JAX WS WebService implementation with XSD only

Question

I have an existing SOAP client, that send the SOAP message according to that XSD description. My WebService accept the call, but my Item list is empty.

if I change the WebMethod declaration as

 @WebMethod
public Integer transferPalletRecords2(@WebParam(name = "arg0") List<Item> items) 

Then I receive 1 item with all NULL fields.

DEBUG got [{RESERVED3=null, RESERVED2=null, RESERVED1=null, WAREHOUSENUM=null, LINENUM=null, QUANTITY=null, SHELFLIFE=null, RESERVED5=null, RESERVED4=null, INDICATOR=null, NAME=null, HUIDENT=null, UOM=null, DLV_NO=null, COUNTRYOFORIGIN=null, CITY=null, BATCH=null, MATNR=null, EAN13=null}] items!

Any suggestion what is wrong?

Answer 1

The problem is solved. I've used SOAPUI to generate SOAP request for my WSDL. The solution were:

    @WebMethod
public Integer transferPalletRecords2(PalletRecord2Array palRec) {
    try {
        System.out("Got " + palRec.getItems().size() + " items!");
    } catch (Exception e) {
        e.printStackTrace();
    }
    return 0;
}

// PalletRecord XML Struktur
@XmlRootElement(name = "arg0")
@XmlAccessorType(XmlAccessType.FIELD)
public static class PalletRecord2Array {

    @XmlElement(name = "item", required = true)
    protected List<Item> items;

    public List<Item> getItems() {
        if (items == null) {
            items = new ArrayList<>();
        }
        return items;
    }

}

public static class Item {
...
}

Could you also list the client code? Most of the time when you receive an empty list it's because of a mismatch in the root element name and namespace so make sure they're the same.

Easiest way to find the issue and correct it is to generate a WSDL of your web service and get a template request from a SOAP request program such as SoapUI and once successful from there try to replicate the same SOAP envelope contents on the client side
