This a piece of my Ant file :

<xdoclet destdir="./../../srcGeneration" force="true" verbose="true">
<fileset dir="./../../srcGeneration">
<include name="com/**/Adresse.java" />
</fileset>
<template templateFile="template/toIDAO.xdt"
havingClassTag="hibernate.class" acceptAbstractClasses="true"
prefixWithPackageStructure="true" destinationFile="I{0}DAO.java"
acceptinterfaces="true"
</template>
</xdoclet>


What i don't understand that the Ant engine started to run the XDoclet jar but it stopped for some reasons.
Firstly , i 'm asking if it is possible or not to run XDoclet to generate Java Classes while my Web Application is runnig.
Then , how can i make sure that the XDoclet jars are been read.
Finally , if someone have an idea of how to resolve this exception i will be grathefull for him if he helps me.
