Description:
I have written an Ant task that generates the hibernate.cfg.xml file. 

This can be usefull either as a standalone Ant task or one can write a more generic Hibernate tool and then write a Ant task for it (like hbm2java).

Background:
I use middlegen to generate all the mapping files from my database. This gives me one mapping file for each table, but middlegen does not update the hibernate.cfg.xml file.

This task will scan a directory (or filesets as it is called in Ant) and fill in the correct mappings that it finds.

Usage:

1. The class that defines the task must be defined (by using taskdef).
2. The "dest" attribute is the destination for generated config file.
3. <sfproperty name="" value=""/> is the session factory properties.
4. <mapping dir=""/> is the folder where the mapping files can be found. Note that this is a fileset so you could write something like:

<mapping dir="my_mapping_folder>
  <include name="**/*.hbm"/>
  <exclude name="**/Testtable.hbm"/>
</mapping>

<target name="updatehibernateconfig">  
  <taskdef name="hibconfig"
    classname="no.nr.ant HibernateConfigFileTask"/>  
  <hibconfig dest="hibernate.cfg.xml">    
    <sfproperty name="connection.datasource"
      value="java:comp/env/jdbc/hibernate"/>    
    <sfproperty name="show_sql" value="false"/>    
    <sfproperty name="dialect"
      value="net.sf.hibernate.dialect.SybaseDialect"/>
    <mapping dir="mapping_dir"/>
  </hibconfig>
</target>


Some limitations:
* Only "mapping resource" is supported (not jar or file). And I don't know what they mean.
* It uses the 2.0 version of the DTD (http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd). It should be designed so that it can easily support new DTD's.
