✔ Problem mit SessionBean

Erfahrenes Mitglied
Hallo ihr lieben

Ich habe da mal ne Frage zu SessionBeans. Ich habe einige SessionBeans und musste festestellen, dass sie noch nicht so 100%ig ok sind.

Ich starte meine Application und alles t einwandfrei. Bin ich nun aber in einer Dialogmaske und warte dort ca 10 pder 20 minuten, dann bekomm ich einen "debug-Page" und er kann eine Variable nicht finden. Er sagt immer das er sie nicht lesen kann, aber es sind alle Methoden dafür vorhanden.

Ich habe auch schon etwas im Netzt gesucht und habe rausgefunden dass meine Beans wohl passiviert werden, damit der JBoss mehr Speicher hat.
Kann ich dagegen was tun? Ich möchte das meine Beans auf jeden Fall 30 min lang nicht passiviert werden oder auch garnicht wenn das möglich ist.

Kann mir da wer helfen? Bin etwas ratlos. :suspekt:
 
Hallo,

hast du zu deinem Problem noch etwas mehr Informationen, wie z.B. den Quellcode der Bean, den Quellcode, wo du auf die entsprechenden Methoden der Bean zugreifst bzw einen relevanten Ausschnitt aus dem Server-Log, wo der Fehler drin steht? Weil so ist das ganze eher Raten ins Blaue.

Grunsätzlich gilt - Passivierung funktioniert nur bei Stateful-Session-Beans. Das ganze wird auch durch den Container, in deinem Fall JBoss, gesteuert. Der kümmert sich drum, dass die Bean passiviert und wenn sie wieder gebraucht wird auch entsprechend aktiviert wird. Einige mögliche Fehlerquellen in dem Zusammenhang wären zum einen die Bean selber, deren zu passivierender Zustand nicht vernünftig serialisiert werden könnte und zum anderen die Timeout's des Containers. Wenn sich da längere Zeit nichts tut - Standard sind imho bei JBoss 30 minuten - geht er davon aus, dass die Bean nicht mehr benötigt wird, da die Verbindung zum Client abgerissen ist bzw. der Client keine mit @Remove annotierte Methode aufgerufen hat und übergibt das Ding dem Garbage Collector.

Ansonsten kann ich dir leider ohne weitere Informationen auch nicht mehr sagen. Die Gründe für den Fehler können wie gesagt manigfaltig sein :).
Edit: Hier findest du einige Informationen, wie du die Passivierung von Stateful Session Beans im JBoss unterbinden/konfigurieren kannst.

Grüße
THMD
 
Zuletzt bearbeitet:
Also es wird bestimmt der Fehler mit der Serialisierung sein. Ich habe ein Stateful-Bean mit z.B. einer Listen-Variable. Der Timeout tritt nach 30 Minuten ein, daher kann es eigentlich kein Timeout sein. Den Timeout in JBoss habe ich auch auf 31 Minuten gestellt.

Was muss man denn beachten, wenn so eine Bean passiviert wird? Oder kann man generell verhindern dass JBoss Varialben passiviert?

Werde die Fehlermeldung noch nachreichen. Bekomme den Fehler gerade nicht nachgestellt, aber er ist noch da :confused:
 
Also wenn der Fehler eintritt bekomm ich eine Seam Debug Page angezeigt., mit folgendem Text:

Hallo,

ja du hast Probleme mit der Serialisierung

Code: 
Caused by: java.lang.RuntimeException: java.lang.RuntimeException: org.jboss.serial.exception.SerializationException: Could not create instance of oracle.jdbc.driver.T4CConnection - oracle.jdbc.driver.T4CConnection
	at org.jboss.ejb3.interceptor.LifecycleInterceptorHandler.postActivate(LifecycleInterceptorHandler.java:152)
	at org.jboss.ejb3.stateful.StatefulContainer.invokePostActivate(StatefulContainer.java:409)
	at org.jboss.ejb3.stateful.StatefulBeanContext.postActivate(StatefulBeanContext.java:388)

Du hälst irgendwo eine Connection in deiner StatefulSessionBean, die er dann beim aktivieren nicht mehr herstellen kann. Warum auch immer du eine Connection serialisierst, hier wäre ein möglicher Lösungsansatz.

Mach die Connection transient, dann wird sie auch nicht mitserialisiert. Erzeuge dir eine mit @PostActivate annotierte Lifecycle-Methode in deiner StatefullSessionBean, welche dann die Connection nach dem Aktivieren wieder neu erzeugt.

Alternativ - schmeiss die Connection als Variable raus - und benutze eine mit @Resource annotierte DataSource. Die sollte zumindest vernünftig passiviert und aktiviert werden und von der kannst du dir dann einfach eine Connection holen, wenn du sie brauchst.

Grüße
THMD
 
Vielen Dank für die schnelle Antwort. Ja jetzt wo du mir die Stelle gezeigt hast ist mir auch klar was die Fehlermeldung genau meint ;-]

Wenn ich die Connection transient setze muss ich dann auch die Methode mit @PostActivat inmplementieren? Oder reicht es wenn die Connection nicht mehr zerstört wird?

Mein Problem sit das die Connectiono einen select for update nowait enthält und der nicht verschluckt werden darf.
 
Hallo,

wenn du die Connection transient setzt, wird sie trotzdem zerstört - sie wird nur nicht mit serialisiert. Beim deserialisieren wird dann die Referenz der Connection auf null gesetzt und du müsstest Sie in der @PostActivate Methode wieder neu erzeugen.

Da du die Connection offenhalten willst, wird dir diese Lösung nix bringen. Schau dir nochmal den Inhalt von dem Link an, den ich in meiner ersten Antwort gepostet habe. In dem Wiki-Eintrag sind mehrere Möglichkeiten erwähnt, wie du die Passivierung einer StatefulSessionBean im JBoss steuern kannst.

Wenn du z.B. die Passivierung einer StatefulSessionBean komplett verhindern willst, kannst du ihr folgende Annotation mitgeben
Code: 
@Cache(org.jboss.ejb3.cache.NoPassivationCache.class)
Damit wird sie dann nie passiviert - was aber auch bedeutet, dass du sicherstellen musst, dass der Client am Ende der Session auch wirklich eine mit @Remove annotierte Methode aufruft, weil ansonsten die Bean im Speicher bleibt und dann auch nicht mehr nach einem Timeout etc. entfernt wird.

Ach ja die in dem Wiki-Eintrag erwähnten Annotationen bzw. Einstellungen sind JBoss spezifisch. Wenn du das ganze also irgendwann auf einem anderen Application-Server nutzen willst, musst du schauen, wie der das macht.

Grüße
THMD
