OFBiz报错处理-找不到实体learn报错

在 learn模块的三个菜单页面下方和webtools实体引擎页面下方出现报错信息

:ERROR MESSAGE:
org.apache.ofbiz.widget.renderer.ScreenRenderException: Error rendering screen 
[component://learn/widget/LearnScreens.xml#FindLearn]: 
org.apache.ofbiz.entity.transaction.GenericTransactionException:
 Roll back error, could not commit transaction, was rolled back instead because of: 
Service [prepareFind] threw an unexpected exception/errororg.apache.ofbiz.service
.GenericServiceException: 
Service [prepareFind] target threw an unexpected exception (null) (Service [prepareFind]
 target threw an unexpected exception (null)) (Roll back error, could not commit transaction,
 was rolled back instead because of: 
Service [prepareFind] threw an unexpected exception/errororg.apache.ofbiz.service
.GenericServiceException: Service [prepareFind] target threw an unexpected exception (null) 
(Service [prepareFind] target threw an unexpected exception (null)))

   原因：这个错是因为entitymodel.xml文件出错，中间缺少了entity-name属性 。

而在控制台出现
