I am developing a webapplication which is a cab booking system.
The working is when the customer books a cab the request information will sit into the database. The admin will view it in the web-application and book cab for the customer.
What I want to do is the admin must get a notification that will show the total number of requests received for every 1 min.
How can I do this? What is that I need to use for doing this?
I'm using servlets,jsp and mysql.
Any help would be much appreciated!Thanks!
You need to maintain the time-stamp feature in database side,based on time-stamp we will get the latest requests comming from customer.and also you need to use the ajax calling.

I'm making a web app project using Laravel and React. The data is displaying normally, but each time it is updated the page need to be refreshed manually in order to show the new information's in the database.
How can I display for example the last users registered in real time? Without refreshing the page?
I'm currently using MySQL.
You need to use websockets to listen for a notification and trigger an ajax request to get the data from the server and update the front end
A few different options

I've searched and I can only find tutorials to pull info from a server to update the latest info of my PWA app using JSON. But I can't find any way and any example to fetch data back to a server to mantain for instance a Database updated and display that to all users which may use that PWA.
For example, I have a PWA that let me login (client-server communication), then it displays a list of contacts that were stored in a Database. I can delete, modify or add new users to this list from my PWA app, and after doing that, they'll update on my server Database, so if my friend Paul, wants to check the updated list from his account, he'll see the new changes.
How Can I do that? Which language would I have to use, php and Javascript (Ajax)? Which is the most fluid and optimized way to do it according to a Progressive Web App.
I guess you are trying to store user changes back to the server(webservice and then to the data base).
You have to make an AJAX call to your web service and pass the required data needed to store in DB.
Here is an example.

Depending on the framework you are using, you might have more options to call a web service. Like here is an example for Angular -> https://www.w3schools.com/angular/angular_http.asp
Today I have been given a new task and dont know how to go about it. I have two websites written in Spring MVC that does registration and payment processing.
On beginning the registration process on the first portal, when it comes to payment the user is thereby directed to the second portal to complete the payment and thereby returns the person back to the first website.
The registration details entered by the user is required to be transferred from the first portal to the second portal in other to generate the required payment processing.
My question is, please what are the steps to channel my efforts towards using JSON to transfer data from one portal to another considering data security using Spring MVC. Please I need your ideas.
I have a web app with a MySQL database we maintain in the cloud that we are trying to integrate with our QuickBooks Online account. We want to sync data between or web app's database and QuickBooks online, such as customer names and addresses. If they update their address in or web app, it's easy to then update it in QuickBooks online using the QuickBooks Online API. However, if they tell us their new address over the phone and we change it directly in QuickBooks online, we have no idea how to have that trigger something so that it automatically updates our MySQL web app. How do we go about doing this or learning about this process?
Intuit/QuickBooks has an API that's specifically geared towards this use-case. From the docs:
The change data capture (CDC) operation returns a list of entities that have changed since a specified time. This operation is for an app that periodically polls Data Services and then refreshes its local copy of entity data.
Docs are here:
https://developer.intuit.com/docs/0100_accounting/0300_developer_guides/change_data_capture
Basically you make an OAuth signed HTTP GET request like this:
https://quickbooks.api.intuit.com/v3/company/1234/cdc?entities=Class,Item,Invoice&changedSince=2012-07-20T22:25:51-07:00
And you get back a list of objects that have changed since the given date/time.
Your application can remember the last time you called this, and periodically call this API to get things that have changed since the last time you called it.
You get back something like this:
<IntuitResponse xmlns="http://schema.intuit.com/finance/v3" time="2013-04-03T10:36:19.393Z">
<CDCResponse>
<QueryResponse>
<Customer>...
</Customer>
<Customer>...
</Customer>
</QueryResponse>
<QueryResponse>
<Invoice>...
</Invoice>
<Invoice>...
</Invoice>
</QueryResponse>
</CDCResponse>
</IntuitResponse>
I was wondering if it is possible to have multiple custom push notifications setup in a single AIR App.
What I am trying to do is allow users to setup custom alerts based on information they would like to receive for example say user 1 would like to know when new actions or drama movies are released on DVD, user 2 would like to know when new comedies are released, user 3 would like to know when any new movie is released.
This is a simple example and there are possibly 1000's of options (postcode/zip information).
Thanks
Technically, there's nothing that wouldn't allow you to do this.
The implementation is mostly backend related though, let me just quickly draft a design for that here;
The user's device registers for push notifications at your backend service.
Your service takes the user's id stores in a DB and passes the device token to the corresponding push notification server.
Once the registration is completed, the user selects what items he'd like to get notified of (naturally your backend service has to know this information as well to store it in the DB).
As soon as a new action movie (or whatever kind of information the user registered for) is available, your service looks in the DB what users registered for that kind of movies and sends a message via push.
So a simple database and some server side scripting will get you going.
