Unable to deploy the bpmn file using activiti rest api post

[jaikrishna]

Hi ,

I have been trying to deploy the file through activiti rest api post ..
But I am not able to do it ..
Please help me ..
I have attached the code ..

public class repo
{   
private static String REST_URI = "http://localhost:8080/activiti-rest/service/repository";

private static ClientResource getClientResource(String uri)
{
ClientResource resource = new ClientResource(uri);
resource.setChallengeResponse(ChallengeScheme.HTTP_BASIC,"kermit", "kermit");
return resource;
}

public static void postDeployments() throws JSONException,IOException {   



String postdeploymnet = REST_URI+"/deployments";






Path path = Paths.get(".\\src\\main\\resources\\diagrams\\SimpleLeaveProcess.bpmn");
String name = "SimpleLeaveProcess.bpmn";
String originalFileName = "SimpleLeaveProcess.bpmn";
String contentType = "";
byte[] content = null;
try {
content = Files.readAllBytes(path);
} catch (final IOException e) {
}
MultipartFile result = new MockMultipartFile(name,originalFileName, contentType, content);


Representation response1 = getClientResource(postdeploymnet).post(result, MediaType.MULTIPART_FORM_DATA);
}
}

Hi jaikrishna,
Do you have a error in the log or any other relevant information which can help us understand what's happening?

[jaikrishna]

After the line "Representation response1 = getClientResource(postdeploymnet).post(result, MediaType.MULTIPART_FORM_DATA);" , nothing is getting executed ..
Am I doing the file conversion to multipart format right ? the way I am calling the rest api post , arguments is that all right ?
I don't know where I am making mistake .. Please help me .
If you have the code for file deploy through activiti post , please share that as well..
Please guide

Check http://www.codejava.net/java-se/networking/upload-files-by-sending-multipart-request-programmaticall..., that's what i use.

[jaikrishna]

How do I add the username and password in the code ?
Can you please tell me how to do that in the same link which you had posted

[jbarrez]

That's standard basic auth … nothing fancy about that at all .So simply by setting the Authorization header correctly (  httpConn.setRequestProperty("Authorization", credentials):smileywink:

[jaikrishna]

I am getting status returned as 401 .. I used the same multipartutility class file which you had mentioned .. I had added the credentials in setrequestproperty .. What might be the reason ? My url is right .. And I am able to deploy properly using rest client as well .. Programmatically while doing getting the error .. Please help me ..

[jaikrishna]

any update on this ?

Can't say much without you actually posting what you have currently…. it should be pretty straight forward Java, nothing special about that.
