5.生成webservice服务端代码
在package explorer窗口中选择右键new--others--Axis2 Service Archiver

下一步，指定class文件的位置：

下一步，选择SKIP WSDL
http://dl.iteye.com/upload/attachment/270302/78b8d660-c5ee-388e-bdba-7748d7ea199f.jpg[/img]

下一步，默认跳过

指定services.xml文件路径：

指定输出aar包的位置：

如果弹出成功界面那么生成成功！

6.发布webservice服务
将生成的 *.aar包拷贝到，%TOMCAT_HOME%\webapps\axis2\WEB-INF\services\下，启动tomcat即可
7.测试webservice服务
--------上传文件代码段------

         //调用WebService服务上传待发信息的文件 
        if(SystemParameter.IsSendSMS){ 
        IOUtil.appendStr2File(SystemParameter.smsSendDir +File.separator+ "sms_send_list_" + sendtime+ ".txt","EOF", true, IOUtils.LINE_SEPARATOR_WINDOWS); 
        File uploadFile=new File(SystemParameter.smsSendDir +File.separator+ "sms_send_list_" + sendtime+ ".txt"); 
        if(uploadFile.exists()){ 
        boolean hasUpload= fileClient.upload("sms_send_list_" + sendtime,uploadFile, "txt"); 
        if(hasUpload){ 
        LOG.info("上传待发催报短信息文件："+uploadFile.getName()+"成功!"); 
        try { 
Thread.sleep(10000); 
} catch (InterruptedException e) {
