I am new to OpenTelemetry word. I have created spans for my services separately, but when i am try to combine spans of two different services, using context propogation, I am not able to do it successfully.
I have used following code:
// at client side:
public static void sendContext(String resource) {
TextMapSetter<HttpURLConnection> setter =
new TextMapSetter<HttpURLConnection>() {
#Override
public void set(HttpURLConnection carrier, String key, String value) {
carrier.setRequestProperty(key, value);
}
};
HttpURLConnection transportLayer = null;
String urlString = "http://127.0.0.1:8080" + resource;
try {
URL url = new URL(urlString);
transportLayer = (HttpURLConnection) url.openConnection();
} catch (MalformedURLException ex) {
System.out.println(ex.getMessage());
} catch (IOException e) {
System.out.println(e.getMessage());
}
GlobalOpenTelemetry.getPropagators()
.getTextMapPropagator()
.inject(Context.current(), transportLayer, setter);
}
// at server side:
public static Context getContext(HttpServletRequest request) {
TextMapGetter<HttpServletRequest> getter =
new TextMapGetter<HttpServletRequest>() {
#Override
public String get(HttpServletRequest carrier, String key) {
Enumeration<String> headerNames = carrier.getHeaderNames();
if (headerNames != null) {
while (headerNames.hasMoreElements()) {
String headerName = headerNames.nextElement();
System.out.println("headerNames.nextElement(): " + headerName);
if (headerName.equals(key)) {
String headerValue = request.getHeader(headerName);
System.out.println("headerValue): " + headerValue);
return headerValue;
}
}
}
return null;
}
#Override
public Iterable<String> keys(HttpServletRequest carrier) {
Set<String> set = new HashSet<String>();
Enumeration<String> headerNames = carrier.getHeaderNames();
if (headerNames != null) {
while (headerNames.hasMoreElements()) {
set.add(headerNames.nextElement());
}
}
return set;
}
};
Context extractedContext =
GlobalOpenTelemetry.getPropagators()
.getTextMapPropagator()
.extract(Context.current(), request, getter);
At server, i am not able to get parent span.
Kindly help on this.
You can refer to OpenTelemetry main documentation from here. It contains the context propagation part but I used HttpHeader type getter as the TextMapGetter with the same functionality which shows in the doc and instead of using
Scope scope = extractedContext.makeCurrent()
as the scope to create a child span, better to use directly without the scope,
tracer.spanBuilder(spanName).setParent(extractedContext)
Because sometimes the automated way to propagate the parent span on the current thread does not work fine.
I want to use Java PayPal SDK to get account history. I tried this simple code:
public void randomDatabaseData() throws SQLException, FileNotFoundException, IOException, PayPalRESTException {
String clientID = "test";
String clientSecret = "test";
String accessToken = null;
try {
Map<String, String> map = new HashMap<String, String>();
map.put("mode", "live");
try {
accessToken = new OAuthTokenCredential(clientID, clientSecret, map).getAccessToken();
} catch (Exception e) {
e.printStackTrace();
}
System.out.println(accessToken);
transactionSearch(accessToken);
} catch (Exception e) {
e.printStackTrace();
}
}
public TransactionSearchResponseType transactionSearch(String accessToken) {
TransactionSearchReq transactionSearchReq = new TransactionSearchReq();
TransactionSearchRequestType transactionSearchRequest = new TransactionSearchRequestType(
"2012-12-25T00:00:00+0530");
transactionSearchReq.setTransactionSearchRequest(transactionSearchRequest);
PayPalAPIInterfaceServiceService service = new PayPalAPIInterfaceServiceService();
service.setTokenSecret(accessToken);
TransactionSearchResponseType transactionSearchResponse = null;
try {
transactionSearchResponse = service.transactionSearch(transactionSearchReq);
} catch (Exception e) {
System.out.println("Error Message : " + e.getMessage());
}
if (transactionSearchResponse.getAck().getValue().equalsIgnoreCase("success")) {
Iterator<PaymentTransactionSearchResultType> iterator = transactionSearchResponse
.getPaymentTransactions().iterator();
while (iterator.hasNext()) {
PaymentTransactionSearchResultType searchResult = iterator.next();
System.out.println("Transaction ID : " + searchResult.getTransactionID());
}
} else {
List<ErrorType> errorList = transactionSearchResponse.getErrors();
System.out.println("API Error Message : " + errorList.get(0).getLongMessage());
}
return transactionSearchResponse;
}
But I get his error stack when I run the code:
Error Message : configurationMap cannot be null
java.lang.NullPointerException
at com.crm.web.tickets.GenearateTicketsTest.transactionSearch(GenearateTicketsTest.java:161)
at com.crm.web.tickets.GenearateTicketsTest.randomDatabaseData(GenearateTicketsTest.java:139)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)
How I can fix this code? I configure client ID and secret key into PayPal web site but still I get error.
