I am getting the following exception in the log due to which the jobs are never get executed. It works fine in Jboss 4.2.  We recently migrated to Jboss 7 and all naming contexts are by default readonly in Jboss 7.

The source of the configuration was classpath.

The diskStore path for this CacheManager will be set to C:\Users\663401\AppData\Local\Temp\\ehcache_auto_created_1392114395874.

To avoid this warning consider using the CacheManager factory methods to create a singleton CacheManager or specifying a separate ehcache configuration (ehcache.xml) for each CacheManager instance.
