Adding classpath in J2ME build.xml

I have a build.xml as follows. I wanted to specify dependency on kxml.zip in class path in this file. How do I do that?

<project name="MyMobile" default="j2mepolish">
      <!--define the installation folder of J2ME Polish-->
      <property name="polish.home" location="C:\Tools\J2ME-Polish" />
      <!--define the installation folder of the WTK-->
      <property name="wtk.home" location="C:\S60\Devices\S60_3rd_MIDP_SDK" />
        <property name="nokia.home" location="C:\S60\Devices\S60_3rd_MIDP_SDK" />
               
      <!-- Definition of the J2ME Polish task:   -->
            <taskdef name="j2mepolish"
                  classname="de.enough.polish.ant.PolishTask"
                  classpath="${polish.home}/import/enough-j2mepolish-build.jar:${polish.home}/import/jdom.jar"
            />
               
         

      <!-- start the build with J2ME Polish -->
