Calling Java method from HTML file

Question

I'm building a web application, and the following Java method will be called dynamically several times when the application's web page is opened in a browser:

Java:

public String getProductImgURL (int i) // image at index i
{
    return products_to_display.get(i).getImage();
}

I want to be able to call this function in for loop in the HTML file, I tried making the calls using JavaScript's document.write in the following way, however it didn't work.

Part of the JavaScript inside HTML file:

   for(var i=0;i<len;i++)
   {
        document.write(
        "<img src=\"@model.getProductImgURL(i)\">"+
        "<br>"
        );
   }

It doesn't work, the weird thing is that when I pass a constant number to the function above in JavaScript, it works just fine!

I'm new to this, can anyone help me find a way calling the Java function above in the HTML file using JavaScript?

Thanks

you cannot call a serverside method via clientside code. they are not the same thing, they dont live on the same machines etc..

you will need to make an http call to a server that will call the java method.

Is it possible to get clearer directions/example please?

no, your question is too broad - I don't have time to explain how the internet works

Before I posted the question I made some research on the internet. From stuff I read, I think the solution can be AJAX, however I didn't really understand how I can use it. Especially the part of combining AJAX and where the Java method call. That is an example of what I mean by "directions" - I'm not asking from anyone to explain how the WHOLE internet works.

sorry, but your question is still to broad. you want me to explain how client server applications work? you can google that.
