我编写了一个示例Portlet和一些在portlet的view.jsp文件中调用的Tag文件。实际上，我已经编写了一个下面的代码，用于在view.jsp
中调用Tag a Tag文件<%@taglib tagdir="/WEB-INF/tags/base" prefix="samfadBase"%>
然后，我在view.jsp文件中使用了以下代码。
<samfadBase:Initialize moduleName="ReportDefinition"></samfadBase:Initialize>
当我部署我的portlet时，会引发一个
的异常ERROR [http-nio-8080-exec-5][PortletRequestDispatcherImpl:261] org.apache.jasper.JasperException: PWC6033: Error in Javac compilation for JSP__PWC6197: An error occurred at line: 11 in the jsp file: /html/reportViewer/reportDefinition/view.jsp_PWC6199: Generated servlet error:_package org.apache.jsp.tag.web.base does not exist__PWC6197: An error occurred at line: 11 in the jsp file: /html/reportViewer/reportDefinition/view.jsp_PWC6199: Generated servlet error:_package org.apache.jsp.tag.web.base does not exist__ [Sanitized]
