zatial sa mi podarilo vygooglovat ze pravdepodobne hore uvedene verzie 
jednotlivych kniznic nespolupracuju a treba najst tie "spravne" verzie, 
ale kazdopadne tato chyba sa velmi casto objavuje vo forach.

Skoro bych si tipnul, že díky atributu default-lazy-init="true" se vám
ta beana vůbec nevytvořila a k chybě dojde pravděpodobně až když si na
tu beanu (nebo jinou beanu, která se danou beanu odkazuje) šáhnete.
Schválně to zkuste ...

2008/1/9, Ivan Polák <[EMAIL PROTECTED]>:

  

Dobry den,

aby som odstranil moznost problemov s IDE, teraz to kompilujem pomocou
build.xml skriptu a ANT.

java je 1.5.0 a pouzivam tomcat 6.0.14

povodne som mal v subore applicationContext-acegi.xml iba <beans> a
zmenil som to na:

<beans xmlns="http://www.springframework.org/schema/beans";
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
       xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.0.xsd";
       default-lazy-init="true">

a uz tam ta chyba nie je, neviem ci toto ma vplyv, pretoze uz fakt
skusam vsetko ?

Zdravim,

      muzete nam popsat v cem kompilujete (verze + binary kompatible) a na
jakem apl serveru to deployujete (verze javy)? Popr. je to exploded nebo
packed?

Podobne problemy mam nekdy pokud se neschoduji verze jaky vyvojoveho
prostredi (myeclipse) a apl serveru i kdyz tak class tam je zda "ze neni
v classes kdyz ji hleda spring".

Co takhle si hodit breakpoint na AbstractBeanFactory.java:1160
a zkusit si tam inspectnout:
this.getClass().getClassLoader().loadClass("com.house.dao.HibernateAuthenticationDao")
