You can use a mapper within the unzip task to change the paths written.

<unzip dest="${release.dir}/image/tomcat" src="${tomcat.zip}">
    <patternset>
        <include name="apache-tomcat-6.0.29/*"/>
    </patternset>
    <mapper>
        <globmapper from="apache-tomcat-6.0.29/*" to="*"/>
    </mapper>
</unzip>

<unzip dest="${release.dir}/image/tomcat" src="${tomcat.zip}">
    <patternset>
        <!-- add another star -->
        <include name="apache-tomcat-6.0.29/**"/>
    </patternset>
</unzip>

The following works as long that there is a single directory in the tomcat archive.

<untar src="${release.dir}" dest="${tomcat.tar.gz}" compression="gzip">
  <cutdirsmapper dirs="1" />
</untar>
