how to invoke the static java calss when the method name mentioned in constructor

Hi Experts,

My Test class having

      hashMap.put("file", bytesArray);
      hashMap.put("filename", fname);
      hashMap.put("event", event);
      ObjectMapper objectMapper = new ObjectMapper();
      String requestBody = objectMapper.writeValueAsString(hashMap);      
      //url:http://10.0.9.1:8080/global/uploadAndGetDocID

Open in new window

my base uri is -

http://10.0.9.1:8080/global
method name is uploadAndGetDocID

Open in new window

i have constructor class

i want to call this method uploadAndGetDocID and from there
i want to invoke the postMultipartFormDataAsJson method and get the response.

this method not specified any where but mentioned in constructor as below
_uriBuilder = _uriBuilder.path("uploadAndGetDocID");

Static class: 

public static class UploadAndGetDocID {

            private com.sun.jersey.api.client.Client _client;
            private UriBuilder _uriBuilder;
            private Map<String, Object> _templateAndMatrixParameterValues;

            private UploadAndGetDocID(com.sun.jersey.api.client.Client client, UriBuilder uriBuilder, Map<String, Object> map) {
                _client = client;
                _uriBuilder = uriBuilder.clone();
                _templateAndMatrixParameterValues = map;
            }

           
            public UploadAndGetDocID(com.sun.jersey.api.client.Client client, URI baseUri) {
                _client = client;
                _uriBuilder = UriBuilder.fromUri(baseUri);
                _uriBuilder = _uriBuilder.path("uploadAndGetDocID");
                _templateAndMatrixParameterValues = new HashMap<String, Object>();
            }

         

            public<T >T postMultipartFormDataAsJson(Object input, Class<T> returnType) {
                UriBuilder localUriBuilder = _uriBuilder.clone();
                com.sun.jersey.api.client.WebResource resource = _client.resource(localUriBuilder.buildFromMap(_templateAndMatrixParameterValues));
                com.sun.jersey.api.client.WebResource.Builder resourceBuilder = resource.getRequestBuilder();
                resourceBuilder = resourceBuilder.accept("application/json");
                resourceBuilder = resourceBuilder.type("multipart/form-data");
                com.sun.jersey.api.client.ClientResponse response;
                response = resourceBuilder.method("POST", com.sun.jersey.api.client.ClientResponse.class, input);
                return response.getEntity(returnType);
                
            }

        }

can some one suggest how to invoke it and get the response from postMultipartFormDataAsJson method

You need a Client as well as that to create an instance

hi
Can i create as below.

ClientConfig cc = new DefaultClientConfig();
 com.sun.jersey.api.client.Client createClientInstance = createClientInstance(cc);
private static com.sun.jersey.api.client.Client createClientInstance(ClientConfig cc) {
        return com.sun.jersey.api.client.Client.create(cc);
    }

CEHJ

Well you don't want to be doing all that kind of stuff outside a method, but that general approach should be OK.
A question: you're not by any chance working with API source code are you?

Hi cehj,

I am gettiing error while invoking the below code:

URI obj = null;
      try {
         obj = new URI("http://10.0.9.1:8080/global/uploadAndGetDocID");
      } catch (URISyntaxException e) {
         e.printStackTrace();
      }
       ClientConfig cc = new DefaultClientConfig();
        com.sun.jersey.api.client.Client createClientInstance = createClientInstance(cc);
        UploadAndGetDocID uploadDocId = new UploadAndGetDocID(createClientInstance, obj);
        String postMultipartFormDataAsJson = uploadDocId.postMultipartFormDataAsJson(hashMap, String.class);
       System.out.println("postMultipartFormDataAsJson "+postMultipartFormDataAsJson);

com.sun.jersey.api.client.ClientHandlerException: com.sun.jersey.api.client.ClientHandlerException: A message body writer for Java type, class java.util.HashMap, and MIME media type, multipart/form-data, was not found.

hi cehj,

i worked on api code the jersey api i didnt touched till now.

