B4J Question A cheap - or better - free host where to run a B4J program - anyone ?

semar · Mar 5, 2019

Dear all,

is there any remote cheap or (better) free host provider, where is possible to run a B4J .jar on it ?

Just out of curiosity: where do you run your B4J applications ?

Tips and suggestions are more than welcome,

Sergio

VPS = Virtual Private Server , with Ubuntu or Windows Server. I pay for one of my vps 14€ per month and have 30gb RAM 800GB SSD with 8 cores. VPS are cheap with a lot of Power.

Danke Alexander !
Actually I have a host provider which hosts my website (well, a w.i.p. one on strato.de) and there is also a MySql database at my disposal. The question, in order to reach the database from within the B4J application, are special requests to be met, or it would work "out of the box" providing a valid connection string ?

That is very cheap for that VPS - My server (Full hosted Win Server - similar spec - running 2x Xeons) costs me (R 1800) per month - about 106 Euro's, but I have a 99.8% uptime contract with 5x public IP's and am free to do with it what I want.

The Provider is contabo. The Servers are in Germany, Nürnberg (Nuremberg) and München (Munich).

@semar It definately depends on your location / the location of your users. Ive also had good experience with the Provider that @Alexander Stolte mentioned.

I mean, if the B4J App resides on contabo, and the MySql on strato.de, can the B4J App connect to the MySql database ?

Search for AWS Amazon, 12 months free.

Yes, assuming that the database server and firewall are configured to allow external TCP/IP connections.

But without Backups

My MySQL database is on Amazon RDS, Because i dont want 4 extra vps for the database backend. The vps are connected via a loadbalancer. Yes you can host a mysql Server on a. Different Server, but you Need Good Firewall rules IP forward etc.

This is not a VPS or a solution where a .jar file can run.

Indeed sir, I thought too exacltly the same after I wrote my message..

semar · Mar 5, 2019

Ok, I think I will follow the contabo route. Now I need some help about configuration. Is it easy to install a B4J Application on a linux server, or should I take a windows server instead ?

Which client/console do I need in order to connect to it ?

Are special tools required for a B4J installation on a linux VPS ?

Yes, for me, but where I started with ubuntu it was very hard for me since I came from windows server.

semar said:

On a Windows Server you pay for the lincence and do not get full performance with most providers, as with ubuntu where you have no license costs.

semar said:

For all commands, i recommend Putty (SSH) and for file transfare dont use FTP, because there is no "S" in the name and the "S" stands for Secure. I use for file tranfers on my VPS's WinSCP (Thanks to @alwaysbusy for this tip in one of a comment in the Forum), with WinSCP you Upload and Download files over SSH and this is safe because it is encrypted (SSH = Secure Shell)

semar said:

No, B4J (B4A, B4I and B4R) are Windows programs, but if you want to run the .jar file then you need the java jre.
You can install it with the following command:

B4X:

sudo apt install default-jre

But maybe @Erel can move this thread to the B4J Question Forum, so the search engine can indexing the tips and tricks here

Vultr or DigitalOcean had very cheap plans, and you can install for free Plesk ( Cpanel Clone ), with that manager you can install Java, PhpMyAdmin, the recomended solution its migrate your database to your new VPS.

Also you can install free Webmin an Cpanel like webadmin. for your server

Im using NJ New York Datacenter no problems after more than 1 year of uptime.

If you really like command line tools, Putty will come with scp, a secure copy command that works over SSH.

++ for Webmin. 1) I'm often too lazy to use the command line. 2) I get my morning reports letting me know if any updates need to be performed. 3) It's written in Perl and I'm a sucker for Perl (vs Pascal - hates me, Lisp - makes my brain hurt, Objective-C - makes my brain melt, Python - Perl was first).
