For integrating your jasper report into the web application with struts2-jasper-plugin,

you need to do the following things

struts.xml

<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
 <constant name="struts.devMode" value="true" />
 <constant name="struts.action.excludePattern" value="/servlets/.*" />
 <package name="default " namespace="/"
  extends="struts-default,json-default,jasperreport-default">
  <result-types>
   <result-type name="jasper" class="org.apache.struts2.views.jasperreports.JasperReportsResult"/>
  </result-types>
  
  <action name="myJasperTest" class="com.jasper.admin.action.JasperAction">
   <result name="success" type="jasper">
    <param name="location">/WEB-INF/classes/jasper/our_compiled_template.jasper</param>
             <param name="dataSource">myList</param>
             <param name="format">HTML</param>
             <param name="imageServletUrl">/servlets/image?image=</param>
         </result>
     </action>
    </package>
</struts>

in the above struts.xml observe orange color line, these lines are very important for struts-jasper-plugin

JasperAction.java

        String dir = request.getRealPath("/");

        // Normally we would provide a pre-compiled .jrxml file
        // or check to make sure we don't compile on every request.
        try {
            JasperCompileManager.compileReportToFile(dir+ "/WEB-INF/classes/jasper/our_jasper_template.jrxml", dir+ "/WEB-INF/classes/jasper/our_compiled_template.jasper");

    }
