Its hard to know what causes that. What is #{fileSystemManager}? where is it in
your deployed archive?

Hi Pete,
As this may be true, I'm still having troubles with UseJBossWebLoader=false and
JSF, eg when using RichFaces' Tree and adviseNodeOpened, throwing this
exception:

useJBossWebLoader is a hack to force everything onto the same classloader.
Why do you need it? The main reason was RichFaces but that now has split out an
API.

Yes. Be more careful about how you package your classes and don't put anything
which has dependencies in your EAR class loader, but instead on the web
classloader. Facelets functions can help a lot here.

So, to sumamrise the problem as I understand it:
* the FaceletsRenderer calls out to facelets to render the page (making no
alteration to the classloader used)
* Normally the classloader used is the WebappClassLoader (it is in the examples
always afaics) HOWEVER sometimes it ends up being the

* If you place everything in the ear myfaces blows up when rendering email

Brad, I've managed to replicate your problem doing this:
Thread.currentThread().setContextClassLoader(facesContext.getClass().getClassLoader());
inside FaceletsRenderer.render() (in the mail example facesContext is using the

I'll try to find some time this weekend to create something similar - it isn't
going to be easy. In each method call, there is typically some persistence
work, some jBPM work, followed by an attempt to send the email. It will be
tricky to provide a sample that does all that
Thanks,
Brad
Just to check, you're calling Renderer.instance().render(template) from a
method that has been called directly from JSF not via a JBPM action (or some
other indirect method e.g. Events) - i.e. the render is by the method called
from JSF or by a method it calls etc.
I know there are issues
sample Render calls...
This method is in a SFSB - user clicks a link in UI: (this one works!)
| public String dsaProvision() {
|
| TaskInstance task = jbpmContext.getTaskInstance(taskId.longValue());
|
| // Update the decision

I have more data - I hacked Facelets 1.1.2 to spit out some ClassLoader info.
What I found is that in one case, when calling Renderer.render(myTemplate), the
Classloader is the EAR's classloader.
In the other case, the classloader is the war's classloader.
not working - ear's classloader

This is very useful information :) I'm hoping to work on this at some point
this weekend.

One last bit of info...
A colleague of mine suggested putting the taglibs (seam-email, seam-ui,

weblogic in the past. I tried this, now email is working!

1.) put the seam-mail.jar and dependencies in the .war as you have done in the

Reviewing the .ear created by your seam-email example, I'm
I agree its classloading related. As I said, I can take a look, but i'm not

So, this is how I lay it out:
