How to deploy a BPMN Model

After you have created a model with the Imixs-BPMN modeler you can deploy the model. The Imixs-Workflow Rest API provides a convenient way to upload a BPMN model or to verify the deployment status of BPMN models. Make sure that your Imixs-Workflow instance is up and running and the Imxis-Workflow Rest Service is deployed on your server. (See the deployment section how to deploy the Imixs-Workflow engine into a server.)

The Imixs-Workflow Model Rest Service is available under the following resource URL:

http://localhost:8080/api/model/

where ‘/workflow/’ is the context root of your workflow application and ‘/api/’ is the context of the Imixs-Workflow Rest Services. See the section model rest service for general information about the Imixs-Workflow Rest API.

Deploy a Model

To deploy a BPMN model you can use the command-line tool curl to upload a Imixs BPMN 2.0 model into a Imixs-Workflow instance. See the following example:

curl --user admin:adminpassword --request POST -Tticket.bpmn http://localhost:8080/api/model/bpmn

This example deploys the bpmn file ‘ticket.bpmn’ into the Imixs-Workflow Instance ‘http://localhost:8080/workflow/’. The result of the deployment can be verified in the server log:

09:20:47,611 INFO  [org.imixs.workflow.bpmn.BPMNParser] (default task-3) BPMN Model parsed in 12ms

You can also verify the current status of deployed models by calling the model Rest Service in your Web Browser:

http://localhost:8080/api/model/

Delete a model

To delete a specific model version the Imxis-Rest API provides a DELETE command

curl --user admin:adminpassword --request DELETE http://localhost:8080/workflow/rest-service/model/[VERSION]

How to Deploy a Model from a Java Application

You can also use the Imixs ModelService to deploy a BPMN model programtically. In this case you call the Model Service EJB form your application to deploy a model. The following example demonstrates the API call:

import org.imixs.workflow.bpmn.BPMNModel;
import org.imixs.workflow.bpmn.BPMNParser;
import org.imixs.workflow.jee.ejb.ModelService;
....

@EJB
protected ModelService modelService;

.....
// open a inputStream of the model file
InputStream inputStream = getClass().getResourceAsStream(
			"/bpmn/ticket.bpmn");
// parse and import the model....
BPMNModel model = BPMNParser.parseModel(file.getData(), "UTF-8");
modelService.importBPMNModel(model);
...
