今天使用java axis调用.net发布的webservice接口报了个错，排查半天，感觉代码逻辑没问题，最后发现是jar包冲突！！！

调用接口相关代码：

String url="http://xxxx/WebService/ForDxService.asmx?wsdl";
        Service service = new Service();
        Call call;
        try {
            call = (Call) service.createCall();

            try {
                call.setTargetEndpointAddress(new java.net.URL(url));
            } catch (MalformedURLException e) {
                e.printStackTrace();
            }
            call.setUseSOAPAction(true);
            call.setSOAPActionURI(soapActionURI);
            call.setOperationName(new QName(namespace,"GetOAInterface"));
            call.addParameter(new QName(namespace,"strUnitCode"), //设置要传递的参数
                    org.apache.axis.encoding.XMLType.XSD_STRING,
                    javax.xml.rpc.ParameterMode.IN);
            call.addParameter(new QName(namespace,"strExchangeType"),
                    org.apache.axis.encoding.XMLType.XSD_STRING,
                    javax.xml.rpc.ParameterMode.IN);
            call.setReturnType(XMLType.XSD_SCHEMA);
            String[] str = new String[2];
            str[0] = "A_101247";
            str[1] = "Document";
            Object obj = call.invoke(str);

javax/mail/internet/MimeMultipart

在以下两个Jar包中都存在！

javaee-api-5.jar和javax.mail.jar两个jar包冲突，删掉javaee-api-5.jar即可。
