    Plain Tomcat + Quartz + Mail work together?

    Petterson Paula Newbie

      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,
