如何以Java EE兼容方式连接到FTP？

Question

According to the Java EE (EJB) spec, it is not allowed to "listen on a socket, accept connections on a socket, or use a socket for multicast". What is the Java EE compliant way to open a FTP connection?

Answer 1

I'd say a Java EE compliant way to make an FTP connection is through Java EE Connector Architecture(JCA) by using the appropriate ftp adapter.

However the support for JCA is mostly left to the Application Server vendor and I am not sure about the portability your code will have.
