1. 先说一下什么是webservice webservice的 发布一般都是使用WSDL（web service descriptive language）文件的样式来发布的，在WSDL文件里面，包含这个webservice暴露在外面可供使用的接口。 （1）WebService是一个SOA（面向服务的编程）的架构，它是不依赖于语言，不依赖于平台，可以实现不同的语言间的相互调用，通过Internet进行基于Http协议的网络应用间的交互。（2）WebService实现不同语言间的调用，是依托于一个标准，webservice是需要遵守WSDL（web服务定义语言）/SOAP（简单请求协议）规范的。 2. 下面是介绍如何使用axis调用webservice （1）先从官网下载axis相关jar包，地址：http://axis.apache.org/axis/ 官方要求引入如下jar包（将lib下的jar引入即可） axis-/lib/axis.jaraxis-/lib/jaxrpc.jaraxis-/lib/saaj.jaraxis-/lib/commons-logging-.jaraxis-/lib/commons-discovery-.jaraxis-/lib/wsdl4j-.jar 我在项目中实际用到的最少jar如下： H:\libs\axis.jarH:\libs\jaxrpc.jarH:\libs\commons-logging-1.0.4.jarH:\libs\commons-discovery-0.2.jarH:\libs\wsdl4j-1.5.1.jar （2）具体代码实现 package ic; import javax.xml.rpc.ParameterMode; import org.apache.axis.client.Call; import org.apache.axis.client.Service; import org.apache.axis.encoding.XMLType; public class ICServiceTest1 { public static void main(String[] args) { try { String endpoint = "http://localhost:3000/hy/gw/queryConsignOrder?wsdl"; Service service = new Service(); Call call = (Call) service.createCall(); call.setTargetEndpointAddress(endpoint); // WSDL里面描述的接口名称(要调用的方法) call.setOperationName("getLisQueryConsignOrder"); // 接口方法的参数名, 参数类型,参数模式 IN(输入), OUT(输出) or INOUT(输入输出) call.addParameter("icSystem", XMLType.XSD_STRING, ParameterMode.IN); call.addParameter("companyFlag", XMLType.XSD_STRING, ParameterMode.IN); call.addParameter("consignOrderNo", XMLType.XSD_STRING, ParameterMode.IN); call.addParameter("orderNo", XMLType.XSD_STRING, ParameterMode.IN); // 设置被调用方法的返回值类型 call.setReturnType(XMLType.XSD_STRING); //设置方法中参数的值 Object[] paramValues = new Object[] {"4PL","NJHY,NJHF","TC201309172206",""}; // 给方法传递参数，并且调用方法 String result = (String) call.invoke(paramValues); System.out.println("result is " + result); } catch (Exception e) { e.printStackTrace(); } } } ===========================================异常解决=============================================================今天在调用webserivce接口的时候出现了如下异常 警告: Unable to find required classes (javax.activation.DataHandler and javax.mail.internet.MimeMultipart).

这种异常不是程序抛出来的，是由服务器抛出的，所以在程序里抓不到异常。出现此种问题要注意一下是否已经把接口中用到的jar包加进了服务器中或者项目中。 我用的webservice接口的服务器为TOMCAT，此时需要将webservice接口中用到的jar到全部放到tomcat的lib下，这样做后，异常解决 |
