I am trying to get a simple hibernate mapping to work with JUnit. There is a 'Preferences.java' and 'Preferences.hbm.xml' file and 'hibernate.cfg.xml'. However, I get a mapping exception saying that 'Preferences.hbm.xml' cannot be found.
1. I've checked the classpath. It's OK. 2. The '<id/> tag in 'Preferences.hbm.xml' looks like this:
<id
name="id"
type="java.lang.Integer"
column="ID" >

<generator class="sequence"/>
</id>


... and it works when using it in Tomcat. However, using it in JUnit causes problems. Here's the exception output:

1) testCreate(net.rnet.ut.TestPreferences)junit.framework.AssertionFailedError: <<< MappingException occured: Error reading resource: net/rnet/db/Preferences.hbm.xml
at net.rnet.ut.TestPreferences.testCreate(Unknown Source)

I'd appreciate any ideas from someone who's resolved this before. There seem to be too many obscure classpath issues for hibernate.

nothing special for hibernate here....you are loading a resource in 2 different environments...have you tried to add a / in front to ensure it is a absolute path instead of a relative one.

And have you checked if the hbm.xml files is really at that position in the failing environment ?

I had to remove a lot of directories in the classpath and now my test is working. Thanks for the hint.
