使用与 zkoss 和 EJB 集成的 Jbpm 部署应用程序时出现以下错误。谁能帮忙？？？我正在使用 JBoss 7.1.1 最终版。

错误 ：

Unsatisfied dependencies for type [UserGroupCallback] with qualifiers [@Default] at injection point [[field] @Inject private org.jbpm.services.task.identity.AbstractUserGroupCallbackDecorator.userGroupCallback]

这是堆栈跟踪：

你必须实现你自己的 UserGroupCallback 类......像这样：

import java.util.ArrayList;
import java.util.List;

import javax.enterprise.inject.Alternative;

import org.kie.internal.task.api.UserGroupCallback;


@Alternative
public class MyUserGroupCallback implements UserGroupCallback {

    public boolean existsGroup(String groupId) {
        return true;
    }

    public boolean existsUser(String userId) {
        return true;
    }

    public List<String> getGroupsForUser(String userId, List<String> groupIds, List<String> allExistingGroupIds) {
        List<String> l = new ArrayList<String>();
        return l;
    }

}

然后提供您的实现的生产者：

import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.inject.Produces;
import javax.inject.Inject;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import javax.persistence.PersistenceUnit;

import org.jbpm.runtime.manager.impl.RuntimeEnvironmentBuilder;
import org.jbpm.runtime.manager.impl.cdi.InjectableRegisterableItemsFactory;
import org.kie.api.io.ResourceType;
import org.kie.internal.io.ResourceFactory;
import org.kie.internal.runtime.manager.RuntimeEnvironment;
import org.kie.internal.runtime.manager.cdi.qualifier.PerProcessInstance;
import org.kie.internal.runtime.manager.cdi.qualifier.PerRequest;
import org.kie.internal.runtime.manager.cdi.qualifier.Singleton;
import org.kie.internal.task.api.UserGroupCallback;

@ApplicationScoped
public class SimpleProcessRuntimeProducer {
    @SuppressWarnings("cdi-ambiguous-dependency")
    @Inject
    private InjectableRegisterableItemsFactory factory;

    @Inject
    private UserGroupCallback usergroupCallback;

    @Produces
    public UserGroupCallback produceUserGroupCallback() {
        return usergroupCallback;
    }

    @PersistenceUnit(unitName = "unitname")
    private EntityManagerFactory emf;

    @Produces
    public EntityManagerFactory produceEntityManagerFactory() {
        if (this.emf == null) {
            this.emf = Persistence
                    .createEntityManagerFactory("unitname");
        }
        return this.emf;
    }

    @Produces
    @Singleton
    @PerProcessInstance
    @PerRequest
    public RuntimeEnvironment produceEnvironment(EntityManagerFactory emf) {

        RuntimeEnvironment environment = RuntimeEnvironmentBuilder
                .getDefault()
                .entityManagerFactory(emf)
                .userGroupCallback(usergroupCallback)
                .registerableItemsFactory(factory)
                .addAsset(ResourceFactory.newClassPathResource("process.bpmn"),ResourceType.BPMN2)
                .get();       
        return environment;
    }
}

希望这可以帮助

你的类路径中有 jbpm-human-task-core 吗？（在战争内部还是在应用程序服务器库中？）
