updating jars

[Rick Szeto]

Hi,
    I have been encountering problems with inserting/updating files into exsting
jars, as the Jar task replaces the exisiting one with an empty jar. Try to do it
the hard way also fails for some reason, via exec:

    <exec executable="${java.home}\bin\jar.exe">
      <arg line="uf ${dist.dir}\project-ejb.jar
${src.root}\com\mycompany\project\common\filetoinsert.properties" />
    </exec>

Anything wrong with the above call? Or any solution to the problem?
Any help would be greatly appreciated
