Every once in a while Paypal is returning a 500 error code to my .net applications ipn script. It is returning that code in the response to the verification request
Here's the error that is logged:
System.Net.WebException
The remote server returned an error: (500) Internal Server Error.
System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.Net.WebException: The remote server returned an error: (500) Internal Server Error.
at System.Net.HttpWebRequest.GetResponse()
at ASP.ipn_aspx.Page_Load(Object sender, EventArgs e)
The code that Im using for the call is:
endPoint = "https://www.paypal.com/cgi-bin/webscr";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(endPoint);
//Set values for the request back
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
byte[] param = Request.BinaryRead(HttpContext.Current.Request.ContentLength);
string strRequest = Encoding.ASCII.GetString(param);
strRequest += "&cmd=_notify-validate";
req.ContentLength = strRequest.Length;
//Send the request to PayPal and get the response
StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();
This probably happens about once per day and PayPal doesn't retry the ipn message. The other 95% of the PayPal ipn transactions are working fine. Any ideas?

We defined email workflow in power automate for sending micro soft’s teams meeting invite, and we tried to send using spring-boot RestTemplate.
However, we are getting error saying “401 Unauthorized: [no body]”.
Here is what we tried in sending teams invitation using RestTemplate
RestTemplate restTemplate = new RestTemplate(clientHttpRequestFactory);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
MultiValueMap<String, String> data = new LinkedMultiValueMap<>();
data.add("SUBJECT", "xxx");
data.add("START_TIME", "xxx");
data.add("END_TIME", "xxx");
data.add("ATTENDEES", "xxx");
data.add("TEXT_BODY", "xxx");
HttpEntity<MultiValueMap> entity = new HttpEntity<>(data, headers);
ResponseEntity<String> response = restTemplate.postForEntity(url, entity, String.class);
While the same workflow is working sending teams meeting using OKHttp with below code snippet,
OkHttpClient client = new OkHttpClient();
MediaType mediaType = MediaType.parse("application/json");
RequestBody body = RequestBody.create(mediaType, "json formatted string content");
Request request = new Request.Builder().url(<<workflow-url>>).method("POST", body).addHeader("Content-Type", "application/json").build();
Response response = client.newCall(request).execute();
There is no authentication/authorization details are provided while sending teams meeting request using OkHttp.
Any clue, where we are going wrong?
I have an apache camel application that requires sending log files to an endpoint and this requires Basic Authentication. I was able to pass the authMethod, authusername and authPassword to the url as specified in the camel documentation but the challange I'm having is that I keep getting null response from the endpoint after starting the application.
However, the same endpoint returns response code and response body using postman.
Below is my code:
from("{{routes.feeds.working.directory}}?idempotent=true")
.process(new Processor() {
#Override
public void process(Exchange exchange) throws Exception {
MultipartEntityBuilder multipartEntityBuilder = MultipartEntityBuilder.create();
multipartEntityBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
String fileName = exchange.getIn().getHeader(Exchange.FILE_NAME, String.class);
File file = exchange.getIn().getBody(File.class);
multipartEntityBuilder.addPart("file",
new FileBody(file, ContentType.MULTIPART_FORM_DATA, fileName));
exchange.getOut().setBody(multipartEntityBuilder.build());
Message out = exchange.getOut();
int responseCode = out.getHeader(Exchange.HTTP_RESPONSE_CODE, Integer.class);
log.info("response code "+responseCode);
}
})
.setHeader(Exchange.HTTP_QUERY,
constant("authMethod=Basic&authUsername="+username+"&authPassword="+password+""))
.to(TARGET_WITH_AUTH +"/"+uuid+"/files")
.log(LoggingLevel.DEBUG, "response code >>>>"+Exchange.HTTP_RESPONSE_CODE)
.log(LoggingLevel.INFO, "RESPONSE BODY ${body}")
.end();
Kindly help review and advise further
For HTTP basic authentication I use this before sending a request
<setHeader headerName="Authorization">
<constant>Basic cm9vdDpyb290</constant>
</setHeader>
cm9vdDpyb290 - Encoded Base64 root:root(username and password) string
This was fixed by using httpClient to send my requests with Basic Authentication. Apparently, authMethod in apache camel doesn't send the credentials along with the Post Request and that's why I was getting the initial 401 response code.
Thank y'all for your contributions.
I created a mock service in SoapUI. I am using Groovy in this mock service so I can mock some requests, as well as forward other requests to the actual web service I am mocking.
When the web service returns one of three possible fault messages, I am unable to retrieve that actual fault from the soap response.
The mock service Groovy script just replies with the response herebelow (IOException, http status 500).
But when sending a request to the actual web service directly, I get the response I actually would like to get.
