How should SOA - based application architecture look like?

If I want to create application based on webservices that OSB would serve - what should be it's architecture?

ie. if I use Oracle SOA Suite, I create WebServices that will do my bussiness (talk to DB etc.), put them on OSB (Oracle Servi开发者_StackOverflow中文版ce BUS). If I'd want to create app (webapp) that will utilize those services, how shoud I create project? Would it be war with gui and its logic, separate jar for EJB?

Thanks

If I understand the question, you're looking for how to structure a web application that calls OSB web services. This is no different than a web application calling any other web service.

You shouldn't need EJBs for that, rather you can invoke the web services directly from java via JAX-WS or another mechanism.

For guidelines on structuring an application .ear, see http://java.sun.com/blueprints/code/projectconventions.html or your application server's documentation.