CEHJ

I don't know this API (i can't even find the link to the javadoc) but i would guess you either need to find an implemented writer or define a custom one

I'm also going to take a guess that it would be easier to do if you were to write a proper bean rather than using a Map. e.g.

public class FileData {
    private byte[] data;
    private String fileName;
    private String event;

    public FileData() {
    }

    public FileData(byte[] data, String fileName, String event) {
        this.data = data;
        this.fileName = fileName;
        this.event = event;
    }

    public byte[] getData() {
        return this.data;
    }

    public String getFileName() {
        return this.fileName;
    }

    public String getEvent() {
        return this.event;
    }

    public void setData(byte[] data) {
        this.data = data;
    }

    public void setFileName(String fileName) {
        this.fileName = fileName;
    }

    public void setEvent(String event) {
        this.event = event;
    }

    public String toString() {
        return String.format("%s=%s,%s=%s,%s=%s", "data", data, "fileName", fileName, "event", event);
    }
}

hi cehj,

now i have changed map to bean class while hitting the service getting 500 error.

response.getStatus()//getting 500 error.

Restful webservices API
i am consuming restful post method/get method using java

CEHJ

That suggests that the URI is wrong or the service doesn't exist

srikotesh

ASKER

same requirement is availble in this link.

https://stackoverflow.com/questions/27609569/file-upload-along-with-other-object-in-jersey-restful-web-service

file uploading service i am trying

Service is available i am able to hit from postman and getting the response.

CEHJ

You've got the service running on your own web server then?

srikotesh

ASKER

Service is available i am able to hit from postman and getting the response.

CEHJ

I'm out of my depth now as i don't do REST

srikotesh

ASKER

CEHJ

But ... you've probably got the source of the service haven't you? If so, it would help to post it

CEHJ

Looking a little at the Jersey multipart implementation i see that your client is a long way off what is required (as was my guessed suggestion of using a bean)
In the distro, there's a test example in jersey/examples/multipart-webapp/src/test/java/org/glassfish/jersey/examples/multipart/webapp/MultiPartWebAppTest.java but with little or no commentary

Hi Cehj,

the static class which i shared in the above comment is the client source code-->UploadAndGetDocID.

CEHJ

OK but i'm not convinced it's up to date. Where did you get it from?

e.g. com.sun.jersey.api.client.WebResource no longer exists in the supported API:

https://eclipse-ee4j.github.io/jersey.github.io/apidocs/latest/jersey/index.html
I suspect that all the sun stuff is now superseded and unsupported

I have wadl uri-from that i have generated the client code with your help,in my previous question i have asked about
how to generate source code from wadl

CEHJ

There's some confusion then. Which API is being used here: Jersey, or something else?

srikotesh

ASKER

Jersey API is used to generate client code.

CEHJ

Right. Unfortunately it seems to be badly documented, with examples virtually non-existent

srikotesh

ASKER

i am also suspecting client generated code does not look like clean code.

CEHJ

Jersey API is used to generate client code.

Actually i don't think that's correct. I think it's Apache CXF

srikotesh

ASKER

But i have another wadl service request call.

this 2nd service is using to send msg(this different wadl)
below code is working for it.i am getting the response as well.but here i didnt used any client code.only with jerseyapi
i have called it is working.

ClientResponse response = webResource.accept("application/json")
                                 .header("Content-Type","multipart/form-data")
                                 .header("groupId","123")
                                 .type("application/json")
                                 .post(ClientResponse.class,request);

Open in new window

but for my first service i have to do the same way for file uploading.with out considering the staic class uploadgetdocid
with jersyapi can i call it in similar way?

Hi Cehj,

the below code is working to call services

Client client = ClientBuilder.newBuilder().register(MultiPartFeature.class).build();
         FileDataBodyPart filePart = new FileDataBodyPart("file", new File(fileUpload.getChannelFileName()));
         multipart = (FormDataMultiPart) formDataMultiPart.field("file", "key-file")
                     .field("filename", fileUpload.getChannelFileName())
                     .field("event", fileUploadRequest)
                     .bodyPart(filePart);
