Call java method on button click

Is it possible to call a method in Java by button onclick in JSP?

For example:

Java:

@UrlBinding("/Student/import.action")
public class StudentAction implements ActionBean {

  public void testMe() {
      //do something
    }
}

JSP

<stripes:form beanclass="com.example.action.StudentAction">
   <input type="button" value="Test" onClick="call testMe"/>
</stripes:form>

I read some posts on Internet that it could be done by Ajax/jQuery, but I couldn't understand how they do it. I just know itshould be something like this:

$.ajax({
    type:"POST"
    url: 
})

or

$(document).ready(function() {
    $("#button").click(function(){

    })
})

is there any other way to do this, and if no, I would appreciate a simple explanation of how to do it with Ajax/JQuery.

Note: I don't want to use submit input or stripes:submit!

If you have an ActionBean (which is a servlet deep down), you can bind an URL to it with @UrlBinding (as you already do). You just need to make a HTTP request to that URL using Ajax in the 'click' event handler of the button.

So you could have this markup:

<stripes:form beanclass="com.example.action.TestMeActionBean">
    <input type="button" value="Test" onClick="testMe()"/>
</stripes:form>
<script>
function testMe () {
    $.ajax({
        type: 'post',
        url: 'action/testMeAction',
        ...
    });
}
</script>

On the server side, you just need to create the handling action:

@UrlBinding("/action/testMeAction")
public TestMeActionBean implements ActionBean {

After this, you only need to write a handler method. For example, using your method declaration:

    @DefaultHandler
    public void testMe() {
        //do something
    }
}

It will not call Java method, you have to write Servlet then call the doGet() or doPost()method of Servlet on form submission or using ajax call. refer this example
