When I run the test is returned me the following error.
Exception in thread "main" org.hibernate.MappingException: Unknown entity: it.s.monitoringDoor.model.Door_Open
[...]
some advice?
Look at the package of your Door_Open class, it is: it.selco.monitoringDoor.model while in hibernate.cfg.xml the Door_Open.hbm.xml file is at: <mapping resource="it/s/monitoringDoor/model/Door_Open.hbm.xml"/>. The package and the mapping resource path do not match, they should be the same e.g. it/selco/monitoringDoor/model/Door_Open.hbm.xml
and of course move the Door_Open.hbm.xml to be in the same path as its class.
Hope this helps.
PS, why are you using both annotations (e.g. #Entity) and hbm mapping for your class? I think you should choose one not both.

Hey i am new to hibernate and java and im getting this exception i tried multiple solutions i found on google and nothing seems to work. Would appreciate any help. I am trying to return number of rows from table in database.

Maybe your mapping file is not complete but other wise it should be:
<class name="com.vaannila.uzytkownik.Uzytkownik" table="uzytkownicy">
=> need to set fully qualified class name (with package)
I think it makes sense to specify full-qualified entity class name:
<class name="com.vaannila.uzytkownik.Uzytkownik" table="uzytkownicy">
Don't forget to mention your class using as a entity classes in hibernate configeration file using the mapping tag !!
Example:
<session-factory>
//database configeration goes here
<mapping class="org.fbis.models.Form3A"/>
</session-factory>
Stijn Geukens answers right,but I want to point out more information about this question.
There are two reasons I know causing this problem: entity class not found
First, As Stijn Geukens answers, Your Hibernate mapping is not right, the value of name attribute for the tag class should be the Java class with package ahead.
Second, if you have boolean filed in your Java class, this field can't start with is.Otherwise, the hibernate throws an exception getter method is not found... when run by Java Debug mode or Run mode.But when it comes to web project and you run your project as Server Application,the message becomes entity class not found.It made me puzzled for a long time.So do not name your boolean field with is ahead.
