the build.xml in Middlegen-Hibernate-r5 is
<?xml version="1.0"?>

This is a testing platform for the middlegen hibernate plugin. It is a stripped
down version of the samples application. At the moment it is only concerned
with the generation of the mapping documents so that various tests etc can be
done on the generated package.

The DOCTYPE declaration declares the location of product-specific parts of the
Ant build file. You can change the values of these declarations to point to
other available files. This gives you an opportunity to choose what database.

Note that this syntax has noting to do with Ant or Middlegen. This
is the standard way defined by w3c to dynamically include external
files in an XML document. Any decent XML parser will do the include
transparently. Try to open this file in Internet Explorer and see
for yourself.

We can specify what tables we want Data generated for.
If none are specified, Data will be generated for all tables.
Comment out the <table> elements if you want to generate for all tables.
Also note that table names are CASE SENSITIVE for certain databases,
so on e.g. Oracle you should specify table names in upper case.
<!--table generate="true" name="flights" pktable="flights_pk"/>
<table name="reservations"/-->

If you want m:n relations, they must be specified like this.
Note that tables declare in multiple locations must all have
the same value of the generate attribute.
<tablea generate="true" name="persons"/>
<jointable name="reservations" generate="false"/>
<tableb generate="true" name="flights"/>

<!-- Plugins - Only Hibernate Plugin has been included with this special distribution -->

If you want to generate XDoclet markup for hbm2java to include in the POJOs then
set genXDocletTags to true. Also, composite keys are generated as external classes which is
recommended. If you wish to keep them internal then set genIntergratedCompositeKeys to true.
Since r4 the ability to customise the selection of JavaTypes is now provided. The is a
recommended type mapper provided as shown. It is optional - if not provided then Middlegen
itself will select the Java mapping (as it did previously).
These settings are optional thus if they are not define here values default to false.
