Hi Massimiliano, it works thank you! However there are 2 things i do not like:
1) My PDF File is renamed to the same as my Controller function Name plus a number and *without the Extension .pdf*. Example:* printlanguages+cd123452* 2) After the *"return response.stream()"* my *submit button* that started the Output remains pressed until i refresh the url-page manually. Is there a way to Redirect to the URL after the pdf file was displayed? Do you or does anybody else have a solution for this? Am Dienstag, 3.
