Just a note, be careful about recursively calling a macro... You will
eventually get a stack overflow. I did something like this with a
simulated for-loop using Ant Contrib's Math task. I found after around
300 - 400 iterations I'd get a stack overflow...

Hi,
I have the following problem I try to solve in ant.
I should check a www server for a certain result each minute.
I should keep on checking until a desired result is given ( the file
downloaded should exceed a certain limit )
In addition it should have a kind of timeout so it it will return if it
has tried too many times.
I I have made a ant macro which calls itself recursively since there is
no <while> task
I have also access to a <if> task so I manage to check if I have got the
wanted result
But as mentioned I would like to have a timeout, by counting up a
parameter which is given to the recursive macro.
Is this possible ?
I have not seen any <add> or <math> task.
Do some of you have better suggestions for solving this ?
Note, I cannot use <waitfor> task, because I have to check not only for
error code on the response, but the text itself( I manage whith checking
the length of the file downloaded >
To summarize my questions:
- Can I add to variables/properties and but the result in a third
property ?
- Is there a better way than recursive macro to achieve the effect of
<while> looping ?
