The process works. I ran it through workbench. But the runs tests fall.
I'm trying this:

  @Test
    public void test() {

        KieServices ks = KieServices.Factory.get();
        KieContainer kContainer = ks.getKieClasspathContainer();
        KieBase kbase = kContainer.getKieBase("kbase");

        RuntimeManager manager = createRuntimeManager(kbase);
        RuntimeEngine engine = manager.getRuntimeEngine(null);

        KieSession ksession = engine.getKieSession();
        ksession.getWorkItemManager().registerWorkItemHandler("Service Task", new ServiceTaskHandler());
        ProcessInstance pInstance = ksession.startProcess("project.Main");
        //assertEquals(ProcessInstance.STATE_COMPLETED, pInstance.getState());


        manager.disposeRuntimeEngine(engine);
        System.exit(0);
    }

    private static RuntimeManager createRuntimeManager(KieBase kbase) {
        JBPMHelper.startH2Server();
        JBPMHelper.setupDataSource();
        System.out.println(JBPMHelper.getProperties());
        EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.persistence.jpa");

        RuntimeEnvironmentBuilder builder = RuntimeEnvironmentBuilder.Factory.get()
                .newDefaultBuilder().entityManagerFactory(emf)
                .knowledgeBase(kbase);
        return RuntimeManagerFactory.Factory.get()
                .newSingletonRuntimeManager(builder.get(), "com.sample.bpm.mig:project:1.0");
    }

Error

The webservice

package com.sample.bpm.testservice;

import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.xml.ws.ResponseWrapper;

@WebService(name = "fuseMock",
        targetNamespace = "urn:com.sample.bpm.testservice:0.1"
)
public interface FuseMock {

    long getUcdbId();

    void save(@WebParam(name = "state") String state);

    void setUcdbId(@WebParam(name = "ucdbId") Long ucdbId);

    void test();

    void test2(@WebParam(name = "in") String in);

    void test3(@WebParam(name = "in1") String in1, @WebParam(name = "in2") String in2);

}

How can it be a substitute for the class FuseMock?
