Searched quite a bit. The problem with these errors is that while the text might appear the same, the problem is always different.
My service takes ONE string value and returns a string response. Here is my code:
private class UploadStats extends AsyncTask<String, Void, String>
{
private static final String WSDL_TARGET_NAMESPACE = "http://tempuri.org/";
private static final String SOAP_ADDRESS = "http://192.168.1.101/rss/RSS_Service.asmx?WSDL";
private static final String INSERTURLACTION = "http://192.168.1.101/rss/RSS_Service.asmx/InsertURL";
private static final String INSERTURLMETHOD = "InsertURL";
#Override
protected String doInBackground(String... url)
{
String status = "";
SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,
INSERTURLMETHOD);
request.addProperty("url", "www.yahoo.com");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);
try
{
httpTransport.call(INSERTURLACTION, envelope);
SoapObject response = (SoapObject) envelope.bodyIn;
status = response.getProperty(0).toString();
}
catch (Exception exception)
{
Log.d("Error", exception.toString());
}
if(status.equals("1"))
{
Log.d("InsertURL", "New URL Inserterd");
}
else if(status.equals("0"))
{
Log.d("InsertURL", "URL Exists. Count incremented");
}
else
{
Log.d("InsertURL", "Err... No");
}
return status;
}
}
I get the error:
java.lang.classcastexception org.ksoap2.SoapFault
What am I doing wrong? If any more details are needed, I can add them.
The error was related to the webservice.
An incorrect namespace on the service side can cause this error (as can a lot of other problems).
Best way to check is to run the webservice on the local machine (where the service is hosted).

I am trying to use aws sdk2 java for s3 select operations but not able to get extract the final data. Looking for an example if someone has implemented it. I got some idea from [this post][1] but not able to figure out how to get and read the full data .
Fetching specific fields from an S3 document
Basically, equivalent of v1 sdk:
``` InputStream resultInputStream = result.getPayload().getRecordsInputStream(
new SelectObjectContentEventVisitor() {
#Override
public void visit(SelectObjectContentEvent.StatsEvent event)
{
System.out.println(
"Received Stats, Bytes Scanned: " + event.getDetails().getBytesScanned()
+ " Bytes Processed: " + event.getDetails().getBytesProcessed());
}
/*
* An End Event informs that the request has finished successfully.
*/
#Override
public void visit(SelectObjectContentEvent.EndEvent event)
{
isResultComplete.set(true);
System.out.println("Received End Event. Result is complete.");
}
}
);```
///IN AWS SDK2, how do get ResultOutputStream ?

i came to your post since I was working on the same issue as to avoid V1.
After hours of searching i ended up with finding the answer at. https://github.com/aws/aws-sdk-java-v2/pull/2943/files
The answer is located at SelectObjectContentIntegrationTest.java File
services/s3/src/it/java/software/amazon/awssdk/services/SelectObjectContentIntegrationTest.java
The way to get the bytes is by using the RecordsEvent class, please note for my use case I used CSV, not sure if this would be different for a different file type.
in the complete method you have access to the receivedEvents. this is where you get the first index to get the filtered returned results and casting it to the RecordsEvent class. then this class provides the payload as bytes
#Override
public void complete() {
RecordsEvent records = (RecordsEvent) this.receivedEvents.get(0)
String result = records.payload().asUtf8String();
}
I have a pre-request script that I gathered from another post on StackOverflow, but I'm still getting invalid credentials.
Attempted to do this just with str_1 but it's not working. Not sure what request.data is supposed to do as it keeps returning NaN. I think that the problem might be there, but still at a loss. I've attempted converting all variables to a string, but that still returned the same error.
URL = https://gateway.marvel.com/v1/public/characters?ts={{timeStamp}}&apikey={{apiKey}}&hash={{hash}}
// Access your env variables like this
var ts = new Date();
ts = ts.getUTCMilliseconds();
var str_1 = ts + environment.apiKey + environment.privateKey;
// Or get your request parameters
var str_2 = request.data["timeStamp"] + request.data["apiKey"];
console.log('str_2 = ' + str_2);
// Use the CryptoJS
var hash = CryptoJS.MD5(str_1).toString();
// Set the new environment variable
pm.environment.set('timeStamp', ts);
pm.environment.set('hash', hash);
{
"code": "InvalidCredentials",
"message": "That hash, timestamp and key combination is invalid."
}
If someone can comment on why this is the solution, I would appreciate it. Here is what the issue was. The order of the hash actually matters. So had to flip the order of pvtkey + pubkey to pubkey + pvtkey. Why is this?
