Dear Authors,

During one of Oracle Workshops , one of your peers from Oracle ( I think it is Raghu- not sure though ) talked about SOA and how important it is in Current Business environment.

Do you talk about exposing EJB as webservice in the book ? Also , I would like to hear some experts to comment on exposing a Database PL/SQL directly as webservice as opposed to creating a Entity bean and then exposing that as webservice .

Thanks in advance

Hi Ram,

To keep the book down to a manageable size, we chose not to discuss web services. Fortunately, Oracle offers a number of online resources that discuss these issues. On the EJB 3 and JPA sites on OTN you can download howtos that show how to expose EJB 3 session beans as web services quickly and easily.

The Oracle Web Services stack included with OC4J also includes a product called DBWS that was designed to expose PL/SQL packages as web services. It produces a standard EAR file that can be deployed to OC4J and creates a web service operation that corresponds to each of the PL/SQL package operations. Check out the web services documentation in a recent OC4J release for information on DBWS.

Cheers,

Merrick
