Hi atish,

There are a couple of things you can do so that we can locate the problem
more precisely. First of all you can post the content of the file you are
trying to cactify.
Is it a big one - give a brief description of it. Also what is the type of
your OS (I
guess you are using Windows) and the version of the JVM.

Also try downloading Ant 1.6.5. (!!! Don't download the latest Ant release,
we have problems with
Ant 1.7 !!!) and post the result with that version of Ant.

Hope that helps.
