HTTP cos it does much less handshaking and validation...

DO you have any firewalls / security requirements? Because then only HTTP (or HTTP/s) will work.
RMI is faster, because you can send an XMLDocument object over the network, which might take more network bandwidth but will save you the need to serialize it on the client and parse it on the server.

Only because RMI does this for you...  it will still get serialized and deserialized...

Hi

>> DO you have any firewalls ...
is it a problem cause if I open port 1099 it should work no ?

>> Only because RMI does this for you...  it will still get serialized and deserialized

as I understand no matter which one I will use the same work done, am I right?

No.
Serializing the Document is not the same as sending the XML as String and then reparsing it.
It is much more efficient to send the Document object. This is why it takes more network bandwidth.

The Document object is not serializable according to the spec. But, all implementations I know of are defining Document as serialized.

Hi
And what about the firewall , If I will open port 1099 (used for the lookup) is it fine ?

You will have to configure it by hand. Not all sites allow this.
But if you configure the firewall, it will work.

However, if this is a remote site, and you pass other routers and stuff in the middle, you might get stuck.

Why think about HTTP anyway?
