Utility for creating tables, inserting data through Ant

Hi,

Is a utility available in the PostGreSQL jdbc so that we can run Ant to deploy an application?

The build.xml file for Ant is something like

<target name="db-create-table" depends="init">
  <java classname="COM.postgresql.tools. ..." fork="yes" >
     <jvmarg line="${postgres-jvmargs}" />
     <arg value="${sql}/create-table.sql" />
     <classpath path="${postgres-path}" />
  </java>
  </target>
