Thanks again !!!
I'm looking at your last hint:
<script>
check your existing properties etc. ...
set new properties you need for further processing via use of ant api
<script/>
but I don't know how to use it.
My ant version is: Apache Ant version 1.6.5 compiled on June 2 2005 and
I read that script task depends on external libraries not included in
the Ant distribution.
So I choose the "lowlevel" approach:
<echo file="tmp.properties">pollerValue=${pollerValue}</echo>
The properties file is created:
/tmp> cat tmp.properties
pollerValue=bnk01alm01
but then
<property name="pollerValue" value="${pollerValue}"
file="tmp.properties"/>
doesn't work. I'm trying to understand why ...
Regards
Patrizio

Subject: RE: how to check that a property exist
/*
Hi Gilbert,
issue ii) solved using macrodef:
<target name="pollerEventIsSet-if" depends="check-pollerEventIsSet"
if="pollerEventIsSet">
<macrodef name="propertycopy">
<attribute name="pollerEvent"/>
<sequential>
<property name="pollerValue" value="[EMAIL PROTECTED]"/>
</sequential>
</macrodef>
<propertycopy pollerEvent="${IPEvent}.pollerManagedServer"/>
<echo>pollerEventIsSet, pollerValue: ${pollerValue}</echo>
</target>
output:
pollerEventIsSet-if:
[echo] pollerEventIsSet, pollerValue: bnk01alm01
Any idea about issue i) ?
*/
issue ii) =
i believe that's solution which is also listed in the ant faq
as far as i remember
issue i)
the problem is you're using antcall which opens a new project scope
means after antcall is through the project scope is gone and you
don't get back anything to the calling target.
therefore tasks like AntCallBack, AntFetch exist in antcontrib ;-)
possible solutions =
very lowlevel = echo value to a file and load it in the calling target
/*
thanks a lot for your hint but I would like to find a way without using
antcontrib...
*/
go with antcontrib - i see you're already using it, as propertycopy
is part of the antcontrib task suite ;-))) and adapt my snippet to your
needs
or finally - recommended - use
<script>
check your existing properties etc. ...
set new properties you need for further processing via use of ant api
<script/>
Regards, Gilbert