Groovy code which forwards the request and retrieve a response:
def soapUrl = new URL("[actual web service]");
def connection = soapUrl.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type" ,"text/html");
connection.setRequestProperty("SOAPAction", "");
connection.doOutput = true;
Writer writer = new OutputStreamWriter(connection.outputStream);
writer.write(soapRequest);
writer.flush();
writer.close();
connection.connect();
def soapResponse = connection.content.text;
// alert.showInfoMessage(soapResponse);
requestContext.responseMessage = soapResponse;
Response using the Groovy scripted mock service:
<soapenv:Body>
<soapenv:Fault>
<faultcode>Server</faultcode>
<faultstring>Failed to dispatch using script; java.io.IOException: Server returned HTTP response code: 500 for URL: [the endpoint url]</faultstring>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
Response when accessing the web service directly (with the same request):
<soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Server</faultcode>
<faultstring> [actual fault message] </faultstring>
<detail> [useful details about the fault] </detail>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
When using the script, why is the response not the same as if I would retrieve it directly?
Ok I found out I can use the connection (URLConnection) in a different way.
I made some changes based on the accepted answer here.
Now, the actual response, happy or error, is retrieved. So in both cases the web service response is being forwarded to the mock service output. And now I can see the fault info in the response.
...
connection.connect();
// Get the response
HttpURLConnection httpConnection = (HttpURLConnection) connection;
InputStream is;
if (httpConnection.getResponseCode() < HttpURLConnection.HTTP_BAD_REQUEST) {
is = httpConnection.getInputStream();
} else {
// Http error
is = httpConnection.getErrorStream();
}
// Read from input stream
StringBuilder builder = new StringBuilder();
BufferedReader buffer = new BufferedReader(new InputStreamReader(is));
String line;
while ((line = buffer.readLine()) != null) {
builder.append(line);
}
buffer.close();
// Forward the response to mock service output
requestContext.responseMessage = builder.toString();
I am using RestEasy client api, to make call to some internal api, but when I run the code from my home I am able to get the response without any timeout exception. But when I run from office getting timeout execution, am I missing any configurations?
I/O exception (java.net.ConnectException) caught when processing request: Operation timed out
Below the code am using:
ClientRequest request = new ClientRequest(
"https://example.com/v2");
request.queryParameter("name", "jhon");
request.accept("application/json");
ClientResponse<String> response = request.get(String.class);
if(response.getStatus() == 404){
System.out.println(response.getEntity());
System.out.println(response.getStatus());
}
BufferedReader br = new BufferedReader(new InputStreamReader(
new ByteArrayInputStream(response.getEntity().getBytes())));
String output;
System.out.println("Output from Server .... \n");
while ((output = br.readLine()) != null) {
System.out.println(output);
JSONObject d = new JSONObject(output);
JSONObject sd = d.getJSONObject("Error");
System.out.println(sd.get("Detail"));
}
I have a method that sends many emails to exchange server over smtp using JavaMail, below is my code,
public void sendMail(){
final String host="host",port="587",username="mail1#local.local",password="password",from="";
try {
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.port", port);
props.put("mail.smtp.ssl.trust", host);
final String email = from;
Authenticator authenticator = new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
};
Session session = Session.getInstance(props,authenticator);
InternetAddress replyToAddress [] = new InternetAddress[1];
replyToAddress[0] = new InternetAddress("mail1#local.local");
Transport transport = session.getTransport("smtp");
MimeMessage mimeMessage = new MimeMessage(session);
mimeMessage.setFrom(new InternetAddress("mail1#local.local"));
mimeMessage.addRecipient(Message.RecipientType.TO, new InternetAddress("mail2#local.local"));
mimeMessage.setSubject("Test");
mimeMessage.setText("Hello Testing");
mimeMessage.setReplyTo(replyToAddress);
transport.send(mimeMessage);
System.out.println("Email has been Sent Successfully to");
} catch (MessagingException e) {
e.printStackTrace();
}
Now when I apply a loop and call this function 10 times then only first five emails are sent successfully, for rest of the request I get the following exception,
javax.mail.MessagingException: Can't send command to SMTP host;
nested exception is:
java.net.SocketException: Connection closed by remote host
at com.sun.mail.smtp.SMTPTransport.sendCommand(SMTPTransport.java:2157)
at com.sun.mail.smtp.SMTPTransport.sendCommand(SMTPTransport.java:2144)
at com.sun.mail.smtp.SMTPTransport.close(SMTPTransport.java:1210)
at javax.mail.Transport.send0(Transport.java:197)
at javax.mail.Transport.send(Transport.java:124)
if I increase the request count then still only first five emails are sent, rest of them throws the exception.
If I put the failed request in some queue and retry them later then some of them will be sent.
Any clue will be appreciated, do I need to check for some configuration on Exchange server?
We have seen this exact same issue with a MS Exchange Server 2010. We had to increase the ReceiveConnector message rate limit by issuing the following Powershell-command:
Set-ReceiveConnector "Client CLIENTNAME" -MessageRateLimit unlimited
