今天开发项目遇到一个问题，简单记录下，希望能帮到遇到同样问题的同学

我使用Axis1.4开发webservice客户端，客户端代码如下：

Service service = new Service();

Call call;

try {

call = (Call)service.createCall();

call.setTargetEndpointAddress(d2Url);

QName qn = new QName("", "CMSID");

call.addParameter(qn, XMLType.SOAP_STRING, ParameterMode.IN);

QName qn2 = new QName("", "CorrelateID");

call.addParameter(qn2, XMLType.SOAP_STRING, ParameterMode.IN);

QName qn3 = new QName("", "ContentMngXMLURL");

call.addParameter(qn3, XMLType.SOAP_STRING, ParameterMode.IN);

call.setReturnClass(ContentDeployReqResponse.class);

QName mapping = new QName("iptv", "ContentPreloadReqResponse");

call.registerTypeMapping(ContentDeployReqResponse.class, mapping,

new BeanSerializerFactory(ContentDeployReqResponse.class, mapping),

new BeanDeserializerFactory(ContentDeployReqResponse.class, mapping));

call.setOperationName(new QName("iptv", "ContentPreloadReq"));

return call;

} catch (ServiceException e) {

e.printStackTrace();

}catch(Exception e){

e.printStackTrace();

}

return null;

ContentDeployReqResponse类代码如下：

import java.io.Serializable;

import javax.xml.bind.annotation.XmlAccessType;

import javax.xml.bind.annotation.XmlAccessorType;

import javax.xml.bind.annotation.XmlElement;

@XmlAccessorType(XmlAccessType.FIELD)

public class ContentDeployReqResponse implements Serializable{

/**

*

*/

private static final long serialVersionUID = -6709028467973715698L;

@XmlElement(name = "ErrorDescription")

private String errorDescription;

@XmlElement(name = "ResultCode")

private int resultCode;

public int getResultCode() {

return resultCode;

}

public void setResultCode(int resultCode) {

this.resultCode = resultCode;

}

public String getErrorDescription() {

return errorDescription;

}

public void setErrorDescription(String errorDescription) {

this.errorDescription = errorDescription;

}

}

调用服务端后返回的xml如下：

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">

<S:Body>

<ns2:ContentPreloadReqResponse xmlns:ns2="iptv">

<return>

<ResultCode>0</ResultCode>

<ErrorDescription>success</ErrorDescription>

</return>

</ns2:ContentPreloadReqResponse>

</S:Body>

</S:Envelope>

Axis在解析xml为ContentDeployReqResponse  时出现以下错误：

[2013-12-19 17:51:24,234 ERROR] Exception: org.apache.axis.client.Call.invoke(Call.java:2469)

org.xml.sax.SAXException: Invalid element in opt.fonsview.cmm.ws.ContentDeployReqResponse - ResultCode

首先想到的是将ContentDeployReqResponse  中的属性首字母大写，发现还是出现以上问题，查看源代码，Axis用到的是javax.bean相关类来生成ContentDeployReqResponse  类信息，我猜测应该是为了跟java规范保持一致，所以在保存属性名的时候是将首字母小写，而返回的xml中首字母是大写，导致出错。

采用第二种方法，改写Axis相关源码，替换jar包中文件，运行成功，改写的源文件为org.apache.axis.encoding.ser.BeanDeserializer 的onStartChild方法

改写之前：

if (propDesc == null) {

// look for a field by this name.

propDesc = (BeanPropertyDescriptor) propertyMap.get(localName);

}

改写之后：

if (propDesc == null) {

// look for a field by this name.

for(Iterator iter = propertyMap.keySet().iterator(); iter.hasNext();){

String key = (String)iter.next();

if(key.equalsIgnoreCase(localName)){

propDesc = (BeanPropertyDescriptor) propertyMap.get(key);

break;

}

}

}

开发过程中还遇到一个问题未解决：Axis在解析返回的XML时耗费的时间过长，达10分钟之久，发现问题出在InputStream的read方法上，什么原因？欢迎碰到相同的同学一起探讨
