SharePoint List Service Recursive not working

I am using the following code to retrieve the documents in a list. Its working fine. However, it only returns documents and folders in root of the doc library. Is there any thing wrong I am doing here? I am looking for files in sub folders with recursive mode.

    service.setMaintainSession(true);
    call    = (Call) service.createCall();
    call.setTargetEndpointAddress( new java.net.URL("<host>/_vti_bin/lists.asmx") );

    call.setOperationName(new QName("http://schemas.microsoft.com/sharepoint/soap/","GetListItems"));
    call.setProperty(Call.SOAPACTION_USE_PROPERTY, new Boolean("true"));

  call.addParameter(new javax.xml.namespace.QName("http://schemas.microsoft.com/sharepoint/soap/", "listName"),
    new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string"),
    java.lang.String.class,
    javax.xml.rpc.ParameterMode.IN);

   MessageElement me = 
        new MessageElement(new QName("QueryOptions"));
    me.addChildElement(new MessageElement(new QName(
    "IncludeMandatoryColumns"))).addTextNode("true");
    me.addChildElement(new MessageElement(new QName(
    "ViewAttributes"))).addAttribute(javax.xml.soap.SOAPFactory.newInstance().createName("Scope"), "Recursive");

    MessageElement[] me1 = {me}; 

    String strMyString = ""
        + "<Query>"
        + "<OrderBy><FieldRef Name=\"ows_Modified\" Ascending=\"TRUE\" /></OrderBy>"
        + "</Query>";

        MessageElement[] meArray = { getMeFromString(strMyString) };// Array


    call.addParameter("query",org.apache.axis.Constants.XSD_SCHEMA,

            javax.xml.rpc.ParameterMode.IN);    

    call.setReturnType(org.apache.axis.Constants.XSD_SCHEMA);

   Schema ret = (Schema)call.invoke(new Object[] {"listGUID",meArray, me1 });


   public org.apache.axis.message.MessageElement getMeFromString(final String strMyString) {
