java webservices 以Axis1.4方式 调用sap webservice接口.

1. 首先需要下载Axis1.4 jar包，这个必应搜索大把，下载下来后把jar包加入eclipse工程项目路径中即可.

2. 下载mail.jar和activation.jar 俩个包。下载地址：https://www.eclipse.org/webtools/wst/components/ws/download_instructions_for_jars.html

该网址中含有所有 java webServices 所需要的jar包。如果确实这俩个包，运行时会有：Unable to find required classes (javax.activation.DataHandler and javax.mail.internet.MimeMultipart) 异常.

以下为可以跑的通的代码，需要修改相应的账户密码，路径，方法名，方法参数(在Xmlbody中修改)，下载好相应的jar包.

package frcProject;

import javax.xml.rpc.ParameterMode;

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;

            call.setProperty(org.apache.axis.client.Call.USERNAME_PROPERTY, "account"); // 账号
            call.setProperty(org.apache.axis.client.Call.PASSWORD_PROPERTY, "password");// 密码

            call.setTargetEndpointAddress(endpoint);// 远程调用路径

            call.setOperationName("remoteMethodName");// 调用的方法名

            // 设置参数名: 参数名,参数类型,参数模式

            call.addParameter("xmlBody", XMLType.XSD_STRING, ParameterMode.IN);

            call.setReturnType(XMLType.XSD_STRING);// 设置被调用方法的返回值类型

            try {
                returnData = (String) call.invoke(new Object[] { xmlBody });// 远程调用
            } catch (Exception e) {
                System.out.println(e);
            }

            System.out.println("result is " + returnData);

        } catch (Exception e) {

            System.err.println(e.toString());

        }

    }
