Если вы работаете над веб-приложением и определяете taglibs в файле web.xml, то вы можете столкнуться с этим исключением. Трассировка исключения в консоли сервера выглядит следующим образом при запуске сервера.

Решение
Вам просто нужно подтвердить разрешенные теги с помощью файла DTD подтверждения web.xml. Например, версия = «2.5″ совместимый web.xml требует, чтобы вы определили библиотеки тегов следующим образом.
<jsp-config><taglib><taglib-uri>/tags/struts-bean</taglib-uri><taglib-location>/WEB-INF/struts-bean.tld</taglib-location></taglib><taglib><taglib-uri>/tags/struts-html</taglib-uri><taglib-location>/WEB-INF/struts-html.tld</taglib-location></taglib><taglib><taglib-uri>/tags/struts-logic</taglib-uri><taglib-location>/WEB-INF/struts-logic.tld</taglib-location></taglib><taglib><taglib-uri>/tags/struts-nested</taglib-uri><taglib-location>/WEB-INF/struts-nested.tld</taglib-location></taglib></jsp-config>
