Tomcat/Hibernate servlet hibernate.cfg.xml not found
Mark Wuest
(jsp's accessing java classes which have the jdbc code).
I would like to migrate to persistent java beans using hibernate
(www.hibernate.org).
I have successfully installed hibernate 2.1.2 and created persistent
objects in a standalone program.
When I attempt to do so in a servlet under tomcat, this line:
sessionFactory = new
Configuration().configure().buildSessionFactory();
throws a HibernateException, "/hibernate.cfg.xml not found".
In my WEB-INF/classes folder, I have:
-HibernateUtil.java/class (containing the above line, pasted from the
hibernate docs)
-hibernate.cfg.xml (the file it cannot find)
-Member.java/class (an ordinary javabean)
-Member.hbm.xml (the mapping file to my table for the above javabean)
-Membership.java/class (the servlet calling the method containing the
offending line)
for your pleasure, here is my hibernate.cfg.xml:
----
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration
PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="connection.datasource">java:comp/env/jdbc/Membership</property>
<property name="show_sql">false</property>
<property name="dialect">net.sf.hibernate.dialect.MySQLDialect</property>
<!-- Mapping files -->
<mapping resource="Member.hbm.xml"/>
</session-factory>
</hibernate-configuration>
----
the offending lines in HibernateUtil.java:
----
try {
sessionFactory = new
Configuration().configure().buildSessionFactory();
} catch (HibernateException ex) {
throw new RuntimeException("Exception building
SessionFactory: " + ex.getMessage(), ex);
}
----
'Sorry to ask what may be a n00b question, but I've googled and
searched and run out of places to look. Or think I have...
Is their some simple common cockpit error everybody but me knows about
that would cause this?
Thanks!
