I am using eclipse to develop an oracle MAF application. I set up the environment but i need now to connect my app to the oracle database on the server and i don't know how to start. Do i have to use the local sqlite database then sync with the server or connect directly to the server and how to do it?
thank you!
It's not possible to make a direct database connection MAF. You will have to expose your data in a web service and consume it in your mobile app.
One option you can consider is to expose the data in the database as a REST Service which you can invoke from a MAF application.
See this presentation on how to use OEPE to build a MAF application that invokes REST services: https://www.youtube.com/watch?v=pRdLSOVslQg
Hope this helps. Thanks for your interest in OEPE.

Here is the simple tutorial which describes that how can you make a REST web service in Oracle MAF, deploy it to web logic server using Jdeveloper and access it from your browser. I hope it'll help you:

Pervasync just released a new version (6.0.2) of its sync framework that supports synchronization of Oracle MAF SQLite databases with central Oracle, MySQL, SQL Server and PostgreSQL databases.
You can try this sample tutorial which having the step by step explanation.
To make it work, you need to use JDeveloper 12c (download it from here). It will contain WebLogic server as well.
In additional you need to have Android SDK for emulator (or) you can make use of Android device to deploy and run the application.
For Android Device:
You can deploy the application into machine and configure the mobile client app using virtual IP of that machine. So that it can be accessed from outside of the network.
For Emulator:
you can run the webservice and client in same machine by configuring the webservice IP as 127.0.0.1 this will route your client app into local machine (P.S: localhost does't works here)

I have created a project with MERN stack and want to host it. But as i came to know that netlify.app hosting site doesnt support hosting for database related projects as my project includes mongodb as a backend.
It will be a great help if anyone can suggest where should i host my project which can support mongodb as a backend also. And also any methods to do it that will be great help.
You can use AWS EC2 Linux instance, where you can keep your project and at the same time you can store your data. For the initial phase of your project, you can install MongoDB on the same machine.
I have created windows server VM and installed ofbiz framework with Demo data. The framework is working fine when accessed through VM itself, but I need a way to access it outside (through local browsers).
You need to open ports (8080 and 8443) to access it from outside the azure VM. Here you go on how to do that- https://learn.microsoft.com/en-us/azure/virtual-machines/windows/classic/setup-endpoints?toc=%2Fazure%2Fvirtual-machines%2Fwindows%2Fclassic%2Ftoc.json
You can also use the Apache OFBiz Mailing list for such queries - https://ofbiz.apache.org/mailing-lists.html
HTH!
I have bought a VDS (Virtual Dedicated Server) that Windows Server 2008 is installed on it. I needed to use server because I have developed a C# console application that can read data by TCP socket and write them in the MySQL database.
Now I need to start a website on this server. I think WAMP server is so easy for me.
Maybe in future a lot of people visit my website.
Is it a good idea to use WAMP server as a web server?
In principal there is nothing wrong with using WAMPServer as a LIVE webserver.
However, not the out of the box version.
Out of the box WAMPServer and XAMPP for that matter expect to be used as a single seat developer tool and while that is great for a click and go solution to get a developer up and running on Apache/MySQL and PHP in a few minutes it is not secure enough to be considered as a LIVE web facing webserver.
Now if you have the knowledge and experience to create an user account on Windows Server that has access to only what Apache needs to do its work, and can get Apache to run in that account instead of its default account (which has way to many privilages for a live server) and are prepared to explore all the Apache security features/modules that would be required for a web facing server then it is possible. However this is not a trivial task, and any mistakes or ommissions will leave your server open to the simplest of hacks.
In short, unless you really know what you are doing with Windows Server and Apache, you would be far better to pay for a professionally configured and managed web server environment.
I wish to deploy a lightswitch application for a small company. I want a central server hosting the database and then the silverlight client to run inside the network connecting to the server and updating the database with clients, etc.
I have made a working system using the intrinsic database in VS2013, but now I come to deploy it and am having problems, despite hours reading MSDN and following tutorials.
I create a deployment package on my development machine, which I then install on the server, but I then need to create a client only package, which points to the server? Does this mean I need to specify the central database as an external data source? Or does this switch happen automatically? Can I publish only the server, and install that on the server machine, (I have already installed the web server package) then publish a separate client package for installing the application on the clients? I need all the clients to update a single database, not all have their own local copies and local databases...
When you "create a client only package" the intrinsic database is running on the client, so nothing point to the server.
A external data source is always external regardless of the app type.
What type of a LightSwitch Application you've selected?
A 2-tier desktop application runs on an end-user Windows desktop. The
database and server components are deployed to the end-user computer.
A 3-tier desktop application runs on an end-user Windows desktop. The
database and server components are deployed to an Internet
Information Services (IIS) server or to Windows Azure.
A 3-tier Web application runs in an end-user web browser. The
database and server components are deployed to an Internet
Information Services (IIS) server or to Windows Azure.
I created my first Java EE application (GWT + Hibernate). I want deploy my application on a Tomcat web server.
Could you give me a step by step tutorial?
You can start with Google App Engine + GWT tutorial if you are trying out deploying into Google Cloud - https://developers.google.com/web-toolkit/doc/latest/tutorial/appengine
This question is massive so I will try to bring it down to some steps that need some research to implement.
1st. You created an application using GWT and Hibernate. That means that you need some kind of a web server that understands java and can re-write the logic from java to javascript (for the clientside), and also connect to the database on the serverside and retrieve the data for the client.
This web server is tomcat so what you need is:
A computer that will work as a server. This could be your own machine or some server you can buy as a hosting solution. Buying something like this requires research and effort on your part and cannot be explained here.
A version of Tomcat or Resin or any other web server that understands java
A domain name. These can be bought from sites like this one, but there are some free ones around the web. They require static ips that is you cannot use them from a home line that changes ips. Even without a domain name you can host your site on the server but you need to access it by writing the machine's ip instead. - optional - A temporary solution would be to use some kind of dynamic dns service on your router.
After having set up tomcat (you might want to give port 80 to tomcat) and the server you can host your application by uploading the war file. You can make a war file from gwt by following the instructions here
To upload the war file you can use the tomcat manager interface, or you can connect to the server and place it manually in the folder used for the web applications.
I know that each step propably needs as much if not more explanation by I hope I cleared the area a little bit here.
