Multiple sockets override itself

My Code
I want to make a multiple connection to a telnet console. This project is for Teamspeak and Teamspeak just communicate with telnet. I´ve a object that create a telnet connection as socket with the net lib. If we have just one instance to connect all works fine and I get the serverlist over the telnet connection back. But if I´ve two instance he says invalid loginname or password. That login informations are correct and he also try just to connect to one server.
My Class:
/*

reader.on("line", function(line) {
var s = line.trim();
console.log(line);

How I open the class
if I call example one all works fine but example two has the descriped error.
Example 1:
test1 = new TeamspeakQueryClient({
"alias": "First-Coder Testinsance",
"ip": "first-coder.de",
"port": 10011,
"client": "serveradmin",
"password": "SECURE"
});
Example 2:
test1 = new TeamspeakQueryClient({
"alias": "First Insance",
"ip": "HIDDEN",
"port": HIDDEN,
"client": "serveradmin",
"password": "SECURE"
});
test2 = new TeamspeakQueryClient({
"alias": "Second Instance",
"ip": "HIDDEN",
"port": HIDDEN,
"client": "serveradmin",
"password": "SECURE"
});
Screenshots
Picture of the error in the console

According to your error, your second instance is not sending the correct login:
error id=520 msg=invalid\sloginname\sor\spassword
The additional errors displayed are due to your code not handling errors correctly.
For example:
socket.on("connect", function() {
...
if(err === null) {
if(err.id === 3329) {
If err === null, why would err have an element id?
Most likely this is code error, and you actually meant err !== null
$this.SendCommand("serverlist", null, function(err, response, rawResponse){
console.log(response);
if(response[0] === undefined) {
This error triggers because the (above) previous error was not caught.
At this point, the client is not logged in (authorized).
So when the serverlist command is sent, it riggers another error.
This additional error is also no handled, instead response is immediately used.

Nodejs + Q promise + method return based on url type

I am using node js for backend, also using q promise package.
Question : I am trying to get third party product details.
1. www.abcd.com 2. www.xyz.com - this method i handle in backend.
Possible url:
localhost:8080/search?type="abcd";
localhost:8080/search?type="xyz";
localhost:8080/search;
If the above URL type is abcd means need to search some different thridparty(www.abcd.com) http url;
If the above URL type is xyz means need to search some other different thridparty(www.xyz.com) http url
If the above URL didn't get type means need to search www.abcd.com if the result found means then return response, if result not found means need to call www.xyz.com url and then return response. (Note - here two third party api need to call)
Code:
router.get('/search', function(req, res, next) {
if (!( typeof req.query === 'undefined' || req.query === null || req.query == "")) {
var type = req.query;
}
var spec = {
resp : {}
};
Q(spec).then(function(spec) {
var deferred = Q.defer();
var optionsget = {
host : 'abcd.com',
method : 'GET'
};
var reqGet = https.request(optionsget, function(res) {
var getProductInfo = '';
res.on('data', function(d) {
getProductInfo += d;
});
res.on('end', function() {
if (( typeof message == 'undefined') && (!( typeof items === 'undefined' || items === null))) {
spec.resp.list = items;
deferred.resolve(spec);
} else {
spec.resp.message = message;
deferred.reject(spec);
}
});
});
reqGet.end();
reqGet.on('error', function(e) {
console.log(e);
deferred.reject(spec);
});
return deferred.promise;
}).then(function(spec) {
var deferred = Q.defer();
var optionsget = {
host : 'xyz.com',
method : 'GET'
};
var reqGet = https.request(optionsget, function(res) {
var getProductInfo = '';
res.on('data', function(d) {
getProductInfo += d;
});
res.on('end', function() {
if (( typeof message == 'undefined') && (!( typeof items === 'undefined' || items === null))) {
spec.resp.list = items;
deferred.resolve(spec);
} else {
spec.resp.message = message;
deferred.reject(spec);
}
});
});
reqGet.end();
reqGet.on('error', function(e) {
console.log(e);
deferred.reject(spec);
});
return deferred.promise;
}).then(function(spec) {
spec.resp.status = 'Success';
res.send(spec.resp);
}).fail(function(spec) {
spec.resp.status = 'Error';
res.send(spec.resp);
});
});
I this is chilly question. I understand need to check the type and implement. I thought we need to add some different function for both (abcd and xyz) then can call that method based on type.
Please suggest to good way.

