I need to display my reports in my web application

Hello ,

Thank you for your response , I still have the issue
Could you please see in details what i did :
- in my java web project and under the folder WEB-INF i paste the 7 folders : assets, assist,classes,embed,lib,plugins and reportls
-then in html file i added a section :
<section>
    <iframe src="http://localhost:8080/faurecia-monitoring/decision/view/form?viewlet=MDM%2BDEV%252FWFs%2Bstatus%2Brates.frm" frameborder="0" style="width: 100%; height: 800px;">
    </iframe>
</section>
But When i start the server it's not working.
Is tehre a missing step and what could be my mistake.
