    JBoss AS6 and Quartz 1.8.4 Not Finding Properties

    Larry Wilson Newbie

      We're trying to upgrade from JBoss 5 to JBoss 6, and step up to Quartz 1.8.4 in the process. I have been completely unsuccessful in getting JBoss 6 to load my quartz.properties file and am looking for advice from someone who has succeeded at this, or someone who knows how this is supposed to happen.

       

      The files

      my-quartz.properties (scaled back for testing), which contains:

      org.quartz.scheduler.instanceName = QuartzScheduler

      org.quartz.scheduler.instanceId = AUTO

      org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool

      org.quartz.threadPool.threadCount = 5

      org.quartz.threadPool.threadPriority = 5

      org.quartz.jobStore.misfireThreshold = 60000

      org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

       

      properties-service.xml, which contains:

          <attribute name="Properties">

            org.quartz.properties=${jboss.server.config.url}my-quartz.properties

          </attribute>

       

      Actions Attempted

      I've tried placing the my-quartz.properties file in %JBOSS_HOME%/bin, %JBOSS_HOME%/server/default/conf, and %JBOSS_HOME%/server/default/deploy - with a failed load defaulting back to the quartz.properties in the quartz jar (see Results, Part 2).

       

      I ran across a thread yesterday about updating %JBOSS_HOME%/server/default/deply/properties-service.xml, which I'm including here.

       

      The Results, Part 1

      When updating properties-service.xml and restarting JBoss, it throws the following error:

      13:16:51,614 INFO  [[/QuartzTest]] QuartzInitializer: Quartz Scheduler failed to initialize: org.quartz.SchedulerException: Properties file: 'file:/Users/me/jboss-6.0.0.Final/server/default/conf/my-quartz.properties' could not be found.

       

      Yet if I run this from a command prompt, it displays the file contents just fine:

      less /Users/me/jboss-6.0.0.Final/server/default/conf/my-quartz.properties

      Note that is exactly the file JBoss says it cannot find.

       

      The file exists, it has the proper permissions, yet JBoss cannot find it. To confirm it's not a permissions issue I ran JBoss as root and received the same error.

       

      The Results, Part 2

      Before finding the properties-service.xml solution, I tried locating my-quartz.properties in the classpath (%JBOSS_HOME%/bin, %JBOSS_HOME%/server/default/conf, and %JBOSS_HOME%/server/default/deploy). When started, JBoss throws the following info message:

      13:32:55,896 INFO  [StdSchedulerFactory] Quartz scheduler 'DefaultQuartzScheduler' initialized from default resource file in Quartz package: 'quartz.properties'

       

      Again, it obviously cannot locate the file.

       

      Prologue

      I'm completely stumped. Nothing I have tried has been able to be loaded by JBoss. Anyone have any ideas?

       

      Thanks,

      Larry

          Can it find it if you place it in the classpath root inside your application?

            I've tried placing the file in the WEB-INF directory of the application, and the INFO message still says "initialized from default resource".

             

            And besides - that won't work if you have multiple applications on a server that use Quartz. How could they each have the quartz config? Correct?

              I have just successfully loaded the quartz.properties when it's placed inside my WEB-INF directory by adding the following (in bold) to web.xml:

               

                <servlet>

                  <servlet-name>QuartzInitializer</servlet-name>

                  <servlet-class>org.quartz.ee.servlet.QuartzInitializerServlet</servlet-class>  

                  <init-param>

                    <param-name>shutdown-on-unload</param-name>

                    <param-value>true</param-value>

                  </init-param>

                  <init-param

                    <param-name>start-scheduler-on-load</param-name> 

                    <param-value>true</param-value> 

                  </init-param

                  <init-param>

                    <param-name>config-file</param-name>

                    <param-value>my-app-quartz.properties</param-value>

                  </init-param>

                  <load-on-startup>1</load-on-startup>

                </servlet>

               

               

              Confirmed with log output:

              15:22:42,253 INFO  [StdSchedulerFactory] Quartz scheduler 'QuartzScheduler' initialized from the specified file : 'my-app-quartz.properties' from the class resource path.

               

              So, this is progress. But the question remains - is this a good practice since there will be more than one application running on the JBoss server that uses Quartz? Shouldn't this be a server-wide setting? And, how do you make that happen? Under JBoss 5, we just placed it in the bin directory of the server, along with all of the <appname>-jobs.xml files; worked like a champ - and maybe we violating rules and lucky.

                It does appear a bit overkill, yes. And no luck on the Quartz forums? One would think that someone over there would have run into this issue...

                  Have you tried to force-feed it something like /tmp/q.properties to see at which point the file:/ url appears?

                    ....

                     

                    The Results, Part 1

                    When updating properties-service.xml and restarting JBoss, it throws the following error:

                    13:16:51,614 INFO  [[/QuartzTest]] QuartzInitializer: Quartz Scheduler failed to initialize: org.quartz.SchedulerException: Properties file: 'file:/Users/me/jboss-6.0.0.Final/server/default/conf/my-quartz.properties' could not be found.

                     

                    Like I suspected the Quartz StdSchedulerFactory can't handle the "file:" protocol in the file "name":

                     

                     public void initialize(String filename) throws SchedulerException {
                      ...
                      InputStream is = null;
                                 Properties props = new Properties();
                    
                                 is = Thread.currentThread().getContextClassLoader().getResourceAsStream(filename);
                    
                                 try {
                                     if(is != null) {
                                         is = new BufferedInputStream(is);
                                         propSrc = "the specified file : '" + filename + "' from the class resource path.";
                                     } else {
                                         is = new BufferedInputStream(new FileInputStream(filename));
                                         propSrc = "the specified file : '" + filename + "'";
                                     }
                                     props.load(is);
                                 } catch (IOException ioe) {
                                     initException = new SchedulerException("Properties file: '"
                                             + filename + "' could not be read.", ioe);
                                     throw initException;
                                 }
                    ...
                    

                     

                    So change your properties-service.xml contents to (use the dir property instead of url property):

                     

                    <attribute name="Properties">
                          org.quartz.properties=${jboss.server.home.dir}/conf/my-quartz.properties
                        </attribute>

                      Fantastic catch - works like a champ! THANK YOU!
