Hi,

This will work.

public static OMElement createQuery(){
        OMFactory factory = OMAbstractFactory.getOMFactory();

OMNamespace aon = factory.createOMNamespace(" http://www.aoi.com/WSDA/0.1","ao";); OMElement wsdaQueryNode = factory.createOMElement("wsdaQuery", aon, null); wsdaQueryNode.addAttribute("name", "campaign.getProductSkuId ", aon);

        OMElement param = factory.createOMElement("param", aon, null);
        param.addAttribute("skuId", "6949", aon);
        wsdaQueryNode.addChild(param);
      return wsdaQueryNode;
}

    Hi,
    I am trying to add a simple child element to an OMElement I have
    created, but I am getting a null pointer. I am using the same syntax I
    have seen in the Axiom OM Tutorial
    ( http://ws.apache.org/axis2/1_0/OMTutorial.html), and am using
    Axis 2 1.3.

    The code I try is:

    public static OMElement createQuery(){
           OMNamespace aon = new
    OMNamespaceImpl(" http://www.aoi.com/WSDA/0.1";, "ao");
           OMElement wsdaQueryNode = new OMElementImpl("wsdaQuery",
    aon, null);
           wsdaQueryNode.addAttribute("name",
    "campaign.getProductSkuId ", aon);
           OMElement param = new OMElementImpl("param", aon, null);
           param.addAttribute("skuId", "6949", aon);
           param.addChild(param);
           return wsdaQueryNode;
    }

    The error I get is:

    java.lang.NullPointerException

    Any ideas would be much appreciated.
