Hello first of all!

Sorry for my not really perfect english, but i am not a native
speaker.

The question i have is really general and depends on webservices.

I have to write a work about BPEL and have to figure out, how to bring
an application available over a webservice.
The appplication is more a less a informationserver, who is able to
extract informations from the web and transmitts the info via mail,
sms or something else.
So what do i need to offer this application via an webservice in
BPEL4WS. The application is completley written in java. Sorry for
this general question but i am an noob in this topic.
Thx for info!
