本文介绍了一个使用AXIOM的客户端示例，演示如何通过Axis2与远程服务交互，包括发送请求和接收响应的过程。

服务端代码参照：http://blog.youkuaiyun.com/kunshan_shenbin/archive/2009/01/20/3839417.aspx

注意：测试时发现需要追加mail-1.4.jar。

AXIOM客户端可先参照：http://blog.youkuaiyun.com/kunshan_shenbin/archive/2009/01/20/3839781.aspx

这次使用Axis2官方网站上的代码：

如下图所示建立工程：

代码：

AXIOMClient.java

package client.axiom; import org.apache.axiom.om.OMAbstractFactory; import org.apache.axiom.om.OMElement; import org.apache.axiom.om.OMFactory; import org.apache.axiom.om.OMNamespace; import org.apache.axis2.Constants; import org.apache.axis2.addressing.EndpointReference; import org.apache.axis2.client.Options; import org.apache.axis2.client.ServiceClient; public class AXIOMClient { private static EndpointReference targetEPR = new EndpointReference( "http://localhost:8080/Axis2Web/services/StockQuoteService"); public static OMElement getPricePayload(String symbol) { OMFactory fac = OMAbstractFactory.getOMFactory(); OMNamespace omNs = fac.createOMNamespace( "http://quickstart.samples/xsd", "tns"); OMElement method = fac.createOMElement("getPrice", omNs); OMElement value = fac.createOMElement("symbol", omNs); value.addChild(fac.createOMText(value, symbol)); method.addChild(value); return method; } public static OMElement updatePayload(String symbol, double price) { OMFactory fac = OMAbstractFactory.getOMFactory(); OMNamespace omNs = fac.createOMNamespace( "http://quickstart.samples/xsd", "tns"); OMElement method = fac.createOMElement("update", omNs); OMElement value1 = fac.createOMElement("symbol", omNs); value1.addChild(fac.createOMText(value1, symbol)); method.addChild(value1); OMElement value2 = fac.createOMElement("price", omNs); value2.addChild(fac.createOMText(value2, Double.toString(price))); method.addChild(value2); return method; } public static void main(String[] args) { try { OMElement getPricePayload = getPricePayload("WSO"); OMElement updatePayload = updatePayload("WSO", 123.42); Options options = new Options(); options.setTo(targetEPR); options.setTransportInProtocol(Constants.TRANSPORT_HTTP); ServiceClient sender = new ServiceClient(); sender.setOptions(options); sender.fireAndForget(updatePayload); System.err.println("price updated"); OMElement result = sender.sendReceive(getPricePayload); String response = result.getFirstElement().getText(); System.err.println("Current price of WSO: " + response); } catch (Exception e) { e.printStackTrace(); } } }

运行测试通过,看来上文所说的Bug现在自相矛盾了，呵呵。
