how to call java method from actionscript

Question

I've just now started working on Flex. May be its basic question but I’m not aware of it – how can I call a java method from actionscript. I want to call some java method on double click of a event. Can you please let me know how to proceed on this?

Do you mean call a JavaScript method via External Interface? — Jason Sturges

In Flash Builder, under the Data menu, there are data service wizards:

data-services

These wizards auto-generate code and are convenient for connecting to WSDL:

wsdl

Or HTTP Services:

Accessing data services overview has example implementations, such as this example calling a restaurant web service with responder returning value objects from service.

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark"
               xmlns:mx="library://ns.adobe.com/flex/halo"
               xmlns:employeesservice="services.employeesservice.*"
               xmlns:valueObjects="valueObjects.*">

    <fx:Declarations>
        <s:WebService id="RestaurantSvc"
                      wsdl="http://examples.adobe.com/flex3app/restaurant_ws/RestaurantWS.xml?wsdl" />
        <s:CallResponder id="getRestaurantsResult"
                         result="restaurants = getRestaurantsResult.lastResult as Restaurant" />
    </fx:Declarations>

    <fx:Script>
        <![CDATA[
            import mx.controls.Alert;

            protected function b1_clickHandler(event:MouseEvent):void
            {
                getRestaurantsResult.token = RestaurantWS.getRestaurants();
            }
        ]]>
    </fx:Script>

    <s:Button id="b1"
              label="GetRestaurants"
              click="button_clickHandler(event)" />

</s:Application>

Can you also please let me know how can I call this http/SOAP service on double click event?

Example, and some references added. There are numerous approaches to this both using these wizards as well as programmatic approaches. Data services is a wide topic, but hopefully this demonstrates some options for you to choose in your implementation.
