Hallo everybody,

Hibernate version 3.2.6
Eclipse Europa 3.3.1
Java 1.5.0
Apache Ant 1.7.0

I'm new in hibernate and I'm trying to start from hibernate tutorial and to make first example in documentation, but at 1.2.6. Loading and storing objects from hibernate documentation I have problem:

[javac] Compiling 2 source files to D:\MyProjects\HibernateTest\bin

BUILD FAILED

Please help me.

Did you add the hibernate3.jar and other dependent libraries from hibernate download to your classpath?

Yes all of 9 basic libraryes I put in classpath:

antlr.jar
cglib.jar
asm.jar
asm-attrs.jars
commons-collections.jar
commons-logging.jar
hibernate3.jar
jta.jar
dom4j.jar
log4j.jar

Could you show us the build.xml?

<project name="Testhibernate" default="compile">

<property name="sourcedir" value="${basedir}/src"/>
<property name="targetdir" value="${basedir}/bin"/>
<property name="librarydir" value="${basedir}"/>

<path id="libraries">
<fileset dir="${librarydir}">
<include name="*.jar"/>
</fileset>
</path>

<target name="clean">
<delete dir="${targetdir}"/>
<mkdir dir="${targetdir}"/>
</target>

<target name="compile" depends="clean, copy-resources">
<javac srcdir="${sourcedir}"
destdir="${targetdir}"
classpathref="libraries"/>
</target>

<target name="copy-resources">
<copy todir="${targetdir}">
<fileset dir="${sourcedir}">
<exclude name="**/*.java"/>
</fileset>
</copy>
</target>

<target name="run" depends="compile">
<java fork="true" classname="events.EventManager" classpathref="libraries">
<classpath path="${targetdir}"/>
<arg value="${action}"/>
</java>
</target>


</project>

I have never used the classpathref but looks good(i take note). what i do in my ant projects is use classpath inside the javac task like

<!-- compile sources -->
<javac srcdir="${servlet.src}"
destdir="${servlet.dist}"
debug="on" target="1.5"
fork="yes"
executable="${.....}"
>
<classpath>
<fileset dir="${servlet.general_lib}">
<include name="**/*.jar"/>
</fileset>
<pathelement path="${project.root}/dist/dal.jar"/>
<pathelement path="${project.root}/mas/dist/gatewayAgent.jar"/>
<pathelement path="${project.root}/mas/dist/jadeOntology.jar"/>
<pathelement path="${project.root}/mas/dist/agentGenerator.jar"/>
</classpath>
</javac>

and works.

But is better your use of classpathref, you could try to run ant with -d option (debug mode) and add to your ant task debug and debuglevel take a look at the ant manual:

http://ant.apache.org/manual/CoreTasks/javac.html

You could also check with <echo>${targetdir}</echo> if your references are correct, some times this is the key.

i hope it helps.

With these options ant will output to the console all the debug (usefull) information, check if you are loading all of the libraries you need.
