Copy the freemarker templates out the the hibernate-tools.jar into you maven directory tree (${basedir}).
In maven:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>hibernate3-maven-plugin</artifactId>
<componentProperties>
...
<templatepath>${basedir}/templates</templatepath>
<template>${basedir}/templates/pojo/Pojo.ftl</template>
</componentProperties>
</plugin>
The template needs to refer to the parent template, the rest is included automaticly.
Howto customize the freemarker templates
Example:
To pick up from a hibernate template (*.hbm.xml):
<property column="TestField" type="integer" name="testField">
<meta attribute="annotation">@XmlElement</meta>
</property>
And generate:
@XmlElement private Integer testField;
Add this in PojoFields.ftl:
<#if pojo.hasMetaAttribute(field, "annotation")>
${c2j.getMetaAsString(field, "annotation","\n")}
</#if>
${pojo.getFieldModifiers(field)} ${pojo.getJavaTypeName(field, jdk5)} ${field.name}<#if pojo.hasFieldInitializor(field, jdk5)> = ${pojo.getFieldInitialization(field, jdk5)}</#if>;
</#if>
