I created a time management system (webapplication) with the struts and hibernate framework. Everything works fine (saves, inserts, updates deletion of data) but sometimes, but not always users get following Exception, right after the login:

It should check if the password is correct for the username and then bring up the next page...
What I cannot understand is why it mentions
com.ris.db.det.DetErfassung as this view/mapping file isn't used at this point, it has nothing todo in the login process.
Can this happen when there is a generel error with this mapping file? But, it works.. when this file is used at the point it is really USED everything works fine. As said.. the error occurs not everytime the users tries to login, hibernate bug?
Here is the mapping file (DetErfassung.hbm.xml):
Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

maybe this helps too, the classes:
Code:
package com.ris.db.det;
