There is a typo in line 44

should be

But then it works perfect =)

Line 41 says:
classoath
should be:
classpath

Good job.

Thanks. Updated this. Forgot about this gist completely!

Line 65
fasle > false

---

Thanks!

Thank you for the sample.

PS: I did following, because resulting war archive contained lib twice. because project.lib.dir was under project.web.dir

	<target depends="build" name="package" description="Packagign all files into ${project.war}">
		<war destfile="${project.war}" index="true" needxmlfile="fasle">
			<classes dir="${project.classes.dir}" />
			<lib dir="${project.lib.dir}" />
			<fileset dir="${project.web.dir}">
				<include name="**/*.*" />
                                <exclude name="WEB-INF/lib/**" /> <!-- Added this line -->
			</fileset>
		</war>
