First timer with Hibernate - unknown entity error

[Raphael Rissato]

Hi, heres my problem: when I use "cfg.addClass(Tarifa.class)" to map a class I get the following error (since its already mapped at hibernate.cfg.xml):

org.hibernate.MappingException: Error reading resource: Tarifa.hbm.xml
at org.hibernate.cfg.Configuration.addClass(Configuration.java:471)
at TarifaDAO.<init>(TarifaDAO.java:12)
at TesteHib.main(TesteHib.java:10)
Caused by: org.hibernate.MappingException: duplicate import: Tarifa

if I comment the "cfg.addClass(Tarifa.class)", I get the (funny if not tragic) error:

org.hibernate.MappingException: Unknown entity: from Tarifa
at org.hibernate.impl.SessionFactoryImpl.getEntityPersister(SessionFacto
ryImpl.java:569)
at org.hibernate.impl.SessionImpl.getOuterJoinLoadable(SessionImpl.java:
1337)
at org.hibernate.impl.SessionImpl.list(SessionImpl.java:1303)
at org.hibernate.impl.CriteriaImpl.list(CriteriaImpl.java:300)
at TarifaDAO.getList(TarifaDAO.java:24)
at TesteHib.main(TesteHib.java:11)
Press any key to continue...

Please help me if you know whats happening. Tkx!

Can you copy paste your code for hibernate.cfg.xml and Tarifa entity.

<mapping resource="Tarifa.hbm.xml"></mapping>

Where is the Tarifa.hbm.xml placed in your application?

[saranga rao]

Hi,

It is not finding the path of <mapping resource="Tarifa.hbm.xml"></mapping>

get the path and specify ...............the project path

[Raphael Rissato]

Hi... there�s no package in my app. All files class and all xml files are placed at the same dir. Tkx

You might want to create a package com.hibernate.example and put your Java file in it. As well tweak the hbm file's class parameter to
<class name="com.hibernate.example.Tarifa" table="tarifa">
