WLST Ant task not working -- error in finding weblogic.Home

Question

I am attempting to set up a WLST script to automatically set up my domain. The following is a minimal version of the Ant task I'm using:
<wlst debug="true" failOnError="true">
    <classpath>
        <pathelement location="${weblogic10.home}/server/lib/weblogic.jar"/>
    </classpath>
    <script>
        connect('weblogic','weblogic','t3://localhost:5000')
    </script>
</wlst>When I run the target, I get the following error:
java.lang.RuntimeException: error in finding weblogic.Home

     at com.intellij.rt.ant.execution.AntMain2.main(AntMain2.java:17)My weblogic10.home property (referenced in the ant target) points to the weblogic installation directory (C:/bea_10/wlserver_10.0). Weblogic.jar exists in the path specified, and contains the class weblogic.Home.
What am I missing? Any help would be greatly appreciated. I'm using Ant 1.6.5 and Weblogic 10.0 on Windows XP, if that makes a difference.
Thanks in advance!

Hi,
I too have this problem. I am trying to use my own ant installation. The docs say that we can do that. However, if i try to set the domain env then the ant command will point to bea's ant. Anyway I have defined the task using a taskdef as follows
<path id="wl_classpath">
          <pathelement location="${BEA_HOME}/patch_weblogic922/profiles/default/sys_manifest_classpath/weblogic_patch.jar" />
          <pathelement location="${env.JAVA_HOME}/lib/tools.jar" />
          <pathelement location="${WL_HOME}/server/lib/weblogic_sp.jar" />
          <pathelement location="${WL_HOME}/server/lib/weblogic.jar" />
          <pathelement location="${WL_HOME}/server/lib/webservices.jar" />
     </path>
<taskdef name="wlst" classname="weblogic.ant.taskdefs.management.WLSTTask">
          <classpath refid="wl_classpath" />
     </taskdef>
     <target name="start_appinstance" description="--> Starts the Appinstance"
          <wlst debug="true">
               <script>
                    connect('weblogic','weblogic','t3://localhost:7001')
               </script>
          </wlst>
     </target>there is no weblogichome or beahome attribute for this task.
My objective is to control a server using the node manager. I believe the only way to do this is to use wlst and not wlserver.
Thanks

PS: i am using version 9.2MP2 for weblogic and ant 1.7
