Hallo,

ich sitze seit fast 3 Tagen an einem Problem.

Ich schreibe eine kleine Web-Application mit Struts und Hibernate.

Den Grundaufbau der Application habe ich aus einem Projekt übernommen, welches hier im Hause schon zuvor geschrieben wurde und problemlos läuft.

Ich habe nun eine kleine Loginmaske, in der Username und Passwort eingegeben werden müssen. Diese Daten werden dann, entsprechend einer HQL-Query, in der DB verifiziert.

DOch hier kommt das ganze ins schleudern: Bis zur DB schafft es meine Query garnicht, denn davor schmeisst mir Hibernate eine riesen Exception dass keine Session vorhanden ist. Was ich persönlich sehr sehr merkwürdig finde, da ich mit einem unserer erfahrenen Java- und Web-Entwickler über mein komplettes Grundmodell geschaut hatte und an sich ist dort alles richtig konfiguriert.

Nur hat sich scheinbar ein kleiner Fehler eingeschlichen, den ich aber - wie den Wald vor lauter Bäumen nicht - mehr sehe, da ich so ziemlich jede Seite durchsucht habe, die sich mit dem Inhalt der Exception beschäfitgt. Auch die Suche hier im Forum hat mir nichts gebracht.

Genauso wenig hatte ich Erfolg mit den Dokus zu Hibernate, mit bereits fertigen Projekten, die ich mir geladen hatte, noch wo anders.


Also, hier erstmal die Exception:

Code:

Ich nutze Hibernate 3 und Struts2.

Auffällig an der Sache ist, dass die Exception jedes Mal geschmissen wird, wenn sich die SessionFactory die aktuell Session mit dem Methodenaufruf

Code:
sessionFactory.getCurrentSession().createQuery(hql)


holen und eine Query absetzen will.


Ich hoffe mir kann jemand dabei helfen.

klingt, als sollte es

<property name="current_session_context_class">thread</property>

statt

<property name="current_session_context_class">managed</property>

heissen?

HI,

also diese Änderung hat schonmal was bewirkt, ich kann nun meine Session auslesen und somit prüfen, ob Sie überhaupt vorhanden ist.

Danke dafür!

Aber nun stehe ich vor der nächsten Exception, die mir rein vom sprachlichen her schon eindeutig ist,aber ich verstehe nicht so ganz, wo denn nun meine "Transaction" fehlt ?

Hier die Exception:

Code:

Bzw., warum habe ich keine aktive Transaction? Ich bin bisher davon ausgegangen, dass ich manuell keine Transaction öffnen muss ?

Wie du vermutlich ahnst, ist dies falsch. Sämtlich Aktionen mit einer Datenbank müssen innerhalb einer Transaktion stattfinden (das ist eine Eigenschaft zumindest aller mir bekannten Datenbanken). Alle Datenbanken, die ich kenne starten Transaktionen zumindest für Selects automatisch, ohne das man etwas dafür tun muss.

Hibernate hat sich dafür entscheiden, dass man eine Transaktion explizit starten muss.

session.beginTransaction()

sollte es tun.

Jens

Hallo,

ich hatte Deinen Post erst später gelesen, als ich den selben Aufruf durch etwas Googeln gefunden habe.

Aber nichts desto trotz, hast Du mir sehr weiter geholfen!

Vielen Dank!

Inzwischen läuft alles ienwandfrei.
