I cant seem to call this class from Android app to send sms via the sms APi i have attached.
I have attached my call to the sender class to make a call to the http class when i want to send an SMS on button click.
Button button;
button = (Button) findViewById(R.id.noBtn);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//createUserAppointment();
Sender sender = new Sender("xxxxxxxxxxxxx", 8080, "xxxxx",
"xxxx", "Congratulations! You just gave someone a priceless gift - LIFE! Thank you for donating." +
"Your next donation date is 13/6/16.", "1", "0", "xxxxxxxxx",
"Moja");
sender.submitMessage();
}
});
And what produces your attempt? An error? Or it compiles well but does'nt do anything? Please share any output too
Well you put "xxxxxxxxx" in args because you don't want us to see the real adress or because you are just copy pasting the example?
Otherwise I'd suggest you to take a look here

I want to discover all the destinations from solace (queues and topics)
I tried using MBeanServerConnection and query after names (but I didn't find a proper way to use this) or JNDI lookups Destination dest = (Destination) context.lookup(Dest_name), but I don't have the names of the queues/topics.
I am using solace - jms library.
I am searching for smth like this: (but for solace, not activeMq)
get all Queue from activeMQ
You will need to make use of SEMP over the management interface for this.
Sample commands:
curl -d '<rpc><show><queue><name>*</name></queue></show></rpc>' -u semp_username:semp_password http://your_management_ip:your_management_port/SEMP
curl -d '<rpc><show><topic-endpoint><name>*</name></topic-endpoint></show></rpc>' -u semp_username:semp_password http://your_management_ip:your_management_port/SEMP
Note that I'm using curl for simplicity, but any application can perform HTTP POSTs to execute these commands.
If you are using Java, you can refer to the SempHttpSetRequest sample found within the Solace API samples.
Documentation on SEMP can be found here.
However, the larger question here is why do you need to discover all destinations?
One of the features of the message broker is to decouple the publishers and consumers.
If you need to know if your persistent message is being published to a topic with no consumers, you can make use of the reject-msg-to-sender-on-no-subscription-match setting in the publishing application's client-profile.
This means that the publisher will obtain a negative acknowledgement in the event that it tries to publish a message on a topic that has no matching subscribers.
You can refer to "Handling Guaranteed Messages with No Matches" at https://docs.solace.com/Configuring-and-Managing/Configuring-Client-Profiles.htm for further details.
Here is some source code that might help. With the appliance configured correctly, SEMP is also available over JMS on topic "#SEMP/(router)/SHOW".

You can get message VPN specific queues and topics using following SEMPv2 command.
curl -s -X GET -u semp_user:semp_pass management_host:management_port/SEMP/v2/monitor/msgVpns/{vpn-name}/queues?select="queueName"
curl -s -X GET -u semp_user:semp_pass management_host:management_port/SEMP/v2/monitor/msgVpns/{vpn-name}/topicEndpoints?select="topicEndpointName"
I working with restFB for calling FaceBook Graph api to login, get posts and etc of users.
Created an app in developers account of Facebook.
