How to display image stored as BLOG with seam?

[hurzeler]

Hello there,

I am looking for a solution that allows me to display an image that is stored in a DB as BLOG using JSF and seam.

I had a look on the net and found a couple of solutions that us a servlet and write the outputstream to the HTTP resp. However how do you do that with seam?

Thanks for your help.

use facesContext.getExternalContext().getResponse()

How would my <h:graphicImage id="image" url="#{bean.????????}" /> look?

Hey Peter,

I looked at your solution at http://jroller.com/page/pmuir?entry=dynamicimagecomponent_for_jsf .

I just have one question: How does the header ?? of the my.tag.lib.xml look? Or it doesn't matter?

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE taglib PUBLIC "??" "??">


<tag-name>dynamicImage</tag-name>

<component-type>uk.co.splendid.jsf.DynamicImage</component-type>




Thanks Bernie

For the purposes of that post I was assuming you had your own facelets taglib set up. [1] describes how to set up facelets taglibs (the wiring section) as does the facelets reference manual [2].

Please NB if you aren't using facelets then my wiring won't work for you - you would need to write some JSP wiring (a .tld entry, a Tag class I think).
