Cant send emails out of my stateless component

[rufs]

Hi, i want to send reports from database as emails. I created a component EmailHandler that sends the mails..

When i invoke the methods from a button out of a page

   <h:commandButton id="mailExample" value="send" action="#{emailHandler.sendEmail}"/>
   <h:commandButton id="mailExampleasync" value="sendasync" action="#{emailHandler.sendEmailAsync}"/>
           

everything works great and the emails are sent successfully.....


but when i inject this EmailHandler into my Component that generates the reports, i always get the following exception

any ideas??

If you look at this blog it was very helpful for me:

http://gariboldi.blogspot.com/2007/12/seam-and-asynchronou.html

Your problem is probably that you havent set the component in the asynchronous scope. You must remember that you cannot retrieve the seam components the normal way when running asychronous.
So you will need to set it manually in the asynch method:

Contexts.getConversationContext().set("account", account);

Also remember to update components.xml

<async:quartz-dispatcher/>

Did you find a solution to this?

I'm getting this exact same exception, only it's when I call my email handler from a webservice, implemented as a SLSB. It kindof make sense that there is no FacesContext available since it's a non-faces request.

I've stepped into Render.render, and into RendererRequest.init() where it calls RendererFacesContextFactory.instance() which looks in the Application context for an instance of itself, which fails.

I can't find where the Application context is primed with an instance of RendererFacesContextFactory however, and am stuck...

[jamathison]

Actually, I see that the RendererFacesContextFactory is indeed being instantiated, and its' @Create method is called, which in turn calls javax.faces.FactoryFinder.getFactory which throws an IllegalStateException...  which I would've seen if I'd looked at the stack trace more carefully...
