标 题: Axis客户端调用XFire Web Service的相关问题
发信站: 水木社区 (Tue Nov 24 15:10:18 2009), 站内
Web Service函数定义：
public Boolean getPermission(Map<String, Object> params);
用Axis 1.4写的客户端调用程序：
public static void main(String[] args) {
try {
String endpoint = "http://x.x.x.x:xx/xxxx/ServiceName";
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(new java.net.URL(endpoint));
call.setOperationName("getPermission");
Map<String, Object> params = new HashMap<String, Object>();
params.put("abc", "123");
params.put("def", "456");
Object ret = call.invoke(new Object[] { params });
System.out.println("Sent '" + params + "', got '" + ret + "'");
} catch (Exception e) {
System.err.println(e.toString());
}
}
用上面的客户端代码调用Axis 1.4实现的Web Service，没有问题，可以成功得到Map参数内容，并返回Boolean对象。Axis生成的WSDL如下(节选)：
<wsdl:definitions>
<types>
<schema>
<complexType name="mapItem">
<sequence>
<element name="key" nillable="true" type="xsd:anyType" />
<element name="value" nillable="true" type="xsd:anyType" />

</wsdl:input>
<wsdl:output name="getPermissionResponse">

<wsdlsoap:address location="http://x.x.x.x:xx/services/ServiceName" />
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
然而用同样的客户端代码调用XFire 1.2.6写的Web Service，就会出问题。
调用时，XFire Web Service端报Exception：
IndexOutOfBoundsException: Index: 1, Size: 1
XFire生成的WSDL如下(节选)：

客户端是给一个门户网站用的，会有很多子系统来门户网站注册自己的Web Service，供门户调用。目前已经有不少用Axis1.4搭建的子系统Web Service上线运行了，因此如果需要修改客户端调用代码，则必须保证能够正常调用这些已有的Web Service。
并且，作为门户来讲，Web Service调用部分的代码只能把Web Service地址作为参数传进去，代码的其它部分不能因为调用的Service不同而有所不同，所以，每注册一个子系统Web Service就新生成一段客户端代码的做法是不现实的。
求大侠指教！
