Here are some ways to run a main method using Maven:
Use the exec plugin:
mvn exec:java -Dexec.mainClass="com.example.App"
or, with arguments:
mvn exec:java -Dexec.mainClass="com.example.App" -...
Attach it to a build phase with the build element:
<build>
<plugins>
<plugin>
...
If you want to run main from Maven, it's probably just some test code. You are better off just to write a test case, or call the main method from a test class:
package com.example;
import junit.framework...

Both delegate and live allow you to bind event handlers to elements created in the future, but there are some differences: For .delegate , the event bubbles up to the element on which it is called. For .live , the event bubbles up to the root of the DOM tree, or, as of jQuery 1.4, optionally stop at a DOM element context. DOM traversal methods are not supported for finding elements to send to .live() . Rather, the .live() method should always be called directly after a selector. The opposite of .live is .die . The opposite of .delegate is .undelegate . Note: As of jQuery 1.7, the .live() method is deprecated . Use .on() to attach event handlers. Users of older versions of jQuery...

The spring MVC annotation-driven declaration:
<?xml version="1.0" encoding="UTF-8"?> <beans x... does the following magic : Among others, registers: RequestMappingHandlerMapping RequestMappingHandlerAdapter ExceptionHandlerExceptionResolver in support of processing requests with annotated controller methods using annotations such as @RequestMapping , @ExceptionHandler , etc. Enables Spring 3 style type conversion through a ConversionService instance in addition to the JavaBeans PropertyEditors used for Data Binding. Enables support for formatting Number fields using the @NumberFormat annotation through the ConversionService .

You can submit a form via Ajax by the jQuery Form Plugin . There are two main methods:
ajaxForm : prepares a form for Ajax submit.

ajaxSubmit : submit a form via Ajax.
Example:
$('#myForm2').submit(function() {

There are two ways to get the submit button:
Use the :submit selector (note the space between the form name and :submit ):
$('#the-form-id :submit')
Use attribute selector (also, space between form id and attribute selector):
$('#the-form-id [type="submit"] ')
// or
$(...
jQuery recommends the latter if you are concerned about performance:
Because :submit is a jQuery extension and not part of the CSS specification, queries using :submit cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. For better performance in modern browsers, use [type="submit"] instead.
