http://tuscany.apache.org/sca-java-bindingjsonrpc.html    Tuscany中实现的binding用法

组件配置文件。Store中引用了Catalog

    <component name="Store">        <tuscany:implementation.widget location="uiservices/store.html"/>        <service name="Widget">        <tuscany:binding.http uri="/store"/>        </service><reference name="catalog" target="Catalog"/> <reference name="shoppingCart" target="ShoppingCart/Cart"/> <reference name="shoppingTotal" target="ShoppingCart/Total"/>    </component>    <component name="Catalog"><implementation.java class="services.FruitsCatalogImpl"/> <property name="currencyCode">USD</property><service name="Catalog"><tuscany:binding.jsonrpc uri="/Catalog"/>   </service><reference name="currencyConverter" target="CurrencyConverter"/></component> 

JSP中将Catalog初始化为object，就可以用它去调用自己的方法了。

<script type="text/javascript" src="../dojo/dojo.js"></script><script type="text/javascript" src="store.js"></script><script language="JavaScript">//@Referencevar catalog = new tuscany.sca.Reference("catalog");//@Referencevar shoppingCart = new tuscany.sca.Reference("shoppingCart");//@Referencevar shoppingTotal = new tuscany.sca.Reference("shoppingTotal");var catalogItems;function catalog_getResponse(items,exception) {if(exception){alert(exception.message);return;}var catalog = "";for (var i=0; i<items.length; i++) {var item = items[i].name + ' - ' + items[i].price;catalog += '<input name="items" type="checkbox" value="' + item + '">' + item + ' <br>';}document.getElementById('catalog').innerHTML=catalog;catalogItems = items;}function init() {try{catalog.get().addCallback(catalog_getResponse);}catch(e){alert(e);}}</script>
