Situation:
backend windows application <--> ejabberd server <--> android chat client side
Client side sends a custom iq query in JSON format via ejabberd server to backend windows app and it parses it correctly. When the backend windows app sends back a response to the client the single quotes in the JSON response are converted to ".
Configuration:
backend app - windows app (.net based application)
backend - Azure SQL
xmpp server - ejabberd 15.07
ejabberd server OS - Ubuntu Trusty
client side - android app using "asmack"
I am not sure what can be causing the error. Any help is appreciated.
Thanks.
This is standard XML escape sequence, you pretty much expect to have any of this characters &<>" to be replaced by one of special entities. Your xml parsing library should replace those automatically, maybe you are not using correct method to not get raw values? It may also be problem on producing end, where it escapes values twice (' -> " -> ") which after unescaping will give you " string, you would need to check what is actually send in network packet to be able to determine this.

I have my application in Delphi with MySQL as a database. This is a Desktop application with local Database connected using ADO components.
I have another web application done in PHP and MYSQL.
I want to merge both databases and connect the Delphi application to the cloud MySQL database.
Do I need to put all my logic in PHP scripts and access them from Delphi?
How Delphi to cloud connection can be established?
You can use FireDAC to connect to a database located in the cloud, as soon as your provider allows that connectivity.
But exposing you database to the internet is not the best secure architecture. As you suggest yourself with naming it, a much better architecture is REST. The idea is to write server side software - could be PHP - to accept REST requests from a client, execute it (access the database) and send a reply to the client.
Today's, the REST requests are frequently using JSON to pass requests and receive replies. JSON is supported by Delphi. In short, this is an ASCII representation for object properties.
If accessing the database directly is what you really want, look at this video by Stephen Ball showing how to access an MS-SQL database on Azure cloud. This would be pretty well the same with mySQL.
I am trying to select a app server platform to service JOSN & Soap POST requests from client app on Desktops. The app server runs on linux and use PHP code.
I searched and found PHP framework but that doesn't give you easy to use auth user/password, so you have to do the auth in app code. What is to use for simple request/response app server with secure auth like user/password on first request and then token like normal web servers.
Currently using Drupal 7 REST services module to handle request auth, but SOAP has security issues. Looking for better and light weight framework.
For your API : https://www.drupal.org/project/jsonapi (it's gonna be implemented in 8.7 anymay)
If you have an external authentication provider (like keycloak, azureAD…) : https://www.drupal.org/project/oauth2_jwt_sso
If you don't : https://www.drupal.org/project/simple_oauth
I'm having problem trying to access the MySQL server (I'd like to replace a table with another) provided as part of the Windows Azure service. I have downloaded the publishsettings XML file, and the closest thing that I can find is 'Data Source=us-cdbr-azure-east-a.cloudapp.net;'. However, it's not accessible from the web browser, so I'm not sure what to do next.
You can get the full connection string from the dashboard of your Azure Web Site
Then you can use those credentials in a MySQL administration program, such as MySQL Workbench.
I'm attempting to write a Windows Phone 7 application which needs to connect to a remote data source, in this case it's a MySQL database on a Linux server. I'm not able to move this over to MSSQL, nor to build any kind of windows-based solution (like a WCF web service on the server).
Is there a way for me to use my MySQL database from my Windows Phone 7 application? The MySQL assemblies don't seem to work on the phone. If not, what would the best solution for me to use this database from the phone?
You could build your self a service which would send you json or xml. this can easily be built using mono, python, Ruby, php or any technology that you are comfortable with.
You can build it in a restful manner where all you have to do is call urls in a HTTP GET to retreive data which you handle with the services.
and use the HTTP POST to submit changes to your service.
you can then from WP7 make calls to this service and consume the data.
WP7 does not support sockets at the moment. So your best bet is transfering your payloads over HTTP.
As I mentioned before, if you have access to the machines configuration. You could run Mono which isn't too far off of .Net in terms of language and functionality.
further more, from the phone you can use the Rx library to make these calls Async and keep your application responsive.
I have a hosting account at godaddy ruinning Linux. Is has MySQL. I am creating a J2ME application that runs on android and I was wondering if there is any simpler way to connect from j2me application to my MySQL server?
Is it required to install anything at my server? which I cannot do because of the shared account. Any way to just open the connection, update some data in the MySQL from j2me application?
It is quite simple. You just need to do HTTP application/x-url-form-encoded request on the midlet and set request property to HTTP.POST. Then stream form data as bytes. Receive those post variable using a server side language (i used PHP) like $_POST['var'] and in that server script write MySQL query like insert into .. VALUES.. etc.
I don't know if any DB drivers exist for J2ME. If you can't find them just make layer on the server and implement your own protocol for retrieving data via http or sockets
