How to reload a jasper report repeatedly within every one minute

[prabuddha.kulatunga]

I use a jasper report as my dashboard on Jasper Server 6.4.2 version.on that report, I have to display current time with live updates without reloading the report manually. I tried to schedule the report and set as output options as Overwrite Files and it's not worked.

Basically,I want to reload a report when it already opened and displayed withing every given time period repeatedly until I close the report. How can I do this?

If you are using Java Then use multithreading while file output to load every time period given by you

No. I use JasperSoft Studio and Jasper Server only.

Try this... 

Once you open the Report with parameter selections, the REST URL will be populated with all the parameters that it needs. 

Use some kind of browser refresh plugins to refresh the browser page

personally I use chrome

Have you tried setting "Refresh Settings" - "Auto-refresh dashlet contents"

Found a way by myself.

Go to ViewReport.jsp on jasper server installation files.

Then add below code for it.(Actually we use java script to do this.)

 <script type="text/javascript">
     var url = window.location.href; //take current tab url
     var dash = 'http://localhost:8080/jasperserver/flow.html?_flowId=viewReportFlow&_flowId=viewReportFlow&ParentFolderUri=%2FMy_Reports&reportUnit=%2FMy_Reports%2FDashboard_Report_Original__2_&standAlone=true';
     
     if(url == dash ){
        setTimeout(function(){
            window.location.reload(1);
        }, 5000);
     }
</script>

url is the current display report url.

dash is the url that we want to refresh. otherwise all the reports will be refresh withn every 5seconds.

5000 is time gap want to refresh.

restart the jasper server.

that's it..
