我已经在 J​​SP 中使用此代码来显示表格，但在显示此 JSP 页面之前，我得到了java.lang.ClassNotFoundException: org.displaytag.tags.TableTagExtraInfo异常，并且ERROR ServletException in '/pages/appEntry/baseLife/HUF.jsp': org.displaytag.tags.TableTagExtraInfo org.apache.jasper.JasperException: Failed to load or instantiate TagExtraInfo class: org.displaytag.tags.TableTagExtraInfo 我已经导入了这个错误，displaytag-1.2.jar但我仍然遇到了错误。
