You are getting a file from a specific servlet. Thus you do not use JSF to download the file. For the popup generation itself, what you can do is embed all the work of writing the little popup generating javascript and rendering the link button to a custom JSF component. This way you could write this in your .jsp <mylibrary:waitDownload url="/path/to/csv/servlet?get=myreport" popup="/path/to/pleasewait.html" ><h:outputText value="get the File!"/></mylibrary:waitDownload> If you can afford a dependency to tomahawk project, you can even serve the content of the popup as a html fixed in your .jar ressource an simplify your tag like this :) (using addResource and AddResourceFactory) <mylibrary:waitDownload url="/path/to/csv/servlet?get=myreport" /><h:outputText value="get the File!"/></mylibrary:waitDownload> Of course, creating this custom component is just a matter of reusing a bit of html code in a constant way eveyrwhere. It's not very difficult but can be seen as too much work to generalize 2 lines of html. You can achieve the same with subview to include a small portion of form, or with facelets that is using templates (but then you must be able to abandon use of JSP for you faces).
