Tej,

One of the ways to call a server side Service from a Webpage is, Post a
request to a request, This request is defined in controller.xml file of you
webapp. The request entry in controller will look like

<request-map uri="lightCreateGlJournalEntry">
<security https="true" auth="true"/>
<event type="jsonservice" invoke="createGlJournalEntry"/>
<response name="success" type="view" value="none"/>
<response name="error" type="view" value="glJournalEntryData"/>
</request-map>

When a controller processes this request it calls createGlJournalEntry
service, in your case this service name will be what ever service you want
to call. In Ofbiz we already have a Request event handler that will call a
service for you and return response as JSON object.
This event is still new so by default its not added to all the controller.
In order to be able to call a service using this event hadler you have to
register it with controller that you do by adding following line to your
controller in the top section,
In the controller of your webapp, add following handler
<handler name="jsonservice" type="request" class="
org.ofbiz.webapp.event.JSONServiceEventHandler"/>

Now you need a javascript function that will call this request from webapp,
this Function will look something like this,
function getGCInfo() {
if (document.setPaymentInformation.addGiftCard.checked) {
dojo.io.bind({url: "<@ofbizUrl>quickAnonGcInfo</@ofbizUrl>",
load: function(type, data, evt){
if(type == "load"){
document.getElementById("giftCardSection").innerHTML = data;
}
},mimetype: "text/html"});
} else {
document.getElementById("giftCardSection").innerHTML = "";
}
}

After this you need to explore how to handle a JSON response.
