Ignore the cookies part.

pradeep · September 28, 2017, 4:53pm

Is this section right? I wanted to embed the file content here directly. There is no file from which I can read the xml.

For the above request I get error

{
    "type": "RestException",
    "message": "multipart/form-data cannot be processed"
}

How to make this work?

StephenOTT · September 28, 2017, 5:58pm

Can you send a screenshot of your postman setup.
Can you try with the raw curl in terminal.

pradeep · September 28, 2017, 7:13pm

Not sure about what content type I should mention in the last multipart form

Content-Disposition: form-data; name=“MyBPMNFileName.bpmn”
Content-Type:

In the example provided in camunda docs there is no content type (Post Deployment | docs.camunda.org). I tried application/octet-stream and application/xml but didn’t work.

I did make this work from postman using form-data option by selecting the local file but I wanted to use this rest api just with the file content rather than a saved file

Your post man should look like this. And make sure to select your bpmn file in the last row.

pradeep · September 28, 2017, 7:26pm

As I mentioned already in my previous reply that I did made this work using form data option in postman. What I was looking for is a way to use this rest api without having a file but just with the bpmn xml content. Postman or javascript is not an option may be for my use case. I will send the XML to the backend which in turn deploy the xml using java API. Hope it works.

Thanks a lot @StephenOTT

StephenOTT · September 28, 2017, 7:30pm

@pradeep take a look at: https://github.com/StephenOTT/ProcessProjectTemplate

There is a jenkins file that does a deployment for you when you commit the repo that holds the bpmn and related files. all controlled through the [env]_deploy.json files.

May be of more interest for you if you are looking to deploy the xml. You can commit to a GIT repo (for version control) and have to deploy to your camunda server.

RodrigoPLpz · April 22, 2020, 10:39pm

Hi, I new and I’m practicing whith Learn Camunda with Nial (Camunda Rest API Tutorial). I had the same error. My fault it was that key and value were in different places and there haven’t been in the same line.

LSchoenfeld · August 4, 2022, 12:12pm

Hi @RodrigoPLpz,

Deploying a bpmn file via REST API with Postman worked so very well for me:

Make the following key/value entry in the "Headers" tab:

Key: “Content-Type”
Value: “multipart/form-data”

Hi all,

in an “integration component” (based on Spring Boot and Apache Camel) I am trying to implement a route for a deployment of a BPMN process definition (bpmn file). The special characteristic is that for the deployment a multipart form has to be created.

I have already deployed the used BPMN file using Postman in Camunda via REST API. There the deployment was successful.

Unfortunately the deployment in my Camel integration component is not successful. I get the following message from Camel (incl. stacktrace) when trying to execute the http request:

=> Do you know any advice?

My setup:

Camunda Platform v7.16 (as standalone engine)
Open JDK 11
Apache Camel v2.25.4
“Integration Component” (Maven Project/Spring Boot/Apache Camel)

Route:

@Override
	public void configure() throws Exception {
		from("file:target/data/bpmn-stateful?noop=true")
		.process(new BpmnStatefulDiagramsPrepForCamDeployment())
		.log("Content Type: ${header.Content-Type}")
		.log("${body}")
		.setHeader("CamelHttpMethod",constant("POST"))
		.log("${header.CamelHttpMethod} ${header.CamelFileName} to 'Create Deployment'")
		.to(wfms_rest_api_endpoint+"/deployment/create")
		.log("HTTP response status:"+header("HTTP_RESPONSE_CODE"))
		.log(LoggingLevel.DEBUG, "HTTP response body:\n${body}");
	}

Processor “BpmnStatefulDiagramsPrepForCamDeployment”:

@Override
	public void process(Exchange exchange) throws Exception {
		
		//Determine bpmn file from Camel Exchange (Message):
		File bpmnFile = exchange.getMessage().getBody(File.class);
				
		//Encode the file and other relevant parts for Camunda Deployment as a multipart entity:
		StringBody deploymentName = new StringBody(bpmnFile.getName(), 
                                                                                             ContentType.TEXT_PLAIN);
		FileBody bpmnFileBody = new FileBody(bpmnFile,ContentType.DEFAULT_BINARY);
		StringBody enableDuplicateFiltering = new StringBody("false", ContentType.TEXT_PLAIN);
		StringBody deployChangedOnly = new StringBody("false", ContentType.TEXT_PLAIN);
		
		MultipartEntityBuilder entity = MultipartEntityBuilder.create()
		  .addPart("deployment-name",deploymentName)
		  .addPart("enable-duplicate-filtering", enableDuplicateFiltering)
	         .addPart("deploy-changed-only", deployChangedOnly)
	         .addPart("data",bpmnFileBody);
		 
		HttpEntity httpEntity = entity.build();
				
	   // Set multipart entity as the message’s body:	
	    exchange.getMessage().setHeader(Exchange.CONTENT_TYPE, 
                                                                    httpEntity.getContentType().getValue());
		exchange.getMessage().setBody(httpEntity.getContent());
				
	}

This is what the generated Camel body looks like (log output):

I have already studied the following help pages:

Apache Camel multipart route: java - Apache Camel multipart route - Stack Overflow
Camel send multipart/form-data request: java - Camel send multipart/form-data request - Stack Overflow

Any timely advice would be greatly appreciated!

LSchoenfeld · August 9, 2022, 12:10pm

Hi @Niall,

do you know any advice regarding my post of 04.08.22 (see above)?

Many thanks for your support in advance!

Nele · August 25, 2022, 5:06pm

Hey @LSchoenfeld,

if the REST endpoint is working, and I assume it does as you tested it with Postman, the problem is within the implementation of the REST call in your java application. Unfortunately, I am not familiar with Camel. Is there a reason why you use Camel for the Deployment? You could also deploy the diagram by using SpringBoot, for example.

Kind regards
Nele

LSchoenfeld · August 28, 2022, 1:17pm

Hi @Nele,

thank you very much for your answer.

Your assumption is correct: the REST endpoint is running.

I am using a specific architecture here. Therefore I deploy an integration process from another component to a remote application with embedded Camunda Process Engine. For integration pattern I am using Apache Camel. Deployment within the same application of process definitions is known to me, but not possible because of the particular architecture.

I suppose that the generated multipart form data is not accepted by the Camunda Engine via REST. Please have a look at this part:

The XML part in the code excerpt above (Multipart form data) is the BPMN file for testing purposes.

Is there anything special I need to consider when passing the deployment artifact to Camunda REST API? - Or in other words: What do I need to consider when deploying via the Camunda REST API Multipart form data)?

How would you deploy processes/decisions in Java as multipart form data via Camunda REST API?

Best Regards and thanks
