Plain Tomcat + Quartz + Mail work together?
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:
@Name("coollectScheduler")
@AutoCreate
@Install(true)
public class CoollectScheduler extends EntityController {
/**

private static final long serialVersionUID = 1633034787217471953L;
private static final String WELCOME_MAIL_TEMPLATE = "/registration/welcome-email.xhtml";
@Asynchronous
@Transactional(TransactionPropagationType.REQUIRED)
public QuartzTriggerHandle scheduleWelcomeEmail(@Expiration
Date when, @IntervalDuration
Long interval, int numberOfRetries, User user) {
try {
user = getEntityManager().find(User.class, user.getId());
Contexts.getEventContext().set("newUser", user);
Contexts.getEventContext().set("numberOfRetries", numberOfRetries);
info("Trying #{newUser.welcomeEmailRetries + 1} of #{numberOfRetries} to send welcome email for the new user: #{newUser.name}");
render(WELCOME_MAIL_TEMPLATE);
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;
}
public static CoollectScheduler instance() {
return (CoollectScheduler) Component
.getInstance(CoollectScheduler.class);
}
}

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