I want to get followers Id's for a particular userId using java program. where I want to implement the cursor concept with rate limit set ... Can any one post me the code.
Use the following code snippet to get follower id. After getting the ids you use show user to get other details. Remember to use this code in background thread like in asynctask.
long[] tempids = null;
ConfigurationBuilder config =
new ConfigurationBuilder()
.setOAuthConsumerKey(custkey)
.setOAuthConsumerSecret(custsecret)
.setOAuthAccessToken(accesstoken)
.setOAuthAccessTokenSecret(accesssecret);
twitter1 = new TwitterFactory(config.build()).getInstance();
while(cursor != 0) {
try {
IDs temp = twitter1.friendsFollowers().getFollowersIDs("username", cursor);
cursor = temp.getNextCursor();
tempids = temp.getIDs();
} catch (twitter4j.TwitterException e) {
System.out.println("twitter: failed");
e.printStackTrace();
return null;
}
if(tempids != null) {
for (long id : tempids) {
ids.add(id);
System.out.println("followerID: " + id);
}
}
}

I want to use blocking handler, but still get an error:
java.lang.IllegalStateException: Response has already been written
Here is my code:
Server.java
r.route("/api/details/send/").handler(BodyHandler.create());
r.route("/api/details/send/").handler(ctx-> {
JsonArray ja = ctx.getBodyAsJsonArray();
JsonArray params = new JsonArray();
vertx.executeBlocking(futur -> {
for(int i =0; i<ja.size();i++) {
JsonObject req = new JsonObject();
req.put("QUERY", "INSERT INTO detailsfacture VALUES ('',?,?,?,?,?,?,?)");
req.put("DB", "MYSQL_");
params.add(ja.getJsonObject(i).getValue("typefacture"))

con.updateWithParams(sql,reqParams.getJsonArray("PARAMS"), query -> {
if(query.succeeded()){
UpdateResult urs = query.result();
req.reply(urs.toJson());
//req.reply(query.result());
}else{

}
});
}catch(Exception e){

}
} else {

}
});
}catch(Exception e){

P.S. : When I remove executeBlocking only the first records is registred in my database.
Regards.
You insert entities into detailsfacture in a loop. For each insert you call following:
ctx.response().putHeader("content-type", "application/json").end(res.result().body().toString());
As you can see you call the end(...) method of the response object. Thats where the IllegalStateException comes from. As the documentation states:
Once the response has ended, it cannot be used any more.
So you problem has nothing to do with the executeBlocking.
You should take a look at the write(...) method of HttpServerResponse. For each insert you should call write(...) instead of end(...). But this will only work if you know the complete length of the whole response because you need to set the header Content-length. If you are finished with all inserts you need to call end() to complete the response. Also you should only set the header once and not for each insert.
Now some additional comments. I don't see the need for executeBlocking in your case. Because of the problem with Content-length I recommend to wrap each insert with a Future and compose all of them with CompositeFuture. The Future futur is used the wrong way. The send(...) method of Event bus is not blocking and asynchronous. So the futur.complete(result) is called right after you send all your inserts. Also it's strange that the consumer consumes MYSQL_EXECUTE_WITH_PARAMS and the send sends to EXECUTE.
I tried another solution to get my query like that (?,?,...,?),(?,?,...,?),..,(?,?,...,?).
Here is my code :
public static String getMultipleInsertReq(String table, JsonArray columns,JsonArray data){
JsonObject tab= Tables.Tables_list.getJsonObject(table); // name of table
String sql = "";
if(tab != null){
sql = "INSERT INTO "+table + "( ";
if(columns == null){
columns = tab.getJsonArray("COLS"); //columns from ur database
}
if(columns!=null){
for(int i=0;i<columns.size();i++){
if(i==columns.size()-1){
sql+=columns.getString(i)+") VALUES";
}
else{
sql+=columns.getString(i)+",";
}
}
for(int i =0; i<data.size();i++){
for(int j=0; j<columns.size();j++){
if(j==columns.size()-1 && i!=data.size()-1){
sql+="?),";
}
else if (i==data.size()-1 && j==columns.size()-1){
sql+="?)";
}
else if (j==0){
sql+="(?,";
}
else{
sql+="?,";
}
}
}
return sql;
}
}
return null;
}
Hope it helps.
P.S.: it's only a query builder so you can adapt it depending on your needs.

i'm new to android and java.
i made a cardview and populated it with a simple loop like so:
private ArrayList<DataObject> getTheData(){
ArrayList res = new ArrayList<DataObject>();
for (int index = 0; index < 5; index++){
DataObject obj = new DataObject("shit","happen");
res.add(index,obj);
}
return res;
}
it worked. now i created a database and want to populate it with this data. so i have this:
public ArrayList<DataObject> getData() {
SQLiteDatabase db = this.getReadableDatabase();
ArrayList res = null;
try {
res = new ArrayList<DataObject>();
String selectQuery = "SELECT * FROM quotes a LEFT JOIN authors b ON b.author_id=a.quote_author";
Cursor cursor = db.rawQuery(selectQuery, null);
if (cursor != null) {
if (cursor.moveToFirst()) {
do {
Log.d("CHECKDB",cursor.getString(cursor.getColumnIndex("first_name")) + " " + cursor.getString(cursor.getColumnIndex("last_name")));
Log.d("CHECKDB2",cursor.getString(cursor.getColumnIndex("quote_text")));
DataObject obj = new DataObject(
cursor.getString(cursor.getColumnIndex("first_name")) + " " + cursor.getString(cursor.getColumnIndex("last_name")),
cursor.getString(cursor.getColumnIndex("quote_text"))
);
res.add(obj);
} while (cursor.moveToNext());
}
}
} catch (SQLiteException se) {
Log.e(getClass().getSimpleName(), "Could not create or Open the database");
} finally {
if (db != null)
db.close();
}
return res;
}
the log show all the results, but when i run the app i get the last result the right amount of times. in this case 4 quotes in my database, so i see 4 but the last one 4 times.
please , since i'm new to it, good explanations will be appreciated.
the issue was that my dataobject attributes were set to static

