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>

        <!-- Enable Hibernate's automatic session context management -->
        <property name="current_session_context_class">thread</property>

        <!-- Disable the second-level cache  -->
        <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">true</property>

        <!-- Drop and re-create the database schema on startup -->
        <property name="hbm2ddl.auto">create</property>




        <mapping resource="uk/co/yahoo/wjday/bean/MatchBean.hbm.xml"/>
        <mapping resource="uk/co/yahoo/wjday/bean/NationalityBean.hbm.xml"/>
        <mapping resource="uk/co/yahoo/wjday/bean/PlayerBean.hbm.xml"/>
        <mapping resource="uk/co/yahoo/wjday/bean/PlayerMatchBean.hbm.xml"/>
        <mapping resource="uk/co/yahoo/wjday/bean/ClubBean.hbm.xml"/>
        <mapping resource="uk/co/yahoo/wjday/bean/CompetitionBean.hbm.xml"/>
        <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">

<hibernate-mapping>
     <class name="uk.co.yahoo.wjday.bean.MatchBean" table="MATCH">
         <id name="id" type="long" column="MATCH_ID">
             <generator class="native"/>
         </id>

          <property name="date"         type="date"    not-null="true"/>
          <property name="venue"        type="string"  not-null="true"/>
          <property name="goalsFor"     type="integer" not-null="true"/>
          <property name="goalsAgainst" type="integer" not-null="true"/>
          <property name="matchReport"  type="text"    not-null="false"/>
          <property name="homeKit"      type="blob"    not-null="false"/>
          <property name="awayKit"      type="blob"    not-null="false"/>
          <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=".">

    <!-- Tomcat home directory, the path to where your tomcat is installed -->


    <property name="projname"            value="mags"/>

    </target>


</project>


However, when I invoke the 'codegen' target, I get the following error...

Code:
C:\development\mags>ant codegen
Buildfile: build.xml

codegen:
[hibernatetool] Executing Hibernate Tool with a Standard Configuration
[hibernatetool] 1. task: hbm2java (Generates a set of .java files)
[hibernatetool] log4j:WARN No appenders could be found for logger (org.hibernate
.cfg.Environment).
[hibernatetool] log4j:WARN Please initialize the log4j system properly.

as not found.
[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 !

Bill

Add *.hbm.xml and hibernate.cfg.xml files from your classes directory to your classpath :

<path id="classpath">
<fileset dir="${classes}">
<include name="*.xml" />
</fileset>
<fileset dir="${generateAnnotations}">
<include name="*.jar" />
</fileset>
<fileset dir="${generateHibernate}">
<include name="*.jar" />
</fileset>
<fileset dir="${generateTools}">
<include name="*.jar" />
</fileset>
<fileset dir="${velocity}">
<include name="*.jar" />
</fileset>
</path>
