<target name="ear" depends="war,ejb,rar">
    <ear destfile="ear/myapp.ear" ...>
        <fileset dir="ejbs" include="*.jar"/>
        <fileset dir="wars" include="*.war"/>
        <fileset dir="rars" include="*.rar"/>
        <fileset dir="libs" include="*.jar"/>

<target name="war" depends="jar">
    <war destfile="wars/frontend.war" ...>
         <!-- all your frontend content -->

<target name="rar"/>  <!-- similar thing as above -->
<target name="ejb"/>

<zip> supports nested <zipfileset src=""/> which merges contents of another
zip file into the new one. JAR is the same format, so you can use that.

Well, lets have look into the source, I thought ...

Yep: <jar> extends <zip>. <ear> and <war> extends <jar>.
Therefore a nested <zipfileset> should be possible. Try it out :-)
