Hi, I have a problem at created a portlet for the download file. When I set the response.setContentType('application/octect'); and response.setHeader('Content-disposition', 'attachment;filename=output.xml'); my portlet don't work. Is There a portlet the download a file??? Best regards.

Displaying a spinning wheel with Content Launch builder or any File Download functionality in Web Experience Factory (WEF) has always been tricky. Kirmes In Second Life Simulation. Once the user clicks on a link/button to download a file the user request moves server-side and if that operation takes too long then there is no way to let the user know that server is working on their request. The out-of-the box progress indicator that WEF provides is not designed to work in this scenario. The ideal solution in this case is to improve the performance of the file download service.

However we don’t live in a perfect world and hence there can be cases where the customer is aware of the slow performance of the file download service caused due to their back-end services and process which they cannot fix immediately. Instead the request to the development team is to show some kind of an indicator such as spinning wheel to the end user while the file download service completes its processing.

Once the JavaScript reads the updated cookie value as “Completed”, it hides the spinning wheel image.