Tried to call user details, with token generated here,
https://developers.facebook.com/tools/explorer?method=GET&path=8560751784547897&version=v2.8
For Example: accessToken from the above url provides = EAA....F
I am able to get all user details, when I am hitting url in browser as follows,
https://graph.facebook.com/v2.8/me?fields=id,name,email,birthday?access_token=EAA....f
I am getting following response in browser,
{
"id": "1127949",
"name": "youtr name",
"email": "youmail\u0040gmail.com"
"birthday": "10/27/1998"
}
I used following code to generate accesstoken dynamically,
StringBuffer callbackURLbuffer = request.getRequestURL();
int index = callbackURLbuffer.lastIndexOf("/");
callbackURLbuffer.replace(index, callbackURLbuffer.length(), "").append("/callback");
callbackURL = URLEncoder.encode(callbackURLbuffer.toString(), "UTF-8");
String authURL = "https://graph.facebook.com/oauth/authorize?client_id="
+ facebookAppId
+ "&redirect_uri="
+ callbackURL
+ "&scope=user_about_me,"
+ "user_actions.books,user_actions.fitness,user_actions.music,user_actions.news,user_actions.video,user_activities,user_birthday,user_education_history,"
+ "user_events,user_photos,user_friends,user_games_activity,user_groups,user_hometown,user_interests,user_likes,user_location,user_photos,user_relationship_details,"
+ "user_relationships,user_religion_politics,user_status,user_tagged_places,user_videos,user_website,user_work_history,ads_management,ads_read,email,"
+ "manage_notifications,manage_pages,publish_actions,read_friendlists,read_insights,read_mailbox,read_page_mailboxes,read_stream,rsvp_event";
In my callbackURL servlet, I am getting accessToken with code value, as follows,
StringBuffer redirectURLbuffer = request.getRequestURL();
int index = redirectURLbuffer.lastIndexOf("/");
redirectURLbuffer.replace(index, redirectURLbuffer.length(), "").append("/callback");
redirectURL = URLEncoder.encode(redirectURLbuffer.toString(), "UTF-8");
code = request.getParameter("code");
if(null!=code) {
accessURL = "https://graph.facebook.com/oauth/access_token?client_id=" + facebookAppId +
"&redirect_uri=" + redirectURL + "&client_secret=" + facebookAppSecret + "&code=" + code;
webContent = getWebContentFromURL(accessURL);
accessToken = getAccessTokenFromWebContent(webContent);
other functions used for this above code,
private static String getWebContentFromURL(String webnames) {
try {
URL url = new URL(webnames);
URLConnection urlc = url.openConnection();
//BufferedInputStream buffer = new BufferedInputStream(urlc.getInputStream());
BufferedReader buffer = new BufferedReader(new InputStreamReader(urlc.getInputStream(), "UTF8"));
StringBuffer builder = new StringBuffer();
int byteRead;
while ((byteRead = buffer.read()) != -1)
builder.append((char) byteRead);
buffer.close();
String text=builder.toString();
return text;
}
catch (IOException e) {
e.printStackTrace();
}
return null;
}
And,
private static String getAccessTokenFromWebContent (String webContent) {
String accessToken = null;
int s = webContent.indexOf("access_token=") + ("access_token=".length());
int e = webContent.indexOf("&");
accessToken = webContent.substring(s, e);
return accessToken;
}
Lets say this accessToken = EAA....2
If I call the below url with this Token,
https://graph.facebook.com/v2.8/me?fields=id,name,email,birthday&access_token=EAA....2
I am getting following response,
{
"id": "1127949",
"name": "youtr name",
"email": "youmail\u0040gmail.com"
}
If I hit following url, with bio feild, I got error msg in json as follows,
{
"error": {
"message": "(#12) bio field is deprecated for versions v2.8 and higher",
"type": "OAuthException",
"code": 12,
"fbtrace_id": "ARkoFJVP/Jk"
}
}
can some one say why this is happening for me.
Take a look here, to get about the user permission.
https://developers.facebook.com/docs/facebook-login/permissions/#reference-user_about_me.
As per your comment, regarding debuggin your token, sounds like you didn't get the permission enabled for user_about_me by facebook.
You have to send Facebook for a review about your app and need to approve by Facebook, then only you can access the user details and other things.
Follow these steps,
Go to - https://developers.facebook.com/apps/your_app_id/review-status/
Click on Start a submission button.
Select the check boxes,which you needs for permission. Then Click add Items button.
Then click on Edit Notes for each permission.
Here, breif about your app with this permission and upload a video of demo of your app.
Facebook will review it and accept/reject as per the norms.
This is what you are missing and it causes for your problem..
I'm working on gridsim project in Java eclipse. I have found a network flow program, which works only for one-to-one connection between the sender and receiver. If the same user (sender) wish to send a message to any other receiver, the program does not work. Similarly, if a receiver wish to send message to two sender users, it does not work. Here, I'm including all the java files for this work. In order to run the program, we need to include external .jar file path in the project.

After running these programs, someone can tell us how to extend the required functionality as I mentioned in the beginning.
Personal experience ... GridSim5.2 potentially buggy.
The examples are dated written for version < 4.0, demonstrating not very complex scenarios.
