use Seam to respond with bytes (not XML) ?

codelion Mar 22, 2007 3:14 PM

Sure, I could do it with a Servlet. But then I'd have to figure out how to do everything else from a servlet that I already know how to do with .seam, .xhtml, .page.xml, security, exceptions, etc.

I have a byte array in the property of a component. Obviously accessible from within an action.

How do I make a response the return the bytes (with a MIME type of my choice)?

I've done it from a servlet before. But how from an action? Correctly?

Unfortunately, facelets doesn't allow returning binary data. Everything in Seam that returns binary data uses either a servlet or a phase listener to return the results. This is definitely something I'd like to see fixed in facelets so that we can do this.

Take a look at http://wiki.jboss.org/wiki/Wiki.jsp?page=SeamResourceLoader for how to do this from an action method.

Are you sure that page is current? What is in CVS now doesn't work anything like that. Am I missing something?

I have done it like in this post: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=103039
But the wiki page is quite pretty. So i will give it a try.
Peter, any chance that we get the Resource class into seam?

Norman, I think the approach is still valid - it's sort of an orthogonal approach to using a AbstractResource. I'll review it properly when I get a chance
