Hi Prashant,

I had executed ANT in verbose and debug mode and it shows

 [javac] HelloWorlApp.java added as HelloWorlApp.class doesn't exist.

Whereas the class file exist in dest dir. I tried adding/deleting dest
dir in classpath, but no luck in both the situation.

I would appreciate, If you could try this in your environment. I had
tried this with ANT 1.6.5/1.7 and java 1.4/1.5.

P.S: Other member's can also suggest me something.

Thanks,

Humm..

May be you could try running ANT in verbose mode, see why ANT thinks it
should compile .java files that are not modified.

Also, I think the destination dir the classes are directed to is
automatically added to classpath by ANT. So you may not need this :

> <fileset dir=3D"${dest}"
> includes=3D"**/*.*"/>
> </classpath>
