Use MyFaces for file download
Hi,
I am trying to write a Java web app using JSF.
I have a page which takes some info from user and it has a submit button.
If the validation of the info entered by user is correct, the web app
will send down a file.
All the example I look at has navigation rule while navigate from one
jsp to another. How can I send down a file instead of loading another
jsp?
Thank you.

ying,
yes it means <h:commandButton action="#{mybean.action}" value="Go!" />
in java:
public String action()
{
...
}

yeah,
I suggest finishing that tutorial first, before doing a productive app.
The myfaces wiki has also good resources or links to them
jsfcentral.com might be interesting as well
Try to buy "The complete reference JavaServer Faces"
by Ed Burns (member of the guys that *create* JSF).

Should I do something like this:
<h:commandButton
value="#{bundle.Submit}"
action="#{cashier.submit}" />

Matthias,
Thanks for your link.
Can you please help me understand what it means by 'You have to bind
an action in the JSP to a method in your backing bean.'?
Is there an example for that?
Thanks again.

Re: Use MyFaces for file download
Posted by dani <da...@swisscom.com>.
Hi
I have a follow up question on this topic. I am also trying to download a
file (picture) in my aplication. I followed the instrcution on the Wiki page
but I have a content type problem. Eventhough I specify my content type to
"image/jpg" on the outputstrean, on the webpage I have still "text/html".
Any suggestions?
Thanks
Daniel
