我使用primefaces框架来实现一个懒惰的数据表。 我导入了包：
import org.primefaces.model.LazyDataModel;
在我的EventViewer ManagedBean类中。 我将primefaces-6.1.jar放在WEB-INF / lib文件夹中。
在JBoss AS上部署项目后，在加载页面时，我得到以下异常：
2017-07-25 18:12:13,817 ERROR [javax.enterprise.resource.webcontainer.jsf.managedbean] JSF will be unable to create managed bean eventViewer when it is requested. The following problems where found:

这是主要错误：
- Bean or property class com.imnet.oam.fe.event.EventViewer for managed bean eventViewer cannot be loaded due to a missing dependency: org/primefaces/model/LazyDataModel.
我该如何解决？
