Hi Gurus,
I'm having some troubles doing the mapping through java mapping in PI.
I've done the java class in the SAP NWDS and imported it on PI through the ESR.
Now i'm trying to test through the SOAP and i've found the following error in the "Communication Channel Monitor":
500 Internal Server Error SAP NetWeaver Application Server/Java AS
java.lang.NullPointerException: while trying to invoke the method com.sap.aii.af.sdk.xi.lang.Binary.getBytes() of a null object returned from com.sap.aii.af.sdk.xi.mo.xmb.XMBPayload.getContent()
And the following error in the SXMB_MONI:
<SAP:Category>XIServer</SAP:Category>
<SAP:Code area="INTERNAL">CLIENT_SEND_FAILED</SAP:Code>
<SAP:P1>500</SAP:P1>
<SAP:P2>Internal Server Error</SAP:P2>
<SAP:P3>(See attachment HTMLError for details)</SAP:P3>
<SAP:P4 />
<SAP:AdditionalText />
<SAP:Stack>Error while sending by HTTP (error code: 500 , error text: Internal Server Error) (See attachment HTMLError for details)</SAP:Stack>
I've developed the code below:
public class PI_Mapping_IF extends AbstractTransformation { public void transform(TransformationInput in, TransformationOutput out) throws StreamTransformationException { this.execute(in.getInputPayload().getInputStream(), out.getOutputPayload().getOutputStream()); } public void execute(InputStream in, OutputStream out) throws StreamTransformationException { try { // Inicio do java mapping getTrace().addInfo("JAVA Mapping Iniciado"); //Log para o PI/XI // Declarações referentes ao XML de entrada DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); Document xml_in = db.parse(in); // Declarações referentes ao XML de saída Document xml_out = db.newDocument(); TransformerFactory transformerFactory = TransformerFactory.newInstance(); Transformer transformer = transformerFactory.newTransformer(); // Remove o standalone xml_in.setXmlStandalone(true); // Declara a estrutura que a RFC irá receber Element root = xml_out.createElement("ns1:ZFSD_VMOI_UPLOAD_CF_PG"); root.setAttribute("xmlns:ns1","urn:sap-com:document:sap:rfc:functions"); xml_out.appendChild(root); Element i_cenario = xml_out.createElement("I_CENARIO"); root.appendChild(i_cenario); Element t_input = xml_out.createElement("T_INPUT"); root.appendChild(t_input); Element item = xml_out.createElement("ITEM"); t_input.appendChild(item); Element STRING = xml_out.createElement("STRING"); item.appendChild(STRING); Element t_return = xml_out.createElement("T_RETURN"); root.appendChild(t_return); Element item_r = xml_out.createElement("ITEM"); t_return.appendChild(item_r); Element message = xml_out.createElement("MESSAGE"); item_r.appendChild(message); // Verifica se existe algum filho no nó NodeList nodos = xml_in.getChildNodes(); if (nodos.item(0) != null) { getTrace().addInfo("O nó(XML) possui filhos"); //Log para o PI/XI // Declaração de variáveis String ident = ""; // <Ident> String buyer = ""; // <BuyerLineItemNum> String result = ""; // <Ident>;<BuyerLineItemNum>;<Date>;<QuantityValue> // Inicia a extração das informações do XML try{ // Recupera o nó ShipToParty NodeList nodeShip = xml_in.getElementsByTagName("ns0:ShipToParty"); Node node = nodeShip.item(0);

Element elemDt_Qnt = (Element)nodeDt_Qnt; NodeList nodeValores = elemDt_Qnt.getElementsByTagName("ns0:ScheduleDetail"); for (int j = 0; j < nodeValores.getLength(); j++) { node = nodeValores.item(j); elemXML = (Element) node; try{ // Preenche a chave Date NodeList modelExtra = elemXML.getElementsByTagName("ns0:Date"); Element extraElement = (Element) modelExtra.item(0); modelExtra = extraElement.getChildNodes();

} } // Marca o final do registro result += "||"; // Preenche os nós itens Text srcxml = xml_out.createTextNode(result); STRING.appendChild(srcxml); result = ""; buyer = ""; } }catch(Exception e){ } // Remove o standalone xml_out.setXmlStandalone(true);

throw new StreamTransformationException("Can not create DocumentBuilder.", e); } catch (SAXException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (TransformerConfigurationException e) { e.printStackTrace(); } catch (TransformerException e) { e.printStackTrace(); } }Am i doing anything wrong in the code? Where can this nullpointerexception be triggered?
Thanks.
