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. org.quartz.SchedulerException: Job threw an unhandled exception.

async:quartz-dispatcher + serializied fields in an entity = java.lang.ClassNotFoundException: No ClassLoaders found ------------------------------------------------------------------------------------------------------------------- Key: JBSEAM-2484 URL: http://jira.jboss.com/jira/browse/JBSEAM-2484 Project: JBoss Seam Issue Type: Bug Components: Async Affects Versions: 2.0.1.CR1, 2.0.0.GA Environment: JBoss AS 4.2.2.GA, Seam 2.0.1.CR1 and 2.0.0.GA Reporter: Adam Warski Assigned To: Norman Richards Fix For: 2.0.2.GA Attachments: serialization_test.tar.gz, serialization_test.tar.gz 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. org.quartz.SchedulerException: Job threw an unhandled exception.
