Try this

Include the below jar as dependency [in WEB-INF/lib]

 struts-taglib.jar [any version, eg: struts-taglib-1.3.10.jar]

In JSP page :

<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>

How this works: The tag library descriptor [tld] information are defined inside the “struts-taglib.jar\META-INF\tld”

You can have a look at the answer mentioned in this SO post. I have a running example there No getter method for property... error

So either you can have the jar file as dependency or add the tag library descriptors inside your WEB-INF, and configure in web.xml

web.xml

<taglib>
     <taglib-uri>
      http://struts.apache.org/tags-bean
     </taglib-uri>
     <taglib-location>
      /WEB-INF/struts-bean.tld
     </taglib-location>
</taglib>
<taglib>
     <taglib-uri>
      http://struts.apache.org/tags-html
     </taglib-uri>
     <taglib-location>
      /WEB-INF/struts-html.tld
     </taglib-location>
</taglib>
<taglib>
     <taglib-uri>
      http://struts.apache.org/tags-logic
     </taglib-uri>
     <taglib-location>
      /WEB-INF/struts-logic.tld
     </taglib-location>
</taglib>

There is a mapping between what you configure here and the taglib you define in jsp page. The @taglib uri in the jsp page have to match with <taglib-uri> defined in web.xml

<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>

Simply you have to check Add Struts TLDs option while creating project.
As shown below in a screen-shot.

Add Struts TLDs: Lets you generate tag library descriptors for the Struts tag libraries. A tag library descriptor is an XML document which contains additional information about the entire tag library as well as each individual tag. In general this is not necessary, because you can refer to on-line URIs rather than local TLD files.
