How to start a process out of a xhtml file

[coolex]

Hello!

I want to start one of my processes without using a POJO and the @CreateProcess annotation but simply directly in my xhtml files.
Is it possible? How can I do this?

Thanks.

You can do this in pages.xml (but not directly from xhtml as this would be a confusion of concerns).

Ok, so it is not possible to start processes from a xhtml file? Or do you want to say that it does not make sense to do this?

The former follows directly from the latter (i.e. yes to both questions).

Aha, cool.
I'm just trying to find out the right way to manage my processes.
So, the best way is to create something like manager classes that starts, stops etc. my processes?

Pete answered your question.  You need to add the metadata/code into either pages.xml or components.xml depending on exactly when and what you're trying to do.

For example, I kick off the Quartz timer service after Seam starts up in components.xml:

   <event type="org.jboss.seam.postInitialization">  
        <action execute="#{controller.scheduleTimer}"/>
   </event>

Here's an example in pages.xml:

<pages>
   <page view-id="/hello.xhtml" action="#{helloWorld.sayHello}"/>
</pages>

The sayHello method will fire prior to the rendering of hello.xhtml.

Thanks guys.
My problem is that I'm new to SEAM. I have some books about seam. None of these books describe the way for managing the process like you've done above with page.xml. The books desribe a way by using POJOS.
What about using POJOS for process managing?

[coolex]

Just to make clear!
In the end I still need a POJO class for managing the process? Correct?
So the pages.xml uses a seam component (e.g. POJO class) to trigger something (process start).

Please correct me, if I'm wrong.
Thank you.

Correct

Cool! Many, many thanks. That helped me a lot!

I'm pretty sure the action handler component can be a EJB3 (SFSB or SLSB), if you consider that a POJO or not....
