Seam 2.2 duvidas com Exceptions

Front-end
#1

Ola pessoal, existe alguma maneira de capturar as exeptions geradas pela aplicacao usando seam 2.2 e enviar estas exceptions “descricao” por email?

#2

Resolvi assim:
Um componente seam para interceptar as exception

package br.com.inferno.mbean;

import java.io.Serializable;

import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Observer;
import org.jboss.seam.annotations.Scope;
import org.jboss.seam.contexts.Contexts;
import org.jboss.seam.exception.Exceptions;
import org.jboss.seam.faces.FacesMessages;
import org.jboss.seam.faces.Renderer;

@SuppressWarnings("serial")
@Name("error")
@Scope(ScopeType.APPLICATION)
public class ErrorAction extends Exceptions implements Serializable {

	@In
	private Renderer renderer;

	@In(value = "org.jboss.seam.handledException", required = false)
	public Exception exception;

	@In
	FacesMessages facesMessages;
	
	
	@Observer(value = "org.jboss.seam.exceptionHandled")
	public void sendMail() {
		sendErrorMail(exception, "Exception no ambiente de produção.");
		facesMessages.add("Ocorreram erros ao executar a operação.");
	}

	public void sendErrorMail(Throwable throwable, String message) {
		StringBuffer err = new StringBuffer();
		if (throwable != null) {
			err.append(throwable.getLocalizedMessage()).append("\n");
			err.append(throwable.getMessage()).append("\n");
			for (StackTraceElement elem : throwable.getStackTrace()) {
				err.append(elem.getFileName()).append(":")
						.append(elem.getLineNumber()).append(":")
						.append(elem.getClassName()).append(":")
						.append(elem.getMethodName()).append("\n");
			}
		}
		Contexts.getEventContext().set("subject", message);
		Contexts.getEventContext().set("body", err.toString());
		Contexts.getEventContext().set("to", "leandrog@inferno.com.br");			
		renderer.render("/acaoMail.xhtml");

	}

}
