i wrote a java program myself to put my items on my ebay shop. My java program uses the soap service (AddFixedPriceItemCall) with the help of the ebay sdk jars (WSDL version 981) to add items to my shop. Unfortunately i get 487 error for many items. Some items are added without error. I'm generating the uuid and sku. They are defintely not longer than 32 digits and contain only numbers (e.g. UUID=1622190013 SKU=1321919426). So where is the problem?