Could this be lazy fetching on the server side by hbase. This means if you return the list hbase won't get a trigger to actually read the list and you will simple get an empty list. I don't know a correct solution, in the past I've seen a similar problem on GAE. This could by solved by simply asking the size of the list just before returning it to the client.
I don't have the exact answer, but I have an advise. In similar situation I put my own trace to check every step in my program.
On the server side before return put : System.out.println("size of table="+deviceidList.size());
You can put this trace in the loop for deviceidList;
How can I get the tweets when I have the tweet ID and the user ID ? I have a file containing lines like :
userID tweetID
I guess I should go by :
Query query = new Query("huh ?");
QueryResult result = twitter.search(query);
List<Status> tweets = result.getTweets();
but I have no clue how to spell the query
Thanks
Well it was no search call. The tweet apparently is called Status and the code to retrieve one by ID is :
final Twitter twitter = new TwitterFactory().getInstance();
twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_KEY_SECRET);
AccessToken accessToken = new AccessToken(TWITTER_TOKEN,
TWITTER_TOKEN_SECRET);
twitter.setOAuthAccessToken(accessToken);
try {
Status status = twitter.showStatus(Long.parseLong(tweetID));
if (status == null) { //
// don't know if needed - T4J docs are very bad
} else {
System.out.println("#" + status.getUser().getScreenName()
+ " - " + status.getText());
}
} catch (TwitterException e) {
System.err.print("Failed to search tweets: " + e.getMessage());
// e.printStackTrace();
// DON'T KNOW IF THIS IS THROWN WHEN ID IS INVALID
}
The accepted answer is no longer valid. Based on the answer in this page, the code should be changed to the following:
String consumerKey = xxxxxxx,
consumerSecret = xxxxxxx,
twitterAccessToken = xxxxxxx,
twitterAccessTokenSecret = xxxxxxx,
Tweet_ID = xxxxxxx;
ConfigurationBuilder builder = new ConfigurationBuilder();
builder.setOAuthConsumerKey(consumerKey);
builder.setOAuthConsumerSecret(consumerSecret);
Configuration configuration = builder.build();
TwitterFactory factory = new TwitterFactory(configuration);
final Twitter twitter = factory.getInstance();
//twitter.setOAuthConsumer(consumerKey, consumerSecret);
AccessToken accessToken = new AccessToken(twitterAccessToken, twitterAccessTokenSecret);
twitter.setOAuthAccessToken(accessToken);
try {
Status status = twitter.showStatus(Long.parseLong(Tweet_ID));
if (status == null) { //
// don't know if needed - T4J docs are very bad
} else {
System.out.println("#" + status.getUser().getScreenName()
+ " - " + status.getText());
}
} catch (
TwitterException e) {
System.err.print("Failed to search tweets: " + e.getMessage());
// e.printStackTrace();
// DON'T KNOW IF THIS IS THROWN WHEN ID IS INVALID
}
A very easy way to get a list of tweets by their ID is to use the lookup function like this:
public static void main(String[] args) throws TwitterException {
ConfigurationBuilder cfg = new ConfigurationBuilder();
cfg.setOAuthAccessToken("key");
cfg.setOAuthAccessTokenSecret("key");
cfg.setOAuthConsumerKey("key");
cfg.setOAuthConsumerSecret("key");
Twitter twitter = new TwitterFactory(cfg.build()).getInstance();
long[] ids = new long [3];
ids[0] = 568363361278296064L;
ids[1] = 568378166512726017L;
ids[2] = 570544187394772992L;
ResponseList<Status> statuses = twitter.lookup(ids);
for (Status status : statuses) {
System.out.println(status.getText());
}
}
The advantage of using lookup is that you can get with a sigle call up to 100 tweets, this means that if you have to download a big number of tweets you will need to do a lot less calls to the twitter API and speed up the process (this is because twitter limits the number of calls you can do).
You can even check the number of calls that you can do before twitter puts you in timeout like this:
RateLimitStatus searchLimits = twitter.getRateLimitStatus("statuses").get("/statuses/lookup");
int remain = searchLimits.getRemaining();
int limit = searchLimits.getLimit();
int secToReset = searchLimits.getSecondsUntilReset();
System.out.println(remain); // this returns the number of calls you have left
System.out.println(limit); // this returns how many calls you have max(this is a fixed number)
System.out.println(secToReset); // this returns the number of second before the reset
// after the reset you return to have the number of calls specified by "limit"
I have a plugin registered for when an account is created or updated, this is registered for the post stage.
The plugin works fine when a user creates or updates an account through the CRM interface, however when an account is created uging the API the plugin fails with the ever helpful 'server was unable to process the request' message. if an account is updated through the api the plugin also works correctly.
anyone have any ideas why?
UPDATE:
here is the create code
account = new CrmService.account();

Sometimes it can be difficult to see the actual source of an error in plugins. In moments like this tracing is your friend. You can use this tool to enable tracing. When you have the trace files, try to search them for the error you got in your exception. This should tell you more details about what is failing.
Turns out this was due to me expecting data that was not there due to some weird behaviour in CRM.
I was taking the dynamicEntity passed to the plugin like so
entity = (DynamicEntity)context.InputParameters.Properties[ParameterName.Target];
But this was missing critical things like accountid. fixed it by using the PostEntityImage entity instead, which had all of the expected data like so
entity = (DynamicEntity)context.PostEntityImages[ParameterName.Target];
