Hello i working on project and i dont now how to start, I will be have a frontend server(spring boot) and mongoDb for database and frontend apps reactjs for web and android app for mobile. i would like to have server like "firebase realtime sync data for client", what in wont when someone send post pust request from mobile to my server i would like to show this post data on react app, or when someone change data on react app this data will be changed on other deskop (somethink like notes List). is there a way how i cant start how to create firebase logic ... i just cant use firebase for the some reason.
To implement a "realtime database" like Firebase you will need to use the "websocket" technical. your reacjs client will open the websocket and the server will push any db update to the listening websockets.
from client side you will have to implement your own cache (because firebase client sdk use cache) and implement the REST request.
From server side you will have to develop the rest api. The db Collections structure may be different from firebase, and the way you query them with springboot also.
The secuity data access will have to be redesigned as well.
the a lot of work, but interresting.
I am looking at developing a web api for my business rules/database access.
I can use Postman to test the api locally but I also need to develop the client web site.
Is it just a case of running the web api locally and then developing the client site to use the local web api urls?
e.g. http://localhost/api/getcustomer/1
Also when it eventually goes live what do I need to look into in order to secure it all?

We currently have an installation of IBM content navigator that we built a feature inside, this feature shows another web application installed on the same server inside an iFrame, this application connects to CPE using Java WS APIs to do some operations using the ICN logged in user credentials.
The main problem we are facing is that in our current solution the user logs in twice, once to log in to the ICN, and another to log in to the web application, which is undesirable and we need to eliminate this second login and implement some sort of SSO.
One option available is using Kerberos, however as it currently stands the FileNet Java api does not support Kerberos at the moment (only .Net).
Any ideas are much appreciated

If your web application is deployed on the same WebSphere Cell, you don't need to use Kerberos. Kerberos need to support SSO between WAS and client only, not between application and client.
You don't need to use createSubject(), just get it from security context and provide it to CPE.
We have this architecture:
Web Server: Web Application is deployed (html, javascript, css)
Application Server: WebApi is deployed
Problem is , I cannot make ajax request to reach Application Server because its behind firewall.
The Web Application is supposed to be used publicly to the internet users.
What changes should we do to make it work?
Should we move our Web Application to Application Server? But how would this be accessible on internet.
Thanks in advance for suggestions/advice.
You're going to have to put an exception in the firewall for the address of your web server... that way your web server can access the API but nothing else can (well, not quite nothing else - other stuff on that web server can but that can easily be solved by having your web app hosted on it's own/dedicated web server).
If your Web Application makes direct calls to the Web API endpoint (e.g. is a single page application that use a client-side javascript framework like AngularJS and/or it uses AJAX calls to your application server address), there is no way for your clients to access your API if you do not allow public access to your application server.
That's because your client resides inside your users web browsers.
You have to allow incoming connections to your Application Server through internet in your firewall.
Well, it all depends on how you look at things and how distributed your application should be (criteria like load, security).
In general, Web API might be just one more client (from your applications server perspective).
On the other hand, in robust/distributed system, you would have Web API only as an endpoint (controllers, mappers and things like that) that your mobile/ajax clients send requests to and then Web API communicates to Application server (where your business logic is).
Having Web API communicate to DB directly is not a good idea because as you add clients to application server (mvc, web api, services, etc...) then you have as many db access points as you have clients. So, its a code maintenance problem plus a problem of your view tier being aware of DB.
Ideally, you need Application server as a tier where all your business logic is and its the one that all your clients target (mvc web app, web api, desktop, services, etc...) and that is the one that should communicate to your DAL. Also, then you can set firewall rules on your application server to allow incoming traffic from trusted sources (your other servers) instead from the whole internet (ajax).
I am trying to make 2 applications which uses Google Cloud Messaging.
My goal is to make a one application Android IBM Worklight which can receive Push notifications (CLIENT-SIDE) and another application a Tomcat Server Java Servlet (SERVER-SIDE).
However, I have absolutely no experience in using Google Cloud Messaging and it is my first time using Android IBM Worklight as client-side.
So I was hoping someone could point me in the right direction that I so could have 1st application using tomcat server sending the Push notifications (SERVER-SIDE) and another application using IBM Worklight as (CLIENT-SIDE) to receive the push notification.
I have been finding tutorials regarding this but I am stuck at implementation.
This tutorial link gave me an idea on how to do server side since i am using tomcat server. However the client-side is code is not what I am looking for since I am using IBM Worklight inside.
Another tutorial link show me how the push notification works at IBM Worklight for both client and server side. However, as mention earlier my server side is Tomcat server at Eclipse thus I think that I can't using this tutorial for server side.
As for client side, I think can use this tutorial since it is IBM Worklight however it is not using Google Cloud Messaging.
I would appreciate someone help me..Thanks :)
The second tutorial has the information you need. If you have your Worklight server set up on Tomcat, just follow the tutorial and deploy the push adapter to that server.
