【】org.apache.axis2.AxisFault: Broken pipe问题

各位大侠，请教个问题，本人使用axis2（版本1.4.1）来开发webservice，其中客户端编写如下：

public String sendBossXml(String sendXml, String invokeMethod) {

		String retXml = "";

		log.info("sendXml:\n"+sendXml);

		RPCServiceClient serviceClient = null; // 使用RPC方式调用WebService

		

		try {

			

			serviceClient = new RPCServiceClient();

			Options options = serviceClient.getOptions();

			EndpointReference targetEPR = new EndpointReference(v_url); // 指定调用WebService的URL

			options.setTo(targetEPR);

			options.setTimeOutInMilliSeconds(new Long(5000));//设置超时时间5秒



			Class[] classes = new Class[] { String.class }; // 指定方法返回值的数据类型的Class对象



			Object[] opAddEntryArgs = new Object[] { sendXml }; // 指定方法的参数值

			QName opAddEntry = new QName(v_spaceName, invokeMethod); // 指定要调用的getGreeting方法及WSDL文件的命名空间



			// 调用方法并输出该方法的返回值

			retXml = (String) serviceClient.invokeBlocking(opAddEntry,

					opAddEntryArgs, classes)[0];

			

			log.info("retXml:\n"+retXml);



		} catch (AxisFault e) {

			e.printStackTrace();

			

		}finally{

			try {

				serviceClient.cleanup();

			} catch (AxisFault e) {

				e.printStackTrace();

			}

		}



		return retXml;

	}



	

	

	public static StringBuffer readFile(String fileName) throws IOException {

		StringBuffer stringBuffer = new StringBuffer();

		BufferedReader bf = new BufferedReader(new FileReader(fileName));

		String line = "";

		while ((line = bf.readLine()) != null) {

			stringBuffer.append(line);

			stringBuffer.append("\n");

		}

		return stringBuffer;

	}



	public static void main(String[] args) {



		BossService bs = new BossService();

		

		try {

			

			StringBuffer sendXml = readFile("C:\\Users\\Admin\\Desktop\\xml\\querySend.xml");

			System.out.println("sendXml=\n" + sendXml);

			

			String retXml = bs.sendBossXml(sendXml.toString(),

					"GSMQueryService");

			

			System.out.println("retXml=\n" + retXml);

			

		} catch (IOException e) {

			e.printStackTrace();

		}

	}

调用之后报如下错误：
