Streaming over Webservices

[cipherous]

hey guys

Please excuse me if I am sounding naive, I am no SOA expert.

I need a way to constantly feed data to a client, its almost as if the client was a stock ticker.

I was wondering if you ever heard of streaming soap over a webservice (or if its actually possible). Is this more of a ESB level paradigm?

there is a streaming XML parser called STax but you need to open a socket stream in order to get access to the source. However, opening sockets defeats the purpose of a SOA architecture and will cause some firewall issues.

any information would be greatly apperciated.

I found that jbossWS does not support Stax, STax is supported in glassfish and axis2

STAX doesn't help here:

I need a way to constantly feed data to a client,

It depends on the transport layer capabilities. I.e. if you are using HTTP you are tied to request/response patterns that don't allow constant data streams.

ah ok

thanks for the input,

do you know of a way to constantly (and efficiently) to feed data over webservices?

thanks

Have a look at WS-Eventing, this might address your use case.
