simple question here. If I develop an app in C# which connects to Oracle, I need to have oracle client installed on the client machine. My questions are :
Do I have to install the full client (or Instant client), or I can deploy just few dlls with my C# app ?
Same question but not for C# but for Java app. Is the Oracle client required there ? Can I simply deploy few dlls instead of installing the full client ?
Thank you
From poking around on the Oracle site, it looks like what you want is the "Instant Client" download.

I am learning Java and am trying to do some experiments with networking Java programs.
I have a program made in 2 parts with a client and a server and it works in local testing but the program actually has usefulness for me and a friend of mine and I want to put the server online so both of us can connect to it and use it.
Where/How can I put the program online and have it running so that the client programs can connect to the ServerSocket with an ip address? (Preferably free)
If you dont want to pay server hosting then I would open a virtual server on my computer, then playaround with modem and forward related port to server ip. I would use a port more than 40000. Then just send your ip and port your friend or update application.
If you really want the application to go live within 5 mins, try Jelastic. If you have built a WAR file, simply sign up with their server,choose a provider closest to your geo location, configure Tomcat and you can upload the WAR file through their fantastic web console. Otherwise if you have some source control system(SVN,GIT etc), you just connect and build it with their Maven console and you can be ready. I used it for my start up(Cloudlabz) and really found it exciting.

You could also consider the cheapest Rackspace Cloud Server. You'll get a full fledged Linux server (distribution of your choice) for about USD 11/month. I've done that now and then myself to try things out.
Just install Java on it and you're good to go.

is that what you want for this?
This is a free web app for you to run your program online....so you can just paste your code and run it.
On the cloud you could use two different services in order to host your Java application.
IaaS (Infrastructure as a Service). Where you can just rent a specific infrastructure on the cloud and you could install and configure all the services that you need.
PaaS (Platform as a Service). In this case, you still enjoy the infrastructure on the cloud + the service Aaren full pre-configured. It means that you can deploy your application without installing or configuring anything. You just need to deploy your application. You have an example about how it works here. Also, you usually can test your Java apps on the cloud without paying.
You should host the server in Heroku ,they offer a free hosting with limits , I have an app there
I would like to know if I purchase a VPS service(linux based) over the net.
Do I need Tomcat to be installed in order to launch my java based server (socket server)?
If yes Which version do I need, and can you please give me a reference for an online guide for how to install and run things on a VPS which is based on Linux.
Thanks
If your are not deploying web apps (WAR's), you don't need a application server like tomcat or glassfish. So to run your java based server, you only need the JRE.
Get a Windows-based VPS if you are not familiar with Linux, as you have to administrate the server (apply patches, etc.), if it is not managed by your provider.
Have a look at this Superuser question for Linux books.
Ok so I'm trying to develop a server for an android app that I'm developing.
Basically it's an application that needs to connect with other phones through a database system.
I was thinking of using an sql database to store the simple data I need to exchange.
What type of server should I be using?
What language should I be writing the database code in (if besides SQL)?
How do I get the android application to communicate and exchange information with the database?
Is there a type of virtual server I can use to test my app?
The server type and language choices very much depend on your skillset and environment. However, I'd suggest exposing queries to your database either through JSON or XML, and presenting through a web server.
PHP & MySQL are as good a choice as any, as you can run the same code on UNIX, Linux, Solaris, or MacOS servers. Of course, using a J2EE environment with JDBC drivers to a generic server is also a good choice, especially if you need to share any classes between Android and your server.
By 'virtual server' I assume you mean 'virtual handset', in which case the Android emulator in the SDK might be good enough (although it is painfully slow), or just use a real Android device plugged in to your development machine.
Hope this helps,

I have previously installed xampp on my remote linux server. So I already have php pre-compiled. Java also. I installed a jetty server. Do I need other configuration to it to run both PHP and JSP?
I want to use JSP and jetty server instead of PHP and apache for scaling issues regarding a notification system that I will soon apply. Any feedback on this descision will be apprecitied
See their documentation for PHP support.
I followed the recaptcha instructions and created a simple app that works if I run it in Eclipse using a local Tomcat server but the same files give an error (verify-params-incorrect) when validating the user's response when run in Eclipse using the local Google App Engine SDK.
Are you using the Java code linked to on the reCAPTCHA site? I took a quick look at it, and I suspect that the SimpleHttpLoader class uses some Java classes that are no allowed by Google's AppEngine.
So, here is what I know: Running locally, I get the same error as you.
But, when I deploy it to AppEngine, it works! For the forum posts I've read, I suspect it has to do with the remote IP address (127.0.0.1) when running locally.
This is sort of an impertinent answer, but are you sure you really need to pester your potential users with a captcha at all? There's a great article over on sitepoint entitled "10 Things to Check Before Using a CAPTCHA"
I had no problems at all locally with Google App Engine or deployed with recaptcha4j-0.0.8.jar and Google App Engine SDK 1.6.6. I followed the reCaptcha tutorial for Java at https://developers.google.com/recaptcha/docs/java.
