<div dir="ltr" style="text-align: justify;" trbidi="on">In this section, we are going to describe the include tag. The include tag is a generic tag that is used to include a servlet&#8217;s output (result of servlet or a JSP page) to the current page. </p>
<p> The struts include tag is very similar to the jsp include tag and it is rarely used. We have seen how to include the output of a struts action into a jsp using the <;s:action>; tags. The <;s:include>; tag is slightly different. It allows you to include the output of a jsp, servlet or any other resource (something other than a struts action) into a jsp. Behind the scenes it is exactly similar to the <;jsp:include>;, but it allows you to pass parameters to the included file and it is also part of Struts framework.</p>
<p> Add the following code snippet into the <i><b>struts.xml </b></i>file.</p>