I recommend you using TransactionSearch API to get the payment history based on your search date range.
I have using Google (GDATA) Gmail API for retrieving the contact list from gmail, It is working successfully on windows environment, but when I run the same code on Linux, I get error of Invalid Credentials.

I am trying to get the absolute URL in my managed bean's action listener. I have used:
HttpServletRequest#getRequestURL() // returning http://localhost:7101/POSM/pages/catalog-edit
HttpServetRequest#getQueryString() // returning _adf.ctrl-state=gfjk46nd7_9
But the actual URL is: http://localhost:7101/POSM/pages/catalog-edit?_adf.ctrl-state=gfjk46nd7_9&articleReference=HEN00067&_afrLoop=343543687406787. I don't know why the parameter artcileReference get omitted.
Is there any method which can give me the whole URL at once? How can I get the whole URL with all query string?
You can reconstruct your URL manually by using ServletRequest#getParameterNames() and ServletRequest#getParameter() both available with the HttpServletRequest instance.
Here is a sample code I've used in the past for this exact purpose :
private String getURL()
{
Enumeration<String> lParameters;
String sParameter;
StringBuilder sbURL = new StringBuilder();
Object oRequest = FacesContext.getCurrentInstance().getExternalContext().getRequest();
try
{
if(oRequest instanceof HttpServletRequest)
{
sbURL.append(((HttpServletRequest)oRequest).getRequestURL().toString());
lParameters = ((HttpServletRequest)oRequest).getParameterNames();
if(lParameters.hasMoreElements())
{
if(!sbURL.toString().contains("?"))
{
sbURL.append("?");
}
else
{
sbURL.append("&");
}
}
while(lParameters.hasMoreElements())
{
sParameter = lParameters.nextElement();
sbURL.append(sParameter);
sbURL.append("=");
sbURL.append(URLEncoder.encode(((HttpServletRequest)oRequest).getParameter(sParameter),"UTF-8"));
if(lParameters.hasMoreElements())
{
sbURL.append("&");
}
}
}
}
catch(Exception e)
{
// Do nothing
}
return sbURL.toString();
}
Here I came up with my solution, taking idea of the answer given by Alexandre, considering that HttpServletRequest#getParameterValues() method:
protected String getCurrentURL() throws UnsupportedEncodingException {
Enumeration parameters = getServletRequest().getParameterNames();
StringBuffer urlBuffer = new StringBuffer();
urlBuffer.append(getServletRequest().getRequestURL().toString());
if(parameters.hasMoreElements()) {
if(!urlBuffer.toString().contains("?")) {
urlBuffer.append("?");
} else {
urlBuffer.append("&");
}
}
while(parameters.hasMoreElements()) {
String parameter = (String)parameters.nextElement();
String[] parameterValues = getServletRequest().getParameterValues(parameter);
if(!CollectionUtils.sizeIsEmpty(parameterValues)) {
for(int i = 0; i < parameterValues.length; i++) {
String value = parameterValues[i];
if(StringUtils.isNotBlank(value)) {
urlBuffer.append(parameter);
urlBuffer.append("=");
urlBuffer.append(URLEncoder.encode(value, "UTF-8"));
if((i + 1) != parameterValues.length) {
urlBuffer.append("&");
}
}
}
}
if(parameters.hasMoreElements()) {
urlBuffer.append("&");
}
}
return urlBuffer.toString();
}
I'm developing (trying for now) portlet that will be integrated with LinkedIn.
Following the documentation about it:
http://developer.linkedin.com/docs/DOC-1008 -->
The first step to authorizing a LinkedIn member is requesting a requestToken. This request is done with an HTTP POST.