Interaction in a Dynamic action between javascript and plsql tasks

I'm trying to execute several pl/sql blocks in a Dynamic Action, with feedback to the end user with a modal dialog reporting the current satus.
Something like:
Processing Step 1...
/*Run pl/sql code for step 1*/
Processing Step 2...
/*Run pl/sql code for Step 2*/
and so on...
Both, the pl/sql and javascript code, run as intended but when I combined them on a Dynamic Action in the sequence:
1 - Execute Javascript
2 - Execute PL/SQL block /* With wait for result option checked*/
3 - Execute Javascript
4 - Execute PL/SQL block
The status dialog is not been shown, however the pl/sql blocks are completed without problems.
I realize that this must be something related to javascript not been multithreaded, so I've moved the pl/sql block to application processes and run them as ajax calls like this:
function something(){
var get;
var result = 0;
updateStatus('Running Step1');
get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=P6_STEP_1',0);
result = get.get();
if(result > 0){
updateStatus('Running Step 2');
get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=P6_STEP_2',0);
result = get.get();
}
closeStatusDialog();
}
But still, as before, the processes run fine but the dialog doesn't appear. Finally I added a setTimeOut function to each call, like this:
function something(){
var get;
var result = 0;
updateStatus('Running Step1');
get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=P6_STEP_1',0);
result = setTimeOut(get.get(),500);
if(result > 0){
updateStatus('Running Step 2');
get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=P6_STEP_2',0);
result = setTimeOut(get.get(),500);
}
closeStatusDialog();
}
But still nothing. What can I do to get this running as needed?.
I've checked the browser console and no exeptions are been thrown, likewise with the pl/sql blocks.

I've solved it, although the solution doesn't rely on dynamic actions, just javascript and applicacion processes. I'm posting this for anyone with a similar problem.
The htmldb_Get Javascript object is an oracle-apex wrapper for the XMLHttpRequest AJAX object. Poorly documented though.
I've found a copy of the code (at the bottom) and it turns out it has another function called GetAsync that allows to pass a function as a parameter to asign it to the onreadystatechange attribute on the XMLHttpRequest object, which will be executed each time the attribute readyState of the underlying XMLHttpRequest changes.
The function passed as a parameter can't have parameters on its own definition.
So, instead of calling get() on the htmldb_Get object you need to call GetAsync(someFunction)
With this solution in my case:
function something(){
var get;
get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=P6_STEP_1',0);
get.GetAsync(someFunctionStep1);
}
function someFunctionStep1(){
if(p.readyState == 0){ /*p is the underlying XMLHttpRequest object*/
console.log("request not initialized");
updateStatus('Running Step 1');
} else if(p.readyState == 1){
console.log("server connection established");
} else if(p.readyState == 2){
console.log("request received");
} else if(p.readyState == 3){
console.log("processing request");
} else if(p.readyState == 4){
console.log("request finished and response is ready");
callStep2();
}
}
function callStep2(){
var get;
get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=P6_STEP_2',0);
get.GetAsync(someFunctionStep2);
}
function someFunctionStep2(){
if(p.readyState == 0){
console.log("request not initialized");
updateStatus('Running Step 2');
} else if(p.readyState == 1){
console.log("server connection established");
} else if(p.readyState == 2){
console.log("request received");
} else if(p.readyState == 3){
console.log("processing request");
} else if(p.readyState == 4){
console.log("request finished and response is ready");
closeDialog();
}
}
Here's the htmldb_get definition, at the end is the GetAsync function

return multiple ResultSet on IBM MobileFirst

I am facing problem when I try to invoke SQL resultSet for second time, and I get error Cannot read property "resultSet" from undefined. so I just wondering how to reuse resultSetor call multiple resultSet.
Main.js
function getAuthen(){
var username = $("#AuthUsername").val();
var password = $("#AuthPassword").val();
var invocationData = {
adapter: "ConnectDB",
procedure : 'getauthentication',
parameters : [username, password]
};
WL.Client.invokeProcedure(invocationData, {
onSuccess : getAuthenSuccess,
onFailure : getAuthenFailure
});
}
function getAuthenSuccess(result){
if(result.invocationResult.resultSet.length > 0)
{
$("#AuthDiv").hide();
$("#header_main").show();
$("#Menu").show()
$('#DisplayName').html(result.invocationResult.resultSet[0].NME);
$('#DisplaySurname').html(result.invocationResult.resultSet[0].SURNME);
} else {
getAuthenFailure();
}
}
function getAuthenFailure(result){
var alertTitle = "Fail to Login";
var alertText = "Please Enter Username and Password Correctly";
WL.SimpleDialog.show(alertTitle, alertText,[
{
text : 'OK',
handler : getLogout
}
]);
}
//***************************** END ************************\\
//*********** Get Problem On Going ************************//
function queryProblemOnGoing(){
var invocationDataP = {
adapter: "ConnectDB",
procedure : 'getproblemOngoing',
parameters : []
};
WL.Client.invokeProcedure(invocationDataP, {
onSuccess : getProblemOnGoingSuccess,
onFailure : getProblemOnGoingFailure
});
}
function getProblemOnGoingSuccess(result){
if(result.invocationResult.resultSet.length > 0)
{
window.alert("Success");
$("#Menu").show()
// displayQueryOnGoing(result.invocationResult.resultSet);
} else {
window.alert("Fail");
//getProblemOnGoingFailure();
}
}
function getProblemOnGoingFailure(result){
var alertTitle = "Fail to Retrive Data";
var alertText = "Please Contact Administrator";
WL.SimpleDialog.show(alertTitle, alertText,[
{
text : 'OK'
}
]);
}
function displayQueryOnGoing(result) {
for (var i =0; i < result.length; i++)
{
$('#problemOnGoingTable').append("<tr><td>" + result[i].CALLNO + "</td></tr>");
$('#problemOnGoingTable').append("<tr><td>" + result[i].CALLNOREF + "</td></tr>");
}
}
ConnectDB Adapter
var AuthenStatement = WL.Server.createSQLStatement("select NME, SURNME, CUS_ID from USERS where USERID = ? AND PASSWD = ?");
var problemOngoingStatement = WL.Server.createSQLStatement("select * from CALL”);
function getauthentication(userid, password) {
return WL.Server.invokeSQLStatement({
preparedStatement : AuthenStatement,
parameters : [userid, password]
});
}
function getproblemOngoing() {
return WL.Server.invokeSQLStatement({
preparedStatement : problemOngoingStatement,
parameters : []
});
}

