I want to execute a jar file after getting some input from the web page on button click. I tried php exec method , but it runs the jar file at the time of loading the php page (even before button click).

        <input type="button" title="Generate the summary" name="sum" value="Summarize" id="summarize" onclick="summarize()">
    <script>
        function summarize()
        {
            <?php exec("java -jar summarizer_1.jar ",$output); ?>
            <?php echo $output;?>
        } 
    </script>

some people suggested me AJAX but I think its increasing complications in the code. Can there be a simple solution to this problem?

P.S. I used php only to make the .jar call, php is nowhere useful for me in the code.

You are mixing PHP and javascript. Your PHP functions won't work in JS. – abhishekkannojia Mar 20 '17 at 07:19
it works. you can mix php and JS. i do it all the time. Though it is not good practice. – Rotimi Mar 20 '17 at 07:20
Can there be any other way to do this? Any web technology would work for me, as I'm using both js/php to call the .jar – Rakhi Oza Mar 20 '17 at 07:20
What error do you get? via your console(F12) or your network tab in your browser?? – Rotimi Mar 20 '17 at 07:21

@PhpDev What I meant was the PHP is processed on server side so obviously `exec` would execute there itself. – abhishekkannojia Mar 20 '17 at 07:22
there no error in the code , its just that I want the execution of jar on button click but its executing immediately after the page is loaded (even if u do nothing at all) – Rakhi Oza Mar 20 '17 at 07:22
I know php would execute first, my attempt makes no sense, so only I'm asking for some solution – Rakhi Oza Mar 20 '17 at 07:23
Where is the `jar` located? On the server? – mohit Mar 20 '17 at 07:27
Yes, the jar is on server side – Rakhi Oza Mar 20 '17 at 07:27
Take a look at this http://stackoverflow.com/questions/4272666/embedding-java-applet-into-html-file – abhishekkannojia Mar 20 '17 at 07:27
Make sure you the file path of the .jar is correct – Rotimi Mar 20 '17 at 07:27
The path is correct because I am getting the output even before I want. – Rakhi Oza Mar 20 '17 at 07:28
Tried the link @abhishekkannojia .. Its not really relevant to my question – Rakhi Oza Mar 20 '17 at 07:32
where does the variable $output come from in the first line of the function summarize? – Rotimi Mar 20 '17 at 07:33
it's always better for you to do something like that using ajax to connect to your php server which is executes your command line using `exec` – hassan Mar 20 '17 at 07:34
Thanks guys.. AJAX worked. – Rakhi Oza Mar 20 '17 at 07:48
I created a new file called execute.php in which the exec call to .jar was mentioned. `code` – Rakhi Oza Mar 20 '17 at 07:48
