Deat friends,
i am the newer to WSAD.
i use WSAD5.1.1.when i want to generate a wsdl file with a bean .it give s me a error:
WSWS3324E: error:problem of trying to write for org.w3c.dom.Element ; nested exception is: java.lang.NullPointerException
maybe because the bean uses a Element class as a signature.
This is main content of my bean:
*****************************************
public class InquireParts implements Serializable {

public org.w3c.dom.Element inquireParts(String partNumber)throws Exception {}

private Element populatePart(Document doc, PartInventory bean)throws org.w3c.dom.DOMException {}

private Element newElement(Document doc, String name, String value) {}

private PartsFacadeHome getPartsFacadeHome() throws Exception {}

private DocumentBuilder getDocumentBuilder() throws Exception {}

}
