Answer
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" %>
