Hi
I'm trying to teach myself Hibernate and have been following a couple of online tutorials. However, I am getting an error which I can't fix....can anybody shed any light ?!?
I have the following hibernate.cfg.xml file....
Code:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">dbc:hsqldb:hsql://localhost</property>
<property name="connection.username"></property>
<property name="connection.password"></property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.HSQLDialect</property>

<property name="current_session_context_class">thread</property>

<mapping resource="uk/co/yahoo/wjday/bean/LoginBean.hbm.xml"/>
</session-factory>
</hibernate-configuration>
and the following MatchBean.hbm.xml file.....
Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<many-to-one name="opposition"column="opposition_id"
class="ClubBean"/>
<many-to-one name="competition"column="competition_id"
class="CompetitionBean"/>
</class>
</hibernate-mapping>
I am trying to get Hibernate to create the Java classes for me from these mapping files using the following build script....
Code:
<?xml version="1.0"?>
<project name="maggies" default="dist" basedir=".">

</project>
However, when I invoke the 'codegen' target, I get the following error...
Code:
C:\development\mags>ant codegen
Buildfile: build.xml
codegen:

[hibernatetool] Check the following:
[hibernatetool]
[hibernatetool] 1) Is the spelling/casing correct ?
[hibernatetool] 2) Is uk/co/yahoo/wjday/bean/MatchBean.hbm.xml available vi
a the classpath ?
[hibernatetool] 3) Does it actually exist ?
BUILD FAILED
C:\development\mags\build.xml:57: org.hibernate.MappingNotFoundException: resour
ce: uk/co/yahoo/wjday/bean/MatchBean.hbm.xml not found
Total time: 5 seconds
C:\development\mags>
The files definately exist and the casing is correct. Do the *.hbm.xml files have to be on the classpath? The *.hbm.xml and hiberanate.cfg.xml are all under the same project root (I have hibernate.cfg.xml under WEB-INF and the individual *.hbm.xml files in a src sub-directory).
I know that the hibernate.cfg.xml is being found, since if I swap the order of the *.hbm.xml files, the exception complains about a different mapping files not being found (i.e. the first one in the file).
Can anybody spot anything obviously wrong with the above? Your help is greatly appreciated !
