JBPM : POST request for execute process go wrong

Question

I am new to jBPM.

I reference jbpm.org for tutorial. And I tried " My First Business Application " example. It is OK.

And then I tried the next tutorial " Business Application with Business Asset ". The first steps are going well. I successfully done installation of jBPM Console, drawing business process asset in KIE process and starting the application are going well.

And I tested according to reference. I got a problem for sending POST request to my application. I use Chrome Postman client for sending POST request.

In tutorial, they give the following link to make POST request.

http://localhost:8090/rest/server/containers/business-application-kjar/processes/business-application-kjar.process/instances

I do but I always get " 415 Unsupported Media Type " in every time. I also research for error. I can't find anywhere.

Please help me.

I am trouble for continue the next examples.

I want to know is any way to continue or am I wrong in sending request.

Thanks.

Answer 1

415 - Unsupported Media Type error occurs when the request is in a format not supported by the server.

Add the following http header parameters to your request.

Accept: application/json

Content-type: application/json

X-KIE-ContentType: JSON
