ok, Dominique - so I haven't missed a description on this subject.
Thanks for pointing me to <script/>

It's worth answering Rolf, but the answer is not good... There is currently
no task that does string manipulation on properties directly. Nevertheless,
you can easily do it yourself using a <script> and any of the
Java-implemented BSF-compatible languages out there: JavaScript, BeanShell,
Jacl, etc... The following below shows you how. This is no substitute for a
good task that would be doing property manipulation, but it does the job
relatively easily (once you have the proper JARs for <script>). --DD
P:\org_apache\antx>%ANT_HOME%\bin\ant -f property-manip-script.xml
Buildfile: property-manip-script.xml
test:
[echo] package name = com.myName.helloWorld
[echo] package path = com\myName\helloWorld
[echo] package class = helloWorld
BUILD SUCCESSFUL

<echo message="package name = ${package}" />

PS: Of course, getting the class name from the qualified
class name is a bit more involved than that to be generic.

Seems that this question is not worth answering or there is no answer it.

Compared with the not-so-good old make utility
I wonder how string handling is done in Ant.
Looked thru the manual and couldn't find it.
E.g.:
Setting properties like
<property name="package" value="com.myName.helloWorld"/>
<property name="packagePath" value="com/myName/helloWorld"/>
<property name="mainClass" value="HelloWorld"/>
are redundant, at least do me.
There has to be a way to base all three on common information.
What have I missed?
