Hi,

Please find below some working code snippet for the starting of Activiti Process instance using REST.

Code:

String urlString = "http://localhost:8080/activiti-app/api/enterprise/process-instances";
 String propertiesJson = ""; //If you have any form fields to start the form
PostMethod mPost = null;
 HttpClient client = new HttpClient();
 mPost = new PostMethod(urlString); 
 String encoding = Base64.getEncoder().encodeToString("admin@app.activiti.com:admin".getBytes());
 mPost.setRequestHeader("Authorization", "Basic " + encoding);
 mPost.setRequestHeader("Content-Type", "application/json");
 mPost.setRequestEntity(new ByteArrayRequestEntity(propertiesJson.getBytes()));
 int statusCode = client.executeMethod(mPost);
 System.out.println("Response Code:::"+statusCode);‍‍‍‍‍‍‍‍‍‍‍

===========================================

Imports:

import org.apache.commons.httpclient.HttpClient;
import java.util.Base64;
import org.apache.commons.httpclient.methods.PostMethod;‍‍‍

Hope this helps.

Thanks,

Naveen
