SerializationException when attempting to activate a statefu

[redyz]

Hi,

I got the SerializationException problem when JBoss 4.0.4 tries to activate a stateful session bean that was passivated (and hence serialized to a file unser [JBOSS-DIR]/server/all/tmp/sessions directory). I am not using enum. The error is as follows:

Exception in thread "AWT-EventQueue-0" java.lang.RuntimeException: org.jboss.serial.exception.SerializationException: Could not create instance of org.hibernate.ejb.QueryImpl - org.hibernate.ejb.QueryImpl

Somehow the deserialization in JBoss is not working during activation??

btw my server.log looks like this:

hi redyz,

i did it,
the problem is that in statefull session bean i had define Query class object and this class is not a serializable.

you must define this class as transient or use it only method scope.....
my programm example

@Stateful
@Remote(CountFasade.class)
public class CountFasadeBean implements CountFasade {

 @PersistenceContext(unitName = "srvProvOracle")
 private EntityManager oracleManager;

 Query _query = null;

 public void addCount() throws Exception {
 try {
 _query = oracleManager.createNativeQuery("some query");
 } catch (Exception e) {
 e.printStackTrace();
 throw e;
 }
 }
}

must be like this :

@Stateful
@Remote(CountFasade.class)
public class CountFasadeBean implements CountFasade {

 @PersistenceContext(unitName = "srvProvOracle")
 private EntityManager oracleManager;

 @Transient
 Query _query = null;

 public void addCount() throws Exception {
 try {
 _query = oracleManager.createNativeQuery("some query");
 } catch (Exception e) {
 e.printStackTrace();
 throw e;
 }
 }
}

or like this :

@Stateful
@Remote(CountFasade.class)
public class CountFasadeBean implements CountFasade {

 @PersistenceContext(unitName = "srvProvOracle")
 private EntityManager oracleManager;

 public void addCount() throws Exception {
 try {
 Query _query = oracleManager.createNativeQuery("some query");
 } catch (Exception e) {
 e.printStackTrace();
 throw e;
 }
 }
}

good luck