I am not really sure how it is working the first time, or which part is working on the first time.
Anyway, I suspect that the problem is here:
for (var i =0; i < result.length; i++)
Perhaps you should change result.length to result.invocationResult.resultSet.length.

Why does my jQuery/YQL call not return anything?

I'm trying to access YQL with jQuery but am not getting a response:
http://jsfiddle.net/tastyapple/grMb3/
Anyone know why?
$(function(){
$.extend(
{
_prepareYQLQuery: function (query, params) {
$.each(
params, function (key) {
var name = "#{" + key + "}";
var value = $.trim(this);
if (!value.match(/^[0-9]+$/)) {
value = '"' + value + '"';
}
query = query.replace(name, value);
}
);
return query;
},
yql: function (query) {
var $self = this;
var successCallback = null;
var errorCallback = null;
if (typeof arguments[1] == 'object') {
query = $self._prepareYQLQuery(query, arguments[1]);
successCallback = arguments[2];
errorCallback = arguments[3];
} else if (typeof arguments[1] == 'function') {
successCallback = arguments[1];
errorCallback = arguments[2];
}
var doAsynchronously = successCallback != null;
var yqlJson = {
url: "http://query.yahooapis.com/v1/public/yql",
dataType: "jsonp",
success: successCallback,
async: doAsynchronously,
data: {
q: query,
format: "json",
env: 'store://datatables.org/alltableswithkeys',
callback: "?"
}
}
if (errorCallback) {
yqlJson.error = errorCallback;
}
$.ajax(yqlJson);
return $self.toReturn;
}
}
);
$.yql(
"SELECT * FROM github.repo WHERE id='#{username}' AND repo='#{repository}'",
{
username: "jquery",
repository: "jquery"
},
function (data) {
if (data.results.repository["open-issues"].content > 0) {
alert("Hey dude, you should check out your new issues!");
}
}
);
});

You need to leave off the quotes (since they're added already as part of the parameterization process), this:
"SELECT * FROM github.repo WHERE id='#{username}' AND repo='#{repository}'"
...which results in:
SELECT * FROM github.repo WHERE id='"jquery"' AND repo='"jquery"'
should just be:
"SELECT * FROM github.repo WHERE id=#{username} AND repo=#{repository}"
....which results in:
SELECT * FROM github.repo WHERE id="jquery" AND repo="jquery"
Once you correct this, the format coming back is:
{"query":{"count":"1","created":"2010-12-25T21:49:01Z","lang":"en-US","results":{"repository":{"url":"https://github.com/jquery/jquery","has-downloads":{"type":"boolean","content":"false"},"organization":"jquery","homepage":"http://jquery.com/","pushed-at":{"type":"datetime","content":"2010-12-25T09:56:56-08:00"},"created-at":{"type":"datetime","content":"2009-04-03T08:20:14-07:00"},"has-wiki":{"type":"boolean","content":"false"},"fork":{"type":"boolean","content":"false"},"forks":{"type":"integer","content":"496"},"private":{"type":"boolean","content":"false"},"open-issues":{"type":"integer","content":"35"},"name":"jquery","description":"jQuery JavaScript Library","watchers":{"type":"integer","content":"5387"},"owner":"jquery","has-issues":{"type":"boolean","content":"false"}}}}}
So you need a .query in there, like this:
if (data.query.results.repository["open-issues"].content > 0) {
You can test it out here.
