<fileset dir="${src.www.dir}/jsp"/>

 

</copy>

 

 

 

10．Javadoc

 

<target name = “javadoc” depends=”compile,jar”>

 

    <mkdir dir = “${doc.dir}/api”/>

 

    <javadoc packagenames = “ myproj.*”

 

        sourchpath = “${src.dir}”

 

        destdir = “${doc.dir}/api”

 

        author = “true”

 

        version = “true”

 

       use = “true”>

    </javadoc>

 

</target>
