How to call an executable jar from php with an argument passed to main method

Question

I have created an executable jar and it works fine. For the testing purpose, I have used a dummy variable in the main method.

Instead, I need to pass a string variable, while calling this executable jar from php.

In short, I need to:

1. Call the executable jar from PHP
2. While calling the jar, I need to pass a string variable from PHP to the main method of the class inside executable jar.

How can I accomplish the aforesaid?

Answer 1

shell_exec("java -jar your_JAR.jar arg1 arg2");

you can also execute Java at all by using exec instead of shell_execute, giving it $output and & $return_var variables (see the linked manual page) and seeing what they contain after the call.
