title: Creating SAR file with Ant
body: <p>I am reworking a build, and notice that the ear file contains a Service archive file (sar). I'd like to build the sar file in Ant. I suspect I could probably use the <code>ear</code> or <code>zip</code> task to do this, and simply name the file as <code>*.sar</code>. However, I want to be sure that this will work.</p>
  
  <p>What task would I use in Ant to create a SAR file?</p>
