The taglib element in web.xml is invalid because a taglib-uri element is a duplicate of the other taglib element. (J2EE application = aa....aa, context root = bb....bb, taglib-uri element in the invalid taglib element = cc....cc, taglib-location element in the invalid taglib element = dd....dd)

aa....aa: The J2EE application name in the case of the J2EE server mode, and a null character string in the case of the servlet engine mode, or the cjjspc command
bb....bb: The context root name in the case of the J2EE server mode or the servlet engine mode, and a null character string in the case of the cjjspc command
cc....cc: Contents of the <taglib-uri> element present in the invalid <taglib> element
dd....dd: Contents of the <taglib-location> element present in the invalid <taglib> element

Description

The contents of the <taglib> element specified in web.xml will become invalid because another <taglib> element with the same <taglib-uri> element is specified.

Action

Specify a value in the <taglib-uri> element defined in web.xml so that it is not the same as the <taglib-uri> element specified in another <taglib> element.

Correct the error location, and then update the Web application.

In the case of the J2EE server mode
