Hi Hans, What Matthias describes below is where you have a JSF page, and you want a button labelled "generate report" or similar that creates some kind of PDF document then serves it up to the user's browser. But that PDF isn't "a picture of the current page", it's a PDF generated using data pulled from a database or something like that. If that's really what you are after then FOP is a good tool for that; your java code creates some xml using the FO schema, then feeds it to the FOP library. Nothing to do with JSF though.
There is no way to "generate a pdf that looks like my html screen" from java code which I believe is what you want to do. Some browsers provide a "print page" option, and some operating systems provide a "print to PDF" option in the print dialog so that's one way of creating a PDF that contains the current page but it's manual. The FOP project is here: http://xmlgraphics.apache.org/fop/ Regards, Simon On Tue, 2006-01-17 at 09:58 +0100, Hansjörg Meuschel wrote: > Hi Matthias, > > thanks for your help... a friend of mine also recommended FOP in > between.
