[jboss-user] [JBoss Seam] - Plain Tomcat + Quartz + Mail work together?

[pettersonfp]

Hello,

  I've been trying to send an email inside a method annotated with @Asynchronous in plain tomcat using quartz.  The method is called properly and works fine, however, for some reason, the renderer cannot find the facelet template (xhtml).
  If I send the email in a normal method it works fine.
  After tracing the code I noticed that the problem occurs at the following code returning null:

  | package org.jboss.seam.util;
  | ...
  | public class Resources 
  | {
  | ...
  |    public static URL getResource(String resource, ServletContext servletContext) 
  |    {
  |       String stripped = resource.startsWith("/") ? 
  |             resource.substring(1) : resource;
  |    
  |       URL url  = null; 
  | 
  |       if (servletContext!=null)
  |       {
  |          try
  |          {
  |             url = servletContext.getResource(resource);
  |          }
  |          catch (Exception e) {}
  |       }
  |       
  |       if (url==null)
  |       {
  |         url = getResource(resource, stripped);
  |       }
  |       
  |       return url;
  |    }
  | ...
  | }
  | 
I think that when at tomcat the quartz threads are unable to find the resources but I don't understand why.

Following are the configurations, code and stack trace:

  | @AutoCreate
  | @Install(true)

  | 	try {
  | 	    user = getEntityManager().find(User.class, user.getId());
  | 	    Contexts.getEventContext().set("newUser", user);

  | 	    info("Trying #{newUser.welcomeEmailRetries + 1} of #{numberOfRetries} to send welcome email for the new user: #{newUser.name}");

  | 	    user.welcomeEmailSuccessfullySent();
  | 	    user.getQuartzHandle().cancel();
  | 	    info("Welcome email was successfully delivered to #{newUser.name} at #{newUser.email}.");
  | 	} catch (Exception e) {
  | 	    e.printStackTrace();
  | 	    user.incWelcomeEmailRetries();
  | 	    if (user.getWelcomeEmailRetries() >= numberOfRetries ) {
  | 		warn("Welcome email was not delivered to #{newUser.name} at #{newUser.email} and the system will not try again.");
  | 		try {
  | 		    user.getQuartzHandle().cancel();
  | 		} catch (SchedulerException swallow) {
  | 		    error(swallow.getLocalizedMessage());
  | 		}
  | 	    } 
  | 	    else {
  | 		    warn("Welcome email was not delivered to #{newUser.name} at #{newUser.email} due to: "
  | 			    + e.getLocalizedMessage()
  | 			    + ", the system will try again automatically.");
  | 	    }
  | 	}
  | 	getEntityManager().persist(user);
  | 	getEntityManager().flush();
  | 	return null;
  |     }
  |

  | 	return (CoollectScheduler) Component
  | 		.getInstance(CoollectScheduler.class);

What can I do to render an email inside an asynchronous method in plain tomcat?

Thanks in advance,