Using version 5.2. According to the API docs every simulation should have at least one TopRegionalRC. This appends a UniqueID to the filename and records the location of the file in two hashmaps one for filename and the other for fileattr. Now the event filename used for the lookup remains unchanged - the lookup fails - compares to the fileattrmap.name_. Consequently, the waiting for ack block is never executed when performing a addmaster operation.
Fix: Since the UniqueId is returned by the initial request to the CTLG this can be appended to the filename for the subsequent event requiring the lookup. Alternatively, add the filename to fileattrmap and the filename+uniqueid to fileattrmap, then test for both in the lookup.
Also, GridSimTags uses -1 to signal END_OF_SIMULATION, but this conflicts with Advanced Reservation (AR) block of tags. That also use negative numbers. GridSimTags has an optional routine to check for duplicates but its use is optional and does not apply to DataGridTags. I created a reversemap for ease of debugging adding validation to ensure no duplicates occur and deprecated the GridSimTags method.
I am now wrestling with the DataGrid user tasks that do not seem to create events, I am also concerned that the delay operations are not effective.
I am trying to upload video to vimeo and I understand that you need the ticket_id in order to be able to upload.
The think is I can not figure out how to get this ticket_id by using scribe.
Does anyone have any example how to do this?
Thanks in advance.
When I use:
OAuthRequest request = new OAuthRequest(Verb.GET, "http://vimeo.com/api/rest/v2");
request.addQuerystringParameter("method", "vimeo.videos.upload.getTicket");
this results in:
<err code="401" expl="The consumer key passed was not valid." msg="Invalid consumer key"/>
When I use method:
request.addQuerystringParameter("method", "vimeo.videos.upload.getQuota");
everything works fine. I tried putting some fake api key in the vimeo.videos.upload.getQuota method. That also resulted in invalid key. So it is not like method vimeo.videos.upload.getQuota does not need the api key. In fact it does and if you don't provide the valid key it wil not work. Somehow when calling method vimeo.videos.upload.getTicket, with the same api key that works for the mehod getQuota, I get response:
<err code="401" expl="The consumer key passed was not valid." msg="Invalid consumer key"/>
full code with fake api keys:
public class VimeoServiceConcept {
public static void main(String[] args) {
String apikey="api key";
String apisecret="secret";
String accessToken="access token";
String accessTokenSecret="access token secret";
OAuthService service = new ServiceBuilder()
.provider(VimeoApi.class)
.apiKey(apikey)
.apiSecret(apisecret)
.build();
Token token = new Token(accessToken, accessTokenSecret);
OAuthRequest request = new OAuthRequest(Verb.GET, "http://vimeo.com/api/rest/v2");
// request.addQuerystringParameter("method", "vimeo.videos.upload.getQuota");
request.addQuerystringParameter("format", "xml");
request.addQuerystringParameter("method", "vimeo.videos.upload.getTicket");
request.addQuerystringParameter("upload_method", "post");
service.signRequest(token, request);
System.out.println(request.getCompleteUrl());
Response response = request.send();
System.out.println("Got it! Lets see what we found...");
System.out.println(response.getHeader("code"));
System.out.println(response.getCode());
System.out.println(response.getBody());
}
}
Try getting the ticket after you get the quota. I have never tried getting the ticket without the quota first because their documentation explicitly states you need to check quota before you get the ticket. It looks like you just comment out what you're not testing. Try this instead:
public class VimeoServiceConcept {
public static void main(String[] args) {
String apikey="api key";
String apisecret="secret";
String accessToken="access token";
String accessTokenSecret="access token secret";
OAuthService service = new ServiceBuilder().provider(VimeoApi.class).apiKey(apiKey).apiSecret(apiSecret).build();
OAuthRequest request;
Response response;
accessToken = new Token("your_token", "your_tokens_secret");
accessToken = checkToken(vimeoAPIURL, accessToken, service);
if (accessToken == null) {
return;
}
// Get Quota
request = new OAuthRequest(Verb.GET, vimeoAPIURL);
request.addQuerystringParameter("method", "vimeo.videos.upload.getQuota");
signAndSendToVimeo(request, "getQuota", true);
// Get Ticket
request = new OAuthRequest(Verb.GET, vimeoAPIURL);
request.addQuerystringParameter("method", "vimeo.videos.upload.getTicket");
request.addQuerystringParameter("upload_method", "streaming");
response = signAndSendToVimeo(request, "getTicket", true);
//... the rest of your code...
