动态客户端创建

标签： web-services client

我已经创建了一个用于调用Web服务的动态客户端。该客户端调用名为businessWorkItem的Web服务。该服务创建了一个工作项。我在下面给出了代码：

package com.tcs.telecom.tib;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
import org.apache.cxf.endpoint.Client;
import java.lang.reflect.Method;
public class WorkItem 
{
public WorkItem()
{
}
public static void main(String str[]) throws Exception 
{
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient(wsdlname);
Object createWorkItemRequest = Thread.currentThread().getContextClassLoader().loadClass(classname).newInstance();
Method m1 = createWorkItemRequest.getClass().getMethod("externalItemRefId", String.class);
m1.invoke(createWorkItemRequest,"9361117");

Object[] response = client.invoke("createWorkItem", createWorkItemRequest);
System.out.println("Response is " + response[0]);
}
}

当我运行此代码时，我得到未声明的throwable exception.Error log：

有人可以帮我解决这个问题吗？

1 个答案:

答案 0 :(得分：0)

stacktrace表示wsdl中的重复属性。您必须使用jaxb绑定修改wsdl。并提供修改后的wsdl文件以生成客户端。

Caused by: org.xml.sax.SAXParseException; systemId: wlistxsd=./abc.xsd; lineNumber: 47; columnNumber: 32; 'abc' is already defined at com.sun.xml.internal.xsom.impl.parser.ParserContext$1.reportError(ParserContext.java:165)

要使用嵌入式绑定自定义wsdl，您可以执行以下操作。 1.将jaxb名称空间添加到模式定义 2.使用新名称注释重复属性（在示例中，我使用＆＃39; newname＆＃39;注释重复属性）

<s:schema elementFormDefault="qualified" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" jaxb:version="2.0">

<xs:complexType> <xs:sequence> <xs:abc minOccurs="0" /> **<xs:abc minOccurs="1" >** <xs:annotation> <xs:appinfo> <jaxb:property name="newname"/> </xs:appinfo> </xs:annotation> **</xs:abc>** </xs:sequence> </xs:complexType>
