Hi,

This is probalbly something silly.
I have succesfully reversed som tables from postgres.
However when I try to create a sessionFactory the console canot find the xml mapping files.
They are ( like the example ) in my project folder /src/com/wer
the config xml is there also.
In the configuration of the console, I selected these files where is say 'mapping files' but that doesn't help.

I did have a look at the existing posts, but could not find an answer.
Needless to say I am a newbie.

Could somebody help me out?

Thanks.

Hibernate version:
3

Mapping documents:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC

Name and version of the database you are using:
Postgres 8

you should not add mappings that duplicates what is in hibernate.cfg.xml - that will result in duplicate mappings errors.

But your error I assume is caused by not having your hbm.xml files in the classpath of the console. You need to add that in the console otherwise it cannot find it.

Max, thank you for pointing me in the right direction.
- The classpath of the console conguration has to include the location of the compiled classes ( which also has the mapping files ), I had included the source directory...

Sorry to bother again you but I have now progressed to another problem.

Artifact Genaration
After generating the artifacts from the database,
when starting the sessionFactory it throws an UnsupportedClassVersionError for one of the classes created by the tool.

Configuration
JRE_LIB j2re1.4.2_06
eclipse -vm j2re1.4.2_06/bin/javaw.exe
platform XP - update2

hybernate version 3
Database Postgres 8

Solved my UnsupportedClassVersionError by doing everything with java1.5

Run eclipse with java 1.5 ( eclipse.exe -vm JAVA1.5HOME )

THanks for the attention.
