The cgen Ant task is very flexible. I have generated entire web
applications directly from the database model using cgen ant task and
templates. I think the modeler now supports most of the cgen ant
task options and you can also use the modeler if you want.
Here's a couple of examples:
<target name="entity stub" depends="failure check"
description="internal:generate entity stub">
<mkdir dir="${dataMapModelPackageDir}/entity/stub/generated"/>
<cgen map="${template.datamap}"
additionalMaps="${additional.template.datamaps}"
version="1.2"
makepairs="false"
overwrite="true"
mode="entity"
outputPattern="_*StubImpl.java"
destDir="${dataMapModelPackageDir}/entity/stub/generated"
superpkg="${dataMapModelPackage}.entity.cayenne.generated"
template="${template.superclass.stub}"
usepkgpath="false">
</cgen>
<mkdir dir="${dataMapModelPackageDir}/entity/stub"/>
<cgen map="${template.datamap}"
additionalMaps="${additional.template.datamaps}"
version="1.2"
makepairs="false"
overwrite="false"
mode="entity"
outputPattern="*StubImpl.java"
destDir="${dataMapModelPackageDir}/entity/stub"
superpkg="${dataMapModelPackage}.entity.cayenne.generated"
template="${template.subclass.stub}"
usepkgpath="false">
</cgen>
</target>
<vppconfig id="vppconfig.datamap" >

</context>
<engine>
<property key="file.resource.loader.path" add="yes"
value="${java.templates}" />
</engine>
</vppconfig>
<target name="datastore interface" depends="failure check"

destDir="${framework-cayenne.java.src.generated}/datastore"

<mkdir dir="${dataMapModelPackageDir}/business"/>
