Ok, there it is (patch3.txt). Remember: I did not test changes in ant.xml.

> Currently, the POJO java code exporter generates only property access mode Java files, i.e. the JPA annotations are put on the getters only.
> This is done in PojoFields.ftl (which does not contain annotations on fields) and in PojoPropertyAccessors.ftl (which includes the GetPropertyAnnotation.ftl that produces annotations on the methods).
> It would be nice if the hbm2java task generate also field or property access mode entities (with property access mode by default).
> The implementation could be based on the following workaround.
> Workaround:
> ------------------
> 1) extract the following files from the hibernate-tools.jar/ and put them in the /pojo/ directory:
>     PojoFields.ftl
>     PojoPropertyAccessors.ftl
>     GetPropertyAnnotation.ftl
>     Ejb3PropertyGetAnnotation.ftl
> 2) rename GetPropertyAnnotation.ftl to GetFieldAnnotation.ftl and change references from "property" to "field", resulting in the attached file GetFieldAnnotation.ftl 
> 3) rename Ejb3PropertyGetAnnotation.ftl to Ejb3FieldGetAnnotation.ftl and change references from "property" to "field", resulting in the attached file Ejb3FieldGetAnnotation.ftl
> 4) edit PojoFields.ftl to add a conditional inclusion of GetFieldAnnotation.ftl (resulting in the attached PojoFields.ftl):
> -  </#if>	${pojo.getFieldModifiers(field)} ${pojo.getJavaTypeName(field, jdk5)} ${field.name}<#if pojo.hasFieldInitializor(field, jdk5)> = ${pojo.getFieldInitialization(field, jdk5)}</#if>;
> + </#if>
> + <#if exporter.properties.containsKey('jpaAccessMode') && jpaAccessMode.equals('field')>
> + <#include "GetFieldAnnotation.ftl"/>
> + </#if>
> + ${pojo.getFieldModifiers(field)} ${pojo.getJavaTypeName(field, jdk5)} ${field.name}<#if pojo.hasFieldInitializor(field, jdk5)> = ${pojo.getFieldInitialization(field, jdk5)}</#if>;
> 5) edit the PojoPropertyAccessors.ftl to change to a conditional inclusion of GetPropertyAnnotation.ftl (resulting in the attached PojoPropertyAccessors.ftl):
> -     <#include "GetPropertyAnnotation.ftl"/>
> + 	<#if !exporter.properties.containsKey('jpaAccessMode') || !jpaAccessMode.equals('field')>
> +     <#include "GetPropertyAnnotation.ftl"/>
> + 	</#if>
> 6) in the Ant build.xml, add a property <property name="jpaAccessMode" value="field"/> to the <hibernate> tag, for example:
>     <hibernate ...>
>       <jdbcconfiguration .../>
>       <property name="jpaAccessMode" value="field"/><!-- possible values are : field | property ; any other value defaults to property -->
>       <hbm2java ...>
>     </hibernate>
