jbpm 6 remote rest api integration with spring boot - rest

Question

I am trying to create a jbpm+angular+springboot application .
The idea of api documentation is here :
https://developer.jboss.org/people/bpmn2user/blog/2014/01/11/jbpm6--angular-js-web-example
The remote integration documentation:
http://docs.jboss.org/jbpm/v6.0/userguide/jBPMRemoteAPI.html
My spring boot controller:
package org.jbpm.spring.boot;
import java.net.URL;
import org.jbpm.services.api.model.UserTaskInstanceDesc;
import org.kie.api.runtime.KieSession;
import org.kie.api.runtime.manager.RuntimeEngine;
import org.kie.api.runtime.process.ProcessInstance;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
#Controller
#RequestMapping("/task")
public class RestController {
#RequestMapping(value = "/show", method = RequestMethod.GET)
public UserTaskInstanceDesc getTask(#RequestParam String id) {
String deploymentId="id";
URL deploymentUrl=new URL("http://localhost:8080/jbpm-console/");
String user="user";
String password="password";
RemoteRestSessionFactory restSessionFactory
= new RemoteRestSessionFactory(deploymentId, deploymentUrl, user, password);
RuntimeEngine engine = restSessionFactory.newRuntimeEngine();
KieSession ksession = engine.getKieSession();
ProcessInstance processInstance = ksession.startProcess("org.jbpm.humantask");
}
}
for some reason "RemoteRestSessionFactory" cant be resolved as type my pom looks like this:

How can i resolve this?

Answer 1

You are missing kie-services-client library in pom.xml.
<dependency>
<groupId>org.kie.remote</groupId>
<artifactId>kie-services-client</artifactId>
<version>6.1.0.Final</version>
</dependency>
The class RemoteRestSessionFactory is replaced with RemoteRestRuntimeFactory in latest releases. If you still want to use RemoteRestSessionFactory, then you should use <version>6.0.0.CR5</version>. But it is not recommended.

Answer 2

You are not importing org.kie.services.client.api.RemoteRestSessionFactory in you RestController
You are not importing org.kie:kie-server-client:6.2.0.Final in your pom file.
