服务器端方法：
public String getSayWS(String name){
Document document = DocumentHelper.createDocument();
// 添加根元素
Element root = document.addElement("root");
Element author1 = root.addElement("book");
author1.addAttribute("id", "aaaaa");
return root.asXML();
}
service-config.wsdd:
<deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<handler type="java:org.apache.axis.handlers.http.URLMapper" name="URLMapper"/>
<service name="UserWS" provider="java:RPC">
<parameter name="className" value="com.ws.UserWS"/>
<parameter name="allowedMethods" value="getSayWS"/>
</service>
<transport name="http">
<requestFlow>
<handler type="URLMapper"/>
</requestFlow>
</transport>
</deployment>
调用：
public String getSay(String name) {
String say = "";
Service service = new Service();
try {
Call call = (Call) service.createCall();
String url = "http://192.168.1.111:8090/Test1WS/services/UserWS";
call.setTargetEndpointAddress(new java.net.URL(url));
call.setOperation("getSayWS");
Object o = call.invoke(new Object[] {});
System.out.println(o);
} catch (Exception e) {
e.printStackTrace();
}
return say;
}

貌似你定义返回类型的时候将String 写成了string
[解决办法]
参数类型必须是标准类型
[解决办法]
server-config.wsdd里没有对getSayWSReturn指定反序列化器呀，类似于下面这种的：
<typeMapping deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory" encodingStyle="" qname="ns5:getProcessInstanceResponse" serializer="org.apache.axis.encoding.ser.BeanSerializerFactory" type="java:com.ttdev.ss.GetProcessInstanceResponse" xmlns:ns5="http://ss.ttdev.com"/>
[解决办法]
在<service> </service>之间加就可以。
[解决办法]
楼主试试这个
<deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java"> <service name="UserWS" provider="java:RPC" style="rpc" use="encoded"> <parameter name="wsdlTargetNamespace" value="http://ws.com" /> <parameter name="wsdlServiceElement" value="UserWSService" /> <parameter name="wsdlServicePort" value="UserWS" /> <parameter name="className" value="com.ws.UserWS" /> <parameter name="wsdlPortType" value="UserWS" /> <parameter name="typeMappingVersion" value="1.2" /> <operation xmlns:operNS="http://ws.com" xmlns:rtns="http://www.w3.org/2001/XMLSchema" name="getSayWS" qname="operNS:getSayWS" returnQName="getSayWSReturn" returnType="rtns:string" soapAction=""> <parameter xmlns:tns="http://www.w3.org/2001/XMLSchema" qname="name" type="tns:string" /> </operation> <parameter name="allowedMethods" value="getSayWS" /> </service></deployment>
