writing the new content to the stream.
I'm new to using OAuth and REST so I don't know all the ins and outs, suffice to say I've validated this code against both the LinkedIn and Twitter REST APIs.
Here is the new CODE;
try
{
Encoding encoder = Encoding.ASCII;
HttpDeliveryMethods resourceHttpMethod = HttpDeliveryMethods.PostRequest | HttpDeliveryMethods.AuthorizationHeaderRequest;
byte[] bytes = encoder.GetBytes(xd.OuterXml.ToString());
var resourceEndpoint = new MessageReceivingEndpoint(ResourceURL, resourceHttpMethod);
HttpWebRequest request = _consumer.PrepareAuthorizedRequest(resourceEndpoint, _manager.AccessToken);
request.ServicePoint.Expect100Continue = false;
request.Method = "POST";
request.ContentLength = bytes.Length;
request.ContentType = "application/xml";
using (System.IO.Stream requestStream = request.GetRequestStream())
{
requestStream.Write(bytes, 0, bytes.Length);
}
IncomingWebResponse response = _consumer.Channel.WebRequestHandler.GetResponse(request);
ret = true;
}
catch (Exception ex)
{
_Logger.Error(OpenLogger.FormatException(ex));
}
I am trying to generate the OData Proxy for the service : http://services.odata.org/Northwind/Northwind.svc/$metadata
I am using System.Data.Services.Design.EntityClassGenerator for generating the OData proxy.
When I instantiate the EntityClassGenerator and call GenerateCode the output has no errors. But there is no code in the generated proxy code.
The same code works for my own service. But when I point it to any external service the EntityClassGenerator is not working.
Here is the code :
HttpWebRequest webRequest = (HttpWebRequest)HttpWebRequest.Create(metadataEndpoint);
webRequest.Method = "GET";
webRequest.ContentType = "text/xml;encoding='utf-8";
webRequest.Proxy = (proxy != null) ? proxy : WebRequest.DefaultWebProxy;
using (WebResponse response = webRequest.GetResponse())
{
string xml = string.Empty;
XmlReaderSettings settings = new XmlReaderSettings();
using (TextReader reader = new StreamReader(response.GetResponseStream()))
{
xml = reader.ReadToEnd();
using (XmlTextReader sourceReader = new XmlTextReader(reader))
{
using (StringWriter targetWriter = new StringWriter())
{
// Generate the OData End point proxy.
EntityClassGenerator entityGenerator = new EntityClassGenerator(LanguageOption.GenerateCSharpCode);
entityGenerator.OnPropertyGenerated += new EventHandler<PropertyGeneratedEventArgs>(entityGenerator_OnPropertyGenerated);
IList<System.Data.Metadata.Edm.EdmSchemaError> errors = entityGenerator.GenerateCode(sourceReader, targetWriter, namespacename);
entityGenerator.OnPropertyGenerated -= new EventHandler<PropertyGeneratedEventArgs>(entityGenerator_OnPropertyGenerated);
odataProxyCode = targetWriter.ToString();
}
}
}
}
I found the code in the question to be a useful starting point for doing exactly what the OP was asking. So even though the OP doesn't accept answers, I'll describe the changes I made to get it to work in case it is useful to someone else.
Removed the xml = reader.ReadToEnd(); call. I assume that was for debugging purposes to look at the response from the web request, but it had the result of "emptying" the reader object of the response. That meant that there was nothing left in the reader for the GenerateCode call.
The important one: Changed the use of EntityClassGenerator to System.Data.Services.Design.EntityClassGenerator. In the code below, I included the entire name space for clarity and specificity. Based on the code in the question, it appears the OP was probably using System.Data.Entity.Design.EntityClassGenerator. I used .NET Reflector to examine datasvcutil.exe, which is a command-line utility that can generate the proxy classes. I saw that it referenced the generator in that other name space.
For figuring out the problems, I dumped the errors from the GenerateCode call. One could examine them in the debugger, but some kind of automated checking of them would be needed regardless.
Here is what I ended up with:
HttpWebRequest webRequest = (HttpWebRequest)HttpWebRequest.
Create("http://services.odata.org/Northwind/Northwind.svc/$metadata");
webRequest.Method = "GET";
webRequest.ContentType = "text/xml;encoding='utf-8";
webRequest.Proxy = WebRequest.DefaultWebProxy;
using (WebResponse response = webRequest.GetResponse())
{
using (TextReader reader = new StreamReader(response.GetResponseStream()))
{
using (XmlTextReader sourceReader = new XmlTextReader(reader))
{
using (StringWriter targetWriter = new StringWriter())
{
// Generate the OData End point proxy.
System.Data.Services.Design.EntityClassGenerator entityGenerator =
new System.Data.Services.Design.EntityClassGenerator(
System.Data.Services.Design.LanguageOption.GenerateCSharpCode);
IList<System.Data.Metadata.Edm.EdmSchemaError> errors =
entityGenerator.GenerateCode(sourceReader, targetWriter,
"My.Model.Entities");
foreach (System.Data.Metadata.Edm.EdmSchemaError error in errors)
Console.WriteLine("{0}: {1}", error.Severity.ToString(), error.Message);
string odataProxyCode = targetWriter.ToString();
}
}
}
}
