web service 问题 急！(100分)

我现用java写一个webservice 其中一个方法要返回一个数据表的记录，而客户端用
的是delphi，请问是否需要进行数据类型转换，是不是要自已在web服务端中封装一
个xml文件，然后再传到客户端时，再进行解析，如果是这样那么怎么来封装会比较
好呢。望高手指教。

hehe

JB 开发webservices时，会生成一个XML文件，根据这个文件，声成Delphi客户端

re:HANFI,你上面的这个xml是一个公布给客户端的一个接口吧，而我是要公布接口后，再调用里面的方法，来返回表数据的，然后再赋给clientDataset。

还有一个问题，如何在客户端用sql语句来提交二进制的数据呢，如：图片等。
