Integration as a portlet in uPortal
This servlet can be easily integrate in uPortal into an iframe.
User interface are built on top of Twitter Bootstrap 3.1 and therefore are responsive.
This servlet integrates a JavaScript snippet made by Pascal Rigaux to resize an iframe depending on its content. If you want this feature to work you will need to include a JavaScript snippet in the portal too (view Github repo : https://github.com/EsupPortail/iframe-autoheight-using-postMessage).
