I need to run a single java program (which will change the content of some text files) on my new website. What's the easiest way to do that for example using php code? Do I need to install JVM or any other software in order for this to work? Please guide on how to do this step by step if possible.

You have to install a Java Runtime Environment (JRE) on your server to be able to run a java program.

http://www.oracle.com/technetwork/java/javase/downloads/jre7-downloads-1880261.html

To execute a java program in php, you can simply use the exec() function :

exec("java -jar yourProgram.jar");

  • So if I have access to the server only by FTP client (the page is hosted on someones server) should i download JRE version for 32-bit linux and then copy it to the server using FTP? – OrdinaryProgrammer Jan 22 '16 at 11:29
  • Yes it should be possible if you send the uncompressed folder through FTP. But maybe the `java` command will not be recognized on the server so you will have to put the whole path to java in your php command (something like `exec("/install_dir/jre1.8.0_71/bin/java -jar yourProgram.jar");` – Patrick Jan 22 '16 at 16:30
