Question

我尝试使用jBPM创建进程，我使用Jboss 7.1服务器，我为eclipse Kepler安装了jbpm插件，并添加了jar。现在我创建一个简单的hello world项目，但总是出错：

java.lang.RuntimeException: RuntimeManagerFactory was not initialized, see previous errors
    at org.kie.api.runtime.manager.RuntimeManagerFactory$Factory.get(RuntimeManagerFact     ory.java:112)
 at org.jbpm.test.JbpmJUnitBaseTestCase.<init>   (JbpmJUnitBaseTestCase.java:119)
    at org.jbpm.test.JbpmJUnitBaseTestCase.<init>    (JbpmJUnitBaseTestCase.java:157)
    at com.sample.ProcessTest.<init>(ProcessTest.java:54)
 at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)

请帮忙吗？

这是主要代码：

import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
 import org.jbpm.test.JBPMHelper;
import org.kie.api.KieBase;
 import org.kie.api.KieServices;
import org.kie.api.runtime.KieContainer;
import org.kie.api.runtime.KieSession; 
import org.kie.api.runtime.manager.RuntimeEngine;
import org.kie.api.runtime.manager.RuntimeEnvironmentBuilder;
import org.kie.api.runtime.manager.RuntimeManager;
import org.kie.api.runtime.manager.RuntimeManagerFactory;
import org.kie.api.task.TaskService;
import org.kie.api.task.model.TaskSummary;

public class ProcessMain {

public static void main(String[] args) {
    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();
    TaskService taskService = engine.getTaskService();

    ksession.startProcess("com.sample.bpmn.hello");

    // let john execute Task 1
    List<TaskSummary> list = taskService.getTasksAssignedAsPotentialOwner("john", "en-UK");
    TaskSummary task = list.get(0);
    System.out.println("John is executing task " + task.getName());
    taskService.start(task.getId(), "john");
    taskService.complete(task.getId(), "john", null);

    // let mary execute Task 2
    list = taskService.getTasksAssignedAsPotentialOwner("mary", "en-UK");
    task = list.get(0);
    System.out.println("Mary is executing task " + task.getName());
    taskService.start(task.getId(), "mary");
    taskService.complete(task.getId(), "mary", null);

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

private static RuntimeManager createRuntimeManager(KieBase kbase) {
    JBPMHelper.startH2Server();
    JBPMHelper.setupDataSource();
    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:example:1.0");
}

  }

我有同样的问题，我解决了！

如果您关注RuntimeEnvironmentBuilder source code ，您会注意到方法 Factory.get（）会抛出您获取的错误 RuntimeEnvironmentBuilderFactory < / b>是空的！

但它如何构建该实例？它使用此类 org.jbpm.runtime.manager.impl.RuntimeEnvironmentBuilder 因此，在类路径中没有此类，实例无法构造并保持为空。

您可以在jbpm-runtime-manager-6.4.0.Final.jar或您选择的任何其他jar中找到此类。

希望这有帮助！
