ListGrid远程加载json字符串数据
首先保证加入json的jar.
commons-beanutils-1.7.jar
commons-collections-3.2.1.jar
commons-lang-2.4.jar
ezmorph-1.0.6.jar
json-lib-2.2.3-jdk13.jar
morph-1.1.1.jar

WEB-INF/shared/ds/countryDS4.ds.xml

<?xml version="1.0" encoding="UTF-8"?>
<!-- recordXPath就是countryData.xml里面每一行的节点名字 -->
<DataSource ID="countryDS4" dataFormat="json">
	<fields>
		<field name="countryCode" title="Code" />
		<field name="countryName" title="Country" />
		<field name="capital" title="Capital" />
	</fields>
	<operationBindings>
		<operationBinding>
			<operationType>fetch</operationType>
			<dataURL>../json_fetch.do</dataURL>

	</operationBindings>
</DataSource>
