i m a beginner in hibernte. I m trying to build a basic hib progrm with Ant build. i m using hib 3.6.10 ,jboss tools 3.2.2 and apache ant 1.9.0


I get the below error:

E:\hiber\Hib_2\build.xml:21: taskdef A class needed by class org.hibernate.tool.ant.EnversHibernateToolTask cannot be found: org/hibernate/tool/ant/HibernateToolTask
using the classloader AntClassLoader

what could be the possible error? below are my build.xml and build.prop files.

Could anyone help on this? also, i am not sure what path (absolute or relative? if relative, relative to which directory?) to give in build.properties file.

build.xml:

<project name="sample">
<property file="build.properties"/>
<property name="src" location="src"/>
<property name="bin" location="bin"/>
<property name="sql" location="sql"/>
<property name="hibernate.tools" value="${hibernate.tools.home}${hibernate.tools.path}"/>
<path id="classpath.base">
<pathelement location="${src}"/>
<pathelement location="${bin}"/>
<pathelement location="${hibernate.home}/hibernate3.jar"/>
<fileset dir="${hibernate.home}/lib" includes="**/*.jar"/>
<pathelement location="${hsql.home}/lib/hsqldb.jar"/>
</path>
<path id="classpath.tools">
<path refid="classpath.base"/>
<pathelement
location="${hibernate.tools}/hibernate-tools.jar"/>
</path>