}
}
Here's checkToken:
/**
* Checks the token to make sure it's still valid. If not, it pops up a dialog asking the user to
* authenticate.
*/
private static Token checkToken(String vimeoAPIURL, Token vimeoToken, OAuthService vimeoService) {
if (vimeoToken == null) {
vimeoToken = getNewToken(vimeoService);
} else {
OAuthRequest request = new OAuthRequest(Verb.GET, vimeoAPIURL);
request.addQuerystringParameter("method", "vimeo.oauth.checkAccessToken");
Response response = signAndSendToVimeo(request, "checkAccessToken", true);
if (response.isSuccessful()
&& (response.getCode() != 200 || response.getBody().contains("<err code=\"302\"")
|| response.getBody().contains("<err code=\"401\""))) {
vimeoToken = getNewToken(vimeoService);
}
}
return vimeoToken;
}
Here's getNewToken:
/**
* Gets authorization URL, pops up a dialog asking the user to authenticate with the url and the user
* returns the authorization code
*
* #param service
* #return
*/
private static Token getNewToken(OAuthService service) {
// Obtain the Authorization URL
Token requestToken = service.getRequestToken();
String authorizationUrl = service.getAuthorizationUrl(requestToken);
do {
String code = JOptionPane.showInputDialog("The token for the account (whatever)" + newline

+ "(click the 'x' or input the letter 'q' to cancel." + newline
+ "If you input an invalid code, I'll keep popping up).", authorizationUrl + "&permission=delete");
if (code == null) {
return null;
}
Verifier verifier = new Verifier(code);
// Trade the Request Token and Verfier for the Access Token
System.out.println("Trading the Request Token for an Access Token...");
try {
Token token = service.getAccessToken(requestToken, verifier);
System.out.println(token); //Use this output to copy the token into your code so you don't have to do this over and over.
return token;
} catch (OAuthException ex) {
int choice = JOptionPane.showConfirmDialog(null, "There was an OAuthException" + newline
+ ex + newline
+ "Would you like to try again?", "OAuthException", JOptionPane.YES_NO_OPTION);
if (choice == JOptionPane.NO_OPTION) {
break;
}
}
} while (true);
return null;
}
Here's signAndSend:
/**
* Signs the request and sends it. Returns the response.
*
* #param request
* #return response
*/
public static Response signAndSendToVimeo(OAuthRequest request, String description, boolean printBody) throws org.scribe.exceptions.OAuthException {
System.out.println(newline + newline
+ "Signing " + description + " request:"
+ ((printBody && !request.getBodyContents().isEmpty()) ? newline + "\tBody Contents:" + request.getBodyContents() : "")
+ ((!request.getHeaders().isEmpty()) ? newline + "\tHeaders: " + request.getHeaders() : ""));
service.signRequest(accessToken, request);
printRequest(request, description);
Response response = request.send();
printResponse(response, description, printBody);
return response;
}
I have written a REST web service with Jersey Server (that totally rocks !).
I am now developing the client part of it, with Jersey Client as well.
On the server side, I have chosen a DIGEST authentication, because I personally think that BASIC authentication is an heresy that should be marked as "DEPRECATED" in our heads.
Unfortunately, I do not see any support of the Digest authentication on the client side.
For BASIC authentication, one does something like :
client.addFilter(
new HTTPBasicAuthFilter(
user,
password));
But I see no "HTTPDigestAuthFilter" counterpart.
Am I missing something ?
Thanks for your help,
Raphael
I have just implemented it.
I have created a feature request in the Jersey issue tracker, and posted my implementation there, as attachment :
https://jersey.dev.java.net/issues/show_bug.cgi?id=542
It works fine for communicating with a DIGEST authentication of a Tomcat server.
I have not tested for other web servers yet.
Here I wrote some random uri. Please fill your desired URI
For sample testing you can take help of google services which are available in the internet for open.
