Next simple Java program using Event Socket interface to control FreeSWITCH. First you should read: Mod event socket on wiki freeswitch Java ESL Client on wiki freeswitch Next you should not forget to change event_socket.conf.xml (to allow connections from any host on the network): Now we can write simple java ESL program for connecting to the FreeSWITCH. MyEslEventListener.java package myeslevent; import java.util.Map; import java.util.Set; import org.freeswitch.esl.client.IEslEventListener; import org.freeswitch.esl.client.transport.event.EslEvent; import org.slf4j.Logger; import org.slf4j.LoggerFactory; public class MyEslEventListener implements IEslEventListener { private final Logger log = LoggerFactory.getLogger(this.getClass()); @Override public void eventReceived(EslEvent event) { log.info("eventReceived [{}]\n[{}]\n", event, getEventToLog(event)); } @Override public void backgroundJobResultReceived(EslEve...

I would like to show simple Java program which use XML-RPC interface to do some freeswitch commands. We should on freeswitch console load mod_xml_rpc: Worth checking out if it works, in web browser type: http://fshost8080/webapi/help If you see "FreeSWITCH help" it works. Next we download Apache XML-RPC library. Now we create Java program (using Apache XML-RPC): package fstest1; import java.net.URL; import java.util.Scanner; import org.apache.xmlrpc.client.XmlRpcClient; import org.apache.xmlrpc.client.XmlRpcClientConfigImpl; public class FsTest1 { public static void main(String[] args) { System.out.println("------ hello freeswitch -------\n"); XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl(); XmlRpcClient client = new XmlRpcClient(); try { config.setServerURL(new URL("http://fshost:8080/RPC2")); config.setBasicUserName("freeswitch"); config.setBasicPassword("works"); ...

I built MotoAds demo application in AngularJS but it did not have any server layer. Data was read directly from the json files. So I was decided to build the server side services. I know pretty well JEE and relational database, so I could use it. But I want to know something new so I chose NodeJS nad MongoDB. Thanks to this decision I got a full stack JavaScript application. It's incredible to use JavaScript to build the complete application. Now MotoAds demo application consists of: User interface in AngularJS and Bootstrap with full CRUD operations: add, read, edit and remove adverts. Server service layer was built in NodeJS with RESTful serrvices. To simplify the use of a NodeJS I used ExpressJS. Database: all data except the pictures are stored in MongoDB. So let's see how to add the CRUD operations in AngularJS with services in NodeJS with MongoDB. Step 1 We write in services.js access to our RESTful services: 'use strict'; var motoAdsServ...

Lately I struggled to get access to facebook by JSONP. I try to do it in AngularJS with factory and resource. I want to share with people my solution. Let's try to connect to the Facebook Graph. Firstly, we create index.html file with input graph.username , after type a value there is called getGraph() . The result of the calling this function is saved in $scope.result so we can display it. AngularJS resource with JSONP

E2E (end-to-end) tests result: Application folders tree: In previous post I showed how to write and run unit tests. Now, I will present how to test DOM manipulation or the wiring of our application. Angular Scenario Runner which simulates user interactions that will help us to do that. Recall adverts.html code which we should know to simulate user interaction: Adverts {{model.name}} Adverts search Country Region Year of production Filters: {{filter.brandName}} {{filter.modelName}} {{filter.country.name}} ...

Unit tests result: Application folders tree: In Angular the controller is separated from the view so it is easy to add the unit tests to MotoAds application. Recall the controller code which will be tested ( controllers.js ): motoAdsApp.controller('AdvertsController', ['$scope', 'Brand', 'Country', 'Advert', function($scope, Brand, Country, Advert) { $scope.oneAtATime = true; $scope.brands = Brand.query(); $scope.countries = Country.query(); $scope.sortByCols = [{ "key": "year", "name": "Year" }, { "key": "price", "name": "Price" }]; $scope.adverts = []; var allAdverts = Advert.query(filterAdverts); $scope.filter = { brandName: null, modelName: null, country: null, region: null, yearFrom: null, yearTo: null }; $scope.isAnyFilter...

I have just been learning AngularJS and decided to build demo application that cover more techniques than the tutorial on angularjs.org . This application is only demo so it do not have complete server side, some features have the todos and there is not any test. This demo application is some kind of automotive adverts portal, so I called it MotoAds. It has two main features: List of adverts – includes an advanced filtering and sorting. Add advert – a form with some client side field validations. MotoAds application looks like this: Application folders tree: Root file index.html included external resource: bootstrap.css (2.3.2) angular.js, angular-resource.js (1.0.8) ui-bootstrap-tpls-0.6.0.js (0.6.0) and internal resource: app.css app.js services.js controllers.js Bootstrap angular application, add navigation and route templates In index.html we auto-bootstrap the angular application by defining directive ng-app : In app.js we define new...
