copied!<p>I have a standalone job in Play 2.0.4 that I want to run on Heroku as described in <a href="https://github.com/jamesward/play2-scheduled-job-demo" rel="nofollow">https://github.com/jamesward/play2-scheduled-job-demo</a> I start the application just like in the samples:</p> <pre><code>public class QueueWorker { public static void main(String[] args) { Application application = new Application(new File(args[0]), QueueWorker.class.getClassLoader(), null, Mode.Dev()); Play.start(application); } } </code></pre> <p>But now, judging from the logs, Play connects to the database <em>twice</em> for some reason and EhCache fails the second time because it the name is already registered:</p> <pre><code>[[37minfo[0m] play - database [default] connected at jdbc:mysql://localhost/myproject?characterEncoding=UTF-8 [[37minfo[0m] play - database [default] connected at jdbc:mysql://localhost/myproject?characterEncoding=UTF-8 Exception in thread "main" net.sf.ehcache.ObjectExistsException: Cache play already exists at net.sf.ehcache.CacheManager.addCache(CacheManager.java:990) at play.api.cache.EhCachePlugin.x$3(Cache.scala:111) at play.api.cache.EhCachePlugin.cache(Cache.scala:109) at play.api.cache.EhCachePlugin.onStart(Cache.scala:127) at play.api.Play$$anonfun$start$1.apply(Play.scala:60) at play.api.Play$$anonfun$start$1.apply(Play.scala:60) at scala.collection.LinearSeqOptimized$class.foreach(LinearSeqOptimized.scala:59) at scala.collection.immutable.List.foreach(List.scala:45) at play.api.Play$.start(Play.scala:60) at play.api.Play.start(Play.scala) at jobs.QueueWorker.main(QueueWorker.java:32) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:120) </code></pre> <p>Interestingly this does not happen when I start the project with the "play run" command. Has anybody got a hint for me what this could be, or how I can debug where it's coming from?</p>
