I need to display my reports in my web application

HI,ghofrane:

         If you want to deploy the report project to an existing web project, you can refer to this document：
         http://doc.fanruan.com/display/VHD/Embedded+Deployment

HI,ghofrane:

Based on your feedback, you need to confirm the following questions
1-Can the web project start successfully? This is a prerequisite
To detect whether the deployment is successful: restart Tomcat, open the browser, enter in the address
http:/ip:port/project name/decision, if you can successfully enter the page shown in the figure below, it means that the FineReport application integrates the Web application and deploys the Tomcat server successfully;


If you cannot access the decision platform by accessing http:/ip: port/project name/decision, it means that your project has not been successfully deployed.
You can copy tools.jar under %JAVA_HOME%/jdk/lib to the deployed server For details, refer to: Tools.jar-https://help.finereport.com/doc-view-2475.html introduced in server deployment.

2- After the server starts successfully, please check the storage location of the html page, the html file needs to be placed in the WebContent directory

3-Src in iframe, you can use / directly， without transcoding
<iframe src="http://localhost:8080/faurecia-monitoring/decision/view/form?viewlet=demo/Dashboard/Smart City.frm" frameborder="0" style="width: 100%; height: 800px ;">
</iframe>

The final effect is as follows
