    Hallo zusammen,

    ich habe folgendes Problem. Tritt beim Ausführen der Methode indiziereImage(..) eine Exception auf wird kein Rollback durchgeführt. Langsam fällt mir nichts mehr ein, was ich noch ausprobieren könnte um die Transaktion samt Rollback Richtig ans laufen zu bekommen. :( Ich finde den Fehler einfach nicht.

    Hallo,

    hmmm... wenn du get* Methoden mit read-only=true deklarierst... was möchtest du denn noch im Roll-Back machen? Btw. hast du für inidiziereImage(...) überhaupt Rollback konfiguriert?
