There's a lot of power in what the <replace> task can do. Here's a very
simple one that replaces the string "@port@" with the port number
specified by the "port" property:
<project name="Create server.xml" default="generate">
<target name="generate" description="Generate customized server.xml">
<replace file="server.xml" token="@port@" value="${port}"
</target>
</project>
In your template server.xml, you'd have a <Connector> element like this:
<Connector ... port="@port@" .../>
Now, you just run "ant -Dport=8085" and you've replaced the port number.
Generalizing this to replace lots of properties is straightforward.
See the Ant docs for more details <http://jakarta.apache.org/ant/>.
