手工同步配置信息（sync命令），应用重新发布还是报错。页面报错信息：

Error 500: org.springframework.beans.factory.BeanCreationException:

Error creating bean with name 'dataSource' defined in ServletContext resource [/WEB-INF/configuration/coreContext.xml]:

Invocation of init method failed; nested exception is com.ibm.websphere.naming.CannotInstantiateObjectException:
