Subject Re: Finding an available port number
Date Tue, 03 May 2011 00:12:41 GMT
THanks, I was aware that I could do it through a Java (or similar) command.
What I've got is an Ant task that initializes there server instance with a
specified port number (unfortunately there's no facility to pass in 0 here).
I was after another task so I could so something like:

<target>
  <getavailableport property="port.number" />

  <createserver .... port="${port.number}" />
</target>

Cheers,
Daniel B.