INCORRECT
var message = ts+pubkey+pvtkey;
var a = CryptoJS.MD5(message);
pm.environment.set("hash", a.toString());
CORRECT
var message = ts+pvtkey+pubkey;
var a = CryptoJS.MD5(message);
pm.environment.set("hash", a.toString());
I created in Android Studio, a new java class named MD5Hash, following the steps of https://javarevisited.blogspot.com/2013/03/generate-md5-hash-in-java-string-byte-array-example-tutorial.html
I just simplified his (her) code, only to use it with Java utility MessageDigest
public class MD5Hash {
public static void main(String args[]) {
String publickey = "abcdef"; //your api key
String privatekey = "123456"; //your private key
Calendar calendar=Calendar.getInstance();
String stringToHash = calendar
.getTimeInMillis()+ privatekey + publickey;
System.out.println("hash : " + md5Java(stringToHash));
System.out.println("ts : "+ calendar.getTimeInMillis());
}
public static String md5Java(String message){
String digest = null;
try {
MessageDigest md = MessageDigest.getInstance("MD5");
byte[] hash = md.digest(message.getBytes("UTF-8"));
//converting byte array to Hexadecimal String
StringBuilder sb = new StringBuilder(2*hash.length);
for(byte b : hash){
sb.append(String.format("%02x", b&0xff));
}
digest = sb.toString();
} catch (UnsupportedEncodingException ex) {
} catch (NoSuchAlgorithmException ex) {
}
return digest;
}
}
As you can see, if you copy paste this code, it has a green arrow on the left side of the class declaration, clicking it you can run MD5Hash.main() and you'll have printed in your Run Screen the values for the time (ts) and for the hash.
Then go to verify directly into the internet :

I am facing strange issue where response as string not coming back from one service to another service. we have created microservices where one service is calling another service. i can see response printed in logs . after that line immediately i am returning that response but its coming back as null.
I created similar method with same code and it works fine. I have put code for calling service and service method from which i am returning response.
controller:
#RequestMapping(value = "/test/save", method = RequestMethod.POST)
#ResponseBody
public String save(#RequestBody Calculation calculation,
HttpServletRequest request) {
logger.info("In .save");
String result = "false";
try {
result = CalService.save(calculation);
logger.info("Response from service is :" + result);
} catch (Exception e) {
logger.error("Exception occured in save:", e);
}
return result;
}
method call client :
public String saveCal(Calculation calculation) {
String result = null;
try {
logger.info("In save");
MultiValueMap<String, String> headers = new LinkedMultiValueMap<String, String>();
headers.add("REMOTE_USER", "test");
HttpEntity<Calculation> request = new HttpEntity<Calculation>(Calculation, headers);
RestTemplate template = new RestTemplate();
template.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
result = template.postForObject(url+"/test/save", request, String.class);
} catch (Exception e) {
logger.error("Exception occured in SaveMddMd", e);
result = "fail";
}
logger.info("Save"+result);
return result;
}
result returned is success or failure.
I can see result printed in controller as success but when it comes back to client it prints as null. I created exact same method with different signature which returns result as success. we are using microservices here.

I am trying to send a string to the EventHub and I have written this code:
private static void sendPOST(ValueChangeMessage valueChangeMessage) throws IOException {
try {
// final String namespaceName = ""; //sericebusnamespacename
// final String eventHubName = "";
// final String sasKeyName = "";
// final String sasKey = "";
// ConnectionStringBuilder connStr = new ConnectionStringBuilder(namespaceName, eventHubName, sasKeyName, sasKey);
byte[] payloadBytes = valueChangeMessage.data.get().toString().getBytes(StandardCharsets.UTF_8);
EventData sendEvent = new EventData(payloadBytes);
EventHubClient ehClient = EventHubClient.createFromConnectionStringSync(connStr.toString());
ehClient.sendSync(sendEvent);
}
catch (ServiceBusException ex) {
Logger.getLogger(CatChannel.class.getName()).log(Level.SEVERE, null, ex);
}
}
But whenever I try to run the project from netbeans , it
gives the error below:
error: cannot access Message
sendEvent = new EventData(payloadBytes);
class file for org.apache.qpid.proton.message.Message not found
Can anyone tell me what can be the possible issue??
I got the fix for this..........actually the issue was with the proxies of the system.....it wasnt able to download the jars from maven.....So i manually included the dependencies in my project
We've created a custom webservice in Umbraco to add (async) files and upload them. After upload the service is called with node and file-information to add a new node to the content tree.
At first our main problem was that the service was running outside of the Umbraco context, giving strange errors with get_currentuser.
Now, we inherit the umbraco BaseWebService from the umbraco.webservices dll and we've set all acces information in the settings file; we authenticatie before doing anything else using (correct and ugly-hardcoded) administrator.
When we now execute the webservice (from the browser or anything else) we get:
at umbraco.DataLayer.SqlHelper`1.ExecuteReader(String commandText, IParameter[] parameters)
at umbraco.cms.businesslogic.CMSNode.setupNode()
at umbraco.cms.businesslogic.web.Document.setupNode()
at umbraco.cms.businesslogic.CMSNode..ctor(Int32 Id)
at umbraco.cms.businesslogic.Content..ctor(Int32 id)
at umbraco.cms.businesslogic.web.Document..ctor(Int32 id)
at FileUpload.AddDocument(String ProjectID, String NodeID, String FileName)*
Where AddDocument is our method. The node (filename w/o extension) does not exist in the tree (not anywhere, it's a new filename/node). We've cleared the recycle bin, so it's not in there either.
Are we missing something vital, does anyone has a solution?
Below is the source for the webservice;
using umbraco.cms.businesslogic.web;
using umbraco.BusinessLogic;
using umbraco.presentation.nodeFactory;
using umbraco.cms.businesslogic.member;
using umbraco.cms;

We've rewritten the whole procedure (dumped all code and restart) and we've got it working now.
I think we've been messing around with the old code so much in trying to get it to work we were missing some key issues, because it functions.
Thanks for thinking along anyway!
