Hi,

I am having a problem in order to pass parameters to a method in the client, this is my code:

public Object GetSerialNumbers(UUID messageID, UUID correlationID, String initiatorID, String partnerID, //————————–Here I receive all parameters fine
String[][] extensionParametersStr, String requestedQuantityStr, String outputFormatStr, String poolID,
String gTIN, String sSCCGCP, String sSCCExtension, String germanyIFA, String franceCIP,
String spainNationalCode, String aNVISARegistryNumber, String location, String subLocation,
String lotNumber) {

KeyValuePairDataType[] extensionParameters = new KeyValuePairDataType[extensionParametersStr.length];
for (int i = 0; i < extensionParametersStr.length; i++) {
String[] parameter = extensionParametersStr[i];
Object var = new Object();
var = parameter[1];
extensionParameters[i] = new KeyValuePairDataType(parameter[0], var); //———————–Here I convert the data into KeyValuePairDataType
}

System.out.println("Extension Parameters en el cliente 1= " + extensionParameters[0].getKey() + ": " // ——————————— Print the data OK
+ extensionParameters[0].getValue());
System.out.println("Extension Parameters en el cliente 2= " + extensionParameters[1].getKey() + ": "
+ extensionParameters[1].getValue());
System.out.println("Extension Parameters en el cliente 1= " + extensionParameters[2].getKey() + ": "
+ extensionParameters[2].getValue());
System.out.println("Extension Parameters en el cliente 2= " + extensionParameters[3].getKey() + ": "
+ extensionParameters[3].getValue());

UnsignedInteger requestedQuantity = new UnsignedInteger(requestedQuantityStr);

SIDFormatEnum outputFormat = (outputFormatStr.compareToIgnoreCase("serialonly") == 0) ? SIDFormatEnum.SERIALONLY
: SIDFormatEnum.SERIALONLY;

HeaderDataType headerInput = new HeaderDataType(messageID, correlationID, initiatorID, partnerID,
extensionParameters);
PoolSelectorDataType poolSelector = new PoolSelectorDataType(poolID, gTIN, sSCCGCP, sSCCExtension, germanyIFA,
franceCIP, spainNationalCode, aNVISARegistryNumber, location, subLocation, lotNumber,
extensionParameters);
GetSerialNumbersInputDataType bodyInput = new GetSerialNumbersInputDataType(requestedQuantity, poolSelector,
outputFormat);

return GetSerialNumbers(headerInput, bodyInput);
}

//——————————- GetSerialNumbers——————————————————-
public Object GetSerialNumbers(HeaderDataType headerInput, GetSerialNumbersInputDataType bodyInput) {

client.registerModel(ClientInformationModel.MODEL);

SerialNumbersManagerTypeImpl serialNumbersManager = new SerialNumbersManagerTypeImpl(new AddressSpace(client),
new NodeId(2, 44), new QualifiedName(2, "SerialNumbersManager"),
new LocalizedText("SerialNumbersManager"));
GetSerialNumbersMethodOutputs outputs;
try {
outputs = serialNumbersManager.getSerialNumbers(headerInput, bodyInput); //————Here call the method getSerialNumbers with the parameters OK

Hashtable resultTable = new Hashtable();
resultTable.put(“MessageID”, outputs.getHeaderOutput().getMessageID());
resultTable.put(“CorrelationID”, outputs.getHeaderOutput().getCorrelationID());
resultTable.put(“PoolID”, outputs.getBodyOutput().getPoolID());
resultTable.put(“OutputFormat”, outputs.getBodyOutput().getOutputFormat().toString());
resultTable.put(“RequestToken”, outputs.getBodyOutput().getRequestToken().toString());
resultTable.put(“ReturnedQuantity”, outputs.getBodyOutput().getReturnedQuantity().toString());
resultTable.put(“SerialNumbers”, outputs.getBodyOutput().getSerialNumbers());
resultTable.put(“FirstSerial”, outputs.getBodyOutput().getFirstSerial());
resultTable.put(“LastSerial”, outputs.getBodyOutput().getLastSerial());
resultTable.put(“MessageID”, outputs.getFunctionalResult().toString());

System.out.println(Arrays.toString(outputs.getBodyOutput().getSerialNumbers()));

return resultTable;

} catch (MethodCallStatusException | ServiceException e) {
e.printStackTrace();
}
return null;
}

//——————————————getSerialNumbers——————————————
@Override
public SerialNumbersManagerType.GetSerialNumbersMethodOutputs getSerialNumbers(HeaderDataType headerInput,
GetSerialNumbersInputDataType bodyInput) throws MethodCallStatusException, ServiceException {

KeyValuePairDataType[] extensionParameters = headerInput.getExtensionParameters(); // ———————– Here I receive the parameters OK
System.out.println(“Extensions= ” + extensionParameters[0].getKey() + “: ” + extensionParameters[0].getValue()); // ——————- Print the parameters OK
System.out.println(“Extensions= ” + extensionParameters[1].getKey() + “: ” + extensionParameters[1].getValue());
System.out.println(“Extensions= ” + extensionParameters[2].getKey() + “: ” + extensionParameters[2].getValue());
System.out.println(“Extensions= ” + extensionParameters[3].getKey() + “: ” + extensionParameters[3].getValue());

NodeId methodId = new NodeId(2, 45);

return call(methodId, new MethodArgumentTransformer() { // —- In this line is the error!!!
@Override
public SerialNumbersManagerType.GetSerialNumbersMethodOutputs fromVariantArray(Variant[] values) {
return new SerialNumbersManagerType.GetSerialNumbersMethodOutputs((HeaderDataType) values[0].getValue(),
(GetSerialNumbersOutputDataType) values[1].getValue(),
(FunctionalResultEnum) values[2].asEnum(FunctionalResultEnum.class));
}
}, (Object) headerInput, (Object) bodyInput);
}

And this is the error: ServiceResult=Bad_EncodingError (0x80060000) “Encoding halted because of invalid data in the objects being serialized.”

I do not know how do I have to send the values in the headerInput, to catch all the extensionParameters on my OPCUA Server.

Thank you!
