async:quartz-dispatcher + serializied fields in an entity = java.lang.ClassNotFoundException: No ClassLoaders found

    Details

    • Type: Bug
    • Status: Closed (View Workflow)
    • Priority: Major
    • Resolution: Rejected
    • Affects Version/s: 2.0.0.GA, 2.0.1.CR1
    • Fix Version/s: 2.0.2.CR1
    • Component/s: Async
    • Labels:
      None
    • Environment:

      JBoss AS 4.2.2.GA, Seam 2.0.1.CR1 and 2.0.0.GA

      Description

      When an asynchronous method is called, which reads entities from the DB which have serializable fields (with just an @Basic annotation), and the quartz dispatcher is used, a java.lang.ClassNotFoundException is thrown, when trying to read the entities.

      I attach a demo app (it is built using seam-gen 2.0.1.cr1, and has the lib directory removed).
      The application has the following classes:

      • SimpleEntity - an entity which just one property of class: SimpleSerializable - this is the serializable property
      • AsyncService / AsyncServiceImpl - this is the stateless bean that has the asynchronous method. The method simple reads all SimpleEntities from the database.

      To run the example, deploy it, open in the browser http://localhost:8080/serialization_test and click "Add new simple entity".
      This invokes an action, which persists a new SimpleEntity to the DB and invokes the asynchronous method.

      An exception then appears in the log, coming from the asynchronously called method:
      09:50:25,745 ERROR [ErrorLogger] Job (DEFAULT.614f04c4:117680a919e:-7ffe threw an exception.
