2，解决办法

    根据错误提示在google出了各种提示信息，其中一个有用的是开放http的80端口，按照这个提示做了之后，又提示如下错误：

2013-1-8 22:09:34 com.amazonaws.http.AmazonHttpClient executeHelper
信息: Unable to execute HTTP request: peer not authenticated
javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

说明端口号不是根本问题，，，，最后发现原来只要在路径名前加上“http：//“一切问题就都解决了，，

即原代码中

conn.setEndpoint("192.168.0.19");

修改为：

conn.setEndpoint("http://192.168.0.19");

就可以调用ceph s3接口成功。