For the requestToken step, the following components should be present in your string to sign:
* HTTP Method (POST)
* Request URI (https://api.linkedin.com/uas/oauth/requestToken)
* oauth_callback
* oauth_consumer_key
* oauth_nonce
* oauth_signature_method
* oauth_timestamp
* oauth_version
I have already API(it's oauth_consumer_key) key and i need to generate specific URL string.
Have next java code for this URL and HTTP connection:
private void processAuthentication() {
Calendar cal = Calendar.getInstance();
Long ms = cal.getTimeInMillis();
Long timestamp = ms / 1000;
Random r = new Random();
Long nonce = r.nextLong();
String prefixUrl = "https://api.linkedin.com/uas/oauth/requestToken";
String oauthCallback = "oauth_callback=http://localhost/";
String oauthConsumerKey =
"&oauth_consumer_key=my_consumer_key";
String oauthNonce = "&oauth_nonce=" + nonce.toString();
String oauthSignatureMethod = "&oauth_signature_method=HMAC-SHA1";
String oauthTimestamp = "&oauth_timestamp=" + timestamp.toString();
String oauthVersion = "&oauth_version=1.0";
String mainUrl =
oauthCallback + oauthConsumerKey + oauthNonce + oauthSignatureMethod
+ oauthTimestamp + oauthVersion;
try {
prefixUrl =
URLEncoder.encode(prefixUrl, "UTF-8") + "&"
+ URLEncoder.encode(mainUrl, "UTF-8");
URL url = new URL(prefixUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
String msg = connection.getResponseMessage();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
The question is next,for those, who had faced this problem:
How should really look URL string for connection and how response is received?
For URL, it's interested the example of URL, you generated.
And for response interested, method to get it.
As i understand, after HTTP connection been established,that response is:
connection.getResponseMessage();
#sergionni I found answer to your Question from linkedin-developer
As you know
The first step to authorizing a Linked-In member is requesting a requestToken. This request is done with an HTTP POST.
Your base string should end up looking something like this if you're using a callback:
POST&https%3A%2F%2Fapi.linkedin.com%2Fuas%2Foauth%2FrequestToken
&oauth_callback%3Dhttp%253A%252F%252Flocalhost%252Foauth_callback%26o
auth_consumer_key%3DABCDEFGHIJKLMNOPQRSTUVWXYZ%26
oauth_nonce%3DoqwgSYFUD87MHmJJDv7bQqOF2EPnVus7Wkqj5duNByU%26
oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1259178158%26
oauth_version%3D1.0
You then sign this base string with your consumer_secret, computing a signature. In this case, if your secret was 1234567890, the signature would be TLQXuUzM7omwDbtXimn6bLDvfF8=.
Now you take the signature you generated, along with oauth_nonce, oauth_callback, oauth_signature_method, oauth_timestamp, oauth_consumer_key, and oauth_version and create an HTTP Authorization header. For this request, that HTTP header would look like:
Authorization: OAuth
oauth_nonce="oqwgSYFUD87MHmJJDv7bQqOF2EPnVus7Wkqj5duNByU",
oauth_callback="http%3A%2F%2Flocalhost%2Foauth_callback",
oauth_signature_method="HMAC-SHA1",
oauth_timestamp="1259178158",
oauth_consumer_key="ABCDEFGHIJKLMNOPQRSTUVWXYZ",
oauth_signature="TLQXuUzM7omwDbtXimn6bLDvfF8=",
oauth_version="1.0"
Please note, that the HTTP header is a single header -- not an HTTP header for each component. You can optionally supply a realm="http://api.linkedin.com".
As a response to your request for a requestToken, your requestToken will be in the "oauth_token" response field, a validation that we acknowledged your callback with the "oauth_callback_confirmed" field, an oauth_token_secret, and a oauth_expires_in, and a few other values.
(here us Your answaer) response would look like:
oauth_token=94ab03c4-ae2c-45e4-8732-0e6c4899db63
&oauth_token_secret=be6ccb24-bf0a-4ea8-a4b1-0a70508e452b
&oauth_callback_confirmed=true&oauth_expires_in=599
You might try out the OAuth libraries to handle the connection: http://code.google.com/p/oauth/
I created a plugin for Play Framework to easily integrated with LinkedIn's OAuth: geeks.aretotally.in/projects/play-framework-linkedin-module. Hopefully it can help. You should def check out Play, very very cool Java framework.
