Is it possible to create any dashboard outside of Jasper BI server which can host reports created using iReports designer ?
It depends on what you want to do.
Where will you display your dashboard ?
Notice that a dashboard is simply several reports in one screen.
You can use web services to access the reports and display them in your web application. There is a folder "java-webapp-sample" in jasperserver installation directory.
I hope this helps
Thanks, but does that mean Jasper BI repository is required ? Can't I have just .jasper report developed from iReports stored in some file system and can be used to create some HTML5 dashboard ?
Jaspersoft Dashboard you can create from jaspersoft environment only it is a combination of multiple reports but you can create anlytical dashboard that you want. There are various widgets, chartspro and HTML5 charts available in iReport designer so you can create a small reports of each specific chart and design a good dashboard.
Dashboard directely through iReport not Possible.
I am planning to use HTML using GWT toolkit or equivalent running on web container.
Can this be done ? How to access these reports from there ?
