Best network protcols for Java App Client through firewall

[ruilin yang]

What are best network protcols to use for an java application client (e.g. swing, etc. ) to communicate to a remote server through a firewall ?
Practically, I am thinking to use (xml through https/http). Is this is the xml-rpc ?
We can do rmi tunneling. However, It is not as good as xml-rpc ?
Please clarify for me.
Thanks

What kind of server is it?
I would consider SOAP i.e. XML over HTTP/HTTPS, basically

Say J2EE server application Intranet/internet.

How about the equivalent of Soap in Java ? XML-RPC ?

XML-RPC and Soap are two different protocols. Soap is newer and cooler . Check out the Fall '01 JAX Pack from Sun, which includes the JAXM Soap messaging package. It exposes Soap at a pretty low level, for something more high level you'll have to wait a bit longer for JAX-RPC; it promises to make Soap method calls as easy as RMI method calls. Also have a look at Apache SOAP and Apache Axis.
For an XML-RPC implementation, see for example Apache XML-RPC.
