Scott & Chris,
I have added the following config file to my classes directory and still get
the same
exception trace (hibernate.config.xml):
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd";>
<hibernate-configuration>
<!-- a SessionFactory instance listed as /jndi/name -->
<session-factory name="java:comp/env/hibernate/SessionFactory">
<!-- properties

<property
name="dialect">net.sf.hibernate.dialect.SQLServerDialect</property>
<property name="show_sql">true</property>

<property name="transaction.factory_class">

<property name="transaction.manager_lookup_class">

<property name="jta.UserTransaction">java:comp/UserTransaction</property>
-->
<!-- mapping files -->

</session-factory>
</hibernate-configuration>
Thanks Again!!!!

Are your .hmb.xml files listed in your main hibernate config file? Many times,
I've forgotten
to add these after generating the hbm.xml files via xdoclet.

Subject: Re: [cinjug-users] Hibernate Newbie Question
It does look like it is not finding your .hbm.xml
files. These files should be place next to the class
files, ie the hbm file for class com.blah.Foo would go
in the classes dir at com/blah/Foo.hbm.xml. I do this
by calling xdoclet and telling it to generate into my
source dir and then copy these files over to the
classes directory in my compile target.
Hibernated classes absolutely can be tested in a dev
environment, but you may need to use a different
configuration file to tell it to just connect thru
JDBC and not get the connection from the datasource.
Myself, I just run my junit test cases in the
appserver locally using cactus and DBUnit and that way
i just have one config file.
