Re: Sending a file to ServletContext Response failure
Posted by Johnny Gonzalez <jo...@yahoo.es>.
Hello Matthias,
I submitted the change to the wiki, but it still

Thanks a lot,
Johnny

Re: Sending a file to ServletContext Response failure
Posted by Matthias Wessendorf <ma...@apache.org>.
easy to create a password (use the login link)
added to
"JSF and MyFaces in Praxis: Specialized Trails"
and create a subtitle like "sending files (like PDF) to the browser"
something like that.

Hello Matthias,
I'd like to, but I have no idea where to put it on the
wiki, Where do you recommend me to post it?
Do I need a password for doing so?
Thanks a lot,
Johnny
