    Producer Method and java.io.NotSerializableException

    Steve Hostettler Newbie



      There is something that I can really understand in my project. I get a java.io.NotSerializableException exception when Tomcat shuts down.



      WARNING: Cannot serialize session attribute org.jboss.weld.context.ConversationContext.1#org.jboss.weld.bean-flat-ManagedBean-class ch.demo.web.ManageStudentRegistration for session 91DA3D803BD3BC86DCF7C5FF6BF6F942
      java.io.NotSerializableException: java.util.logging.Logger
                at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1164)
                at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1518)
                at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:{1483)



      My managed bean has a logger field which is transient:



      public class ManageStudentRegistration implements Serializable {
       private static final long serialVersionUID = 2123342218792192804L; 
       private transient Logger mLogger;




      The producer for the logger looks like:



      public class LoggerProducer  implements Serializable {
          private static final long serialVersionUID = -7352371086416154400L;
          public Logger getLogger(final InjectionPoint injectionPoint) {
              return LoggerFactory.getLogger(injectionPoint.getBean().getBeanClass());




      I do not understand what field it tries to serializable as the mLogger is transient.


      In debug mode I get the following output from ObjectOutputStream.writeObject:


      Bean: Producer Method [Logger] with qualifiers [@Any @Default] declared as [[method] @Produces public ch.demo.helpers.LoggerProducer.getLogger(InjectionPoint)]; Instance: org.slf4j.impl.JDK14LoggerAdapter(ch.demo.web.ManageStudentRegistration); CreationalContext: org.jboss.weld.context.CreationalContextImpl@17e34309



      Obviously the problem is in the producer not in the member field mLogger.


      Did I miss something obvious?


      Many thanks in advance for your help
